Freeze Specified Layers in a Layout Viewport

Freeze Specified Layers in a Layout Viewport

A major benefit to using layout viewports is that you can selectively freeze layers in each layout viewport. You can also specify default visibility settings for new viewports and for new layers. As a result, you can view different objects in each layout viewport.

You can thaw or freeze layer in current viewport and future layout viewports without affecting other viewports. Frozen layers are invisible. They are not regenerated or plotted. In the illustration, the layer showing terrain has been frozen in one viewport.


Thawing the layer restores visibility. The easiest way to freeze or thaw layers in the current viewport is to use the Layer Properties Manager.

In the Layer Properties Manager, on the right side, use the column labeled VP Freeze to freeze one or more layers in the current layout viewport. To display the VP Freeze column, you must be on a layout tab. Specify the current layout viewport by double-clicking anywhere within its borders.

Freeze or Thaw Layers Automatically in New Layout Viewports


You can set visibility defaults for specific layers in all new layout viewports. For example, you can restrict the display of dimensions by freezing the DIMENSIONS layer in all new viewports. If you create a viewport that requires dimensions, you can override the default setting by changing the setting in the current viewport. Changing the default for new viewports does not affect existing viewports.

Create New Layers That Are Frozen in All Layout Viewports

You can create new layers that are frozen in all existing and new layout viewports. Then you can thaw the layers in the viewports you specify. This is a shortcut for creating a new layer that is visible only in a single viewport.

To freeze or thaw layers in the current layout viewport

1. Double-click within a layout viewport to make it current.
2. Click Home tab  Layer panel  Layer Properties.
3. In the Layer Properties Manager, select the layers to freeze or thaw.
4. Hold down CTRL to select more than one layer. Hold down SHIFT to select a sequence of layers.
5. Click the icon in the VP Freeze column for one of the selected layers.
6. Click OK.

To view a list of layers that are frozen in the current viewport

1. Click a layout tab.
2. Double-click within a layout viewport to make it current.
3. Click Home tab  Layer panel  Layer Properties.
4. In the Layer Properties Manager, look at the VP Freeze column for the Freeze/Thaw in Current Viewports icon.
5. Click OK.

To freeze or thaw layers in all viewports

1. Click a layout tab.
2. Click Home tab  Layer panel  Layer Properties.
3. In the Layer Properties Manager, select one or more layers to freeze or thaw.
4. Hold down CTRL to select more than one layer. Hold down SHIFT to select a sequence of layers.
5. In the Freeze column, click the icon to freeze or thaw.

To freeze or thaw layers in paper space

1. Click a layout tab.
2. Make sure that you are in paper space. (On the status bar, PAPER is on.)
3. Click Home tab  Layer panel  Layer Properties.
4. In the Layer Properties Manager, select the layer or layers you want to freeze or thaw.
5. In the Freeze column, click the icon to change a layer's state. The sun icon means that a layer is thawed; the snowflake icon means that a layer is frozen.
6. Click OK.

To freeze or thaw layers in all new viewports

1. Click a layout tab.
2. Click Home tab  Layer panel  Layer Properties.
3. In the Layer Properties Manager, select the layer or layers you want to be automatically frozen or thawed in new viewports you create.
4. Hold down CTRL to select more than one layer. Hold down SHIFT to select a sequence of layers.
5. In the New VP Freeze column, click the icon to change a layer's state. The sun icon means that a layer is thawed; the snowflake icon means that a layer is frozen.
6. Click OK.

 To create new layers that are frozen in all viewports

1. Click a layout tab.
2. Click Home tab  Layer panel  Layer Properties.
3. Click the New Layer button to create a layer.

CAD for Collaborative Design

New Optics is a leading lighting and backlight products manufacturer and supplier in Korea. Aiming to provide the most efficient light source for the next generation of lighting products, they have been providing high quality products and services to users since their foundation in 2005. Being high-brightness, energy-efficient, and long-lifespan, their main product, BLU, has become one of the authorized suppliers of LG Display. 

The Need

New Optics has very strict requirements on collaboration since the majority of their designers work in teams on extensive and sophisticated projects. Besides, in order to further boost profitability, they are increasingly seeking out CAD software that incurs less financial and time investment. They think light weighted CAD software may be a good choice to meet both requirements.

The Solution

Recommended by the design team in their Chinese branch, New Optics decided to introduce ZWCAD+ into their Korean headquarters. The compatibility of ZWCAD+ is highly appreciated among those who have already used it. Designers and customers can open and edit most drawings saved by mainstream CAD software, enabling better collaboration and more accurate outputs. “We are enjoying tighter interoperability with ZWCAD+,” said Mr. Lee, CEO of New Optics. “When it is time to convert the file formats, the forms retain much greater integrity.”

In addition, ZWCAD+ looks into exactly what their customers use and want, and focuses their features on these needs. This removes redundant features that are not used, to make the whole workflow and interface simple and friendly, as well as to improve the speed of the software.

The Price

The price offered by Nitrosoft, the authorized distributor of ZWCAD+ in Korea, also helped New Optics to reduce expenses and drive up profits. “Using ZWCAD+, we no longer need to worry about expensive purchasing prices or upgrade fees, and I hope more and more companies can have such an enjoyable experience with ZWCAD+,” Mr. Lee added.

4 Reasons Why You Should Not Say No to Mobile CAD

Since the first mobile CAD applications hit the small screens of our PDA’s in the early 90’s, designers have been liberated from their offices, enabling them to take their designs anywhere. Only recently, however, has the quality of consumer mobile devices reached a stage, and therefore extending the reach of these applications to a wider range. With the increased competition between Samsung and Apple in the smart phone and tablet markets, the speed of development has increased dramatically, leading to highly advanced mobile devices. This makes it possible for CAD software developers such as ZWSOFT to produce mobile applications that feature all the tools that users need to make changes and annotations effectively.

Functionality vs. Practicality

Regardless of recent developments in mobile technology, as Ralph Grabowski, Managing Editor of 
Tenlinks.com recently asked in Part 3 of his article “Running CAD on a Small Screen”, why would 
users want to swap the full functionality of their desktop software, with its 15” screen, for limited 
functionality and a 4 inch screen? Well, as Steve Jobs once explained, it is like the small Swiss 
Army Knife carried on a key chain. The most useful tool is the one that we always have with us,
 and it is the portability that Grabowski suggests as the main benefit of CAD on mobile devices.

Design on the Go

The need for designers to work beyond their office is of unparalleled importance in almost any 
other office based profession. Whether it is site visits or product inspections, all designers will, 
at some point, be required to leave their desk and work without their desktop CAD software. 
With mobile CAD software such asZWCAD Touch, designers can now take their designs out of 
the office with them, instead of printing drawings or notes taking the old fashioned way.   
This enables them to make even more accurate examinations of their designs, and annotate directly, 
on the go. Some applications even allow for vocal annotations, such as ZWCAD Touch’s SmartVoice, 
making mobile CAD an even more appealing proposition.

With recent developments in 3G, 4G and even 5G mobile data, users can have their entire design 
portfolio available to them, wherever they are through “the cloud”. With most CAD applications linking
 up to 3^rd party cloud software, this can be done automatically.  Furthermore, with the growing capacity 
of smartphones’ hard drives, high data charges can be avoided by simply loading your drawings directly 
on to your device with even faster speeds.

Greater Productivity at Reduced Costs

Grabowski also suggests that price is a key factor that promotes CAD on mobile devices. Compared to 
the high prices of desktop CAD software, the monthly subscriptions for most mobile CAD software is an 
affordable investment, while some CAD applications, such as ZWCAD Touch, are free to download and 
use.

In addition to the price advantage, companies can also save money by making changes to their design 
process. Money can be saved on reduced printing costs, as designers don’t need to have designs on 
paper when working away from the office. Meanwhile labor costs are also reduced since users don’t 
have to transcribe annotations or alterations, as notes or changes to the drawing on site will automatically
be updated on the desktop version.

Collaborating with ease

Additionally, mobile CAD simplifies procedures and makes more cost efficient, favoring collaboration. 
In the past, users  had to print drawings and present them in person, while they can now email them to 
clients or collaborators, wherever they are. Annotations can then be added and returned to the designer.
 An important factor is that the client or collaborator doesn’t need expensive CAD software, or 
extensive CAD knowledge to view and annotate the drawings, leading to significantly reduced costs of 
collaboration.

In an interview with the Product Manager of ZWCAD Touch from ZWSOFT, Daniel Huang, he 
commented: “CAD on mobile devices may never replace desktop CAD software. Mobile CAD applications,
however, as a supplement to desktop software become truly effective.  With enhanced ease of use 
and cost savings, mobile CAD applications can provide is incredible, and will only improve with new 
mobile technologies.”

Mobile CAD applications have come a long way since their inception in the early 90s, from a mere 
novelty into an absolute necessity. With the development of mobile devices, however, who knows what
surprises will bring to us in the future.

ZWCAD & Hope Technologies Find Success in India

October 31, 2012
ZWSOFT’s exclusive distributor in India, Hope is focused on providing cost-effective CAD solutions to customers in India and internationally. They’ve been partnering with ZWSOFT for over 4 years and because of it, have seen their business grow by leaps and bounds.  Now, Hope has a team of 18 dedicated sales and technical staff while they also appointed and trained 20 channel partners who actively sell ZWSOFT products in India.
 “Our strength is creating the appropriate strategy to enter and sustain the market.” Stated Jacob Panamthanath, CEO of Hope Technologies. Their market journey has been very interesting.

The Indian Market
In India, Autodesk is the dominant player and has more than 80% of the market share. Unlike in other countries where Autodesk has on average 60-65%. Almost all the technical colleges and private training institutes in India only train people in AutoCAD.
Many have tried to introduce different products, but most have failed to make a significant dent in the Indian market due to reliability issues. Because of this, CAD customers are hesitant and not willing to take a risk with new products.
Nevertheless, Hope decided that with the right product, and right strategy, they could be successful.  And that is just what happened.

Hope’s Strategy and Persistence Pays Off
In the first year, Hope pitched ZWCAD as an effective replacement of AutoCAD, and not LT. In order for customers to feel ZWCAD’s power, they created a dedicated team to helps customers transfer their existing LISP programs to ZWCAD.  They also linked existing excel and database applications. This enabled Hope to not only fight only on the price stage, but on ZWCAD’s technical strength as well. In order to effectively spread the word about ZWCAD, Hope did a large number of seminars all across India and targeted a specific market segment which gave them reasonable success.

Over the next 3 years, Hope implemented and experimented with other strategies, trying to find what worked best for ZWCAD in India.  They reached out to over a hundred thousand companies and introduced ZWCAD in over 40 seminars in just one year. During this time, they were hit with an obstacle. The leading CAD provider in India dropped their prices and declared a price war with their competitors.  Hope would not give up, they just worked harder. They did not want to be one of the companies that failed because a large rival pushed them aside.  So Hope strategized and introduced a 3 year subscription plan where customers receive yearly upgrades for a greatly reduced price, while at the same time Hope assured their customers about their long term commitment to them, and ZWCAD.
This plan worked, so Hope decided to open up to the mechanical and plant design market. Because of their mature sales and tech team, they were able to give continuous support and expand their market, even alluring large multi-nationals. Always looking to give added value to their customers, Hope started working with third party developers and developed a few applications themselves.  Education is important and Hope believed in the future generation of CAD students and ZWCAD. Therefore, they began to work with private training institutes, allowing students to train on 2D CAD using ZWCAD.
All of these efforts grew ZWCAD’s name in India and it is now known as a powerful cost-effective 2D CAD solution. Hope has worked tirelessly to spread knowledge about how ZWCAD can not only save users money, but also offer legal CAD software with advanced features that can get the job done.
Happy Customers
One of Hopes customers, the Licensed Engineers and Supervisors Federation (LENSFED) in Kerala, choose ZWCAD for its capability and compatibility of AutoDCR, industry standards and Hope’s outstanding customer support. After purchasing ZWCAD, Hope helped with the set up and installation of the software and was always on hand to provide technical support and answer any questions.


Truman Du, CEO of ZWSOFT stated, “ZWSOFT is proud to have knowledgeable, experienced and helpful local distributors like Hope, all over the world to offer support to our customers, like LENSFED.” Hope tends to go above and beyond for their customers, making sure they are happy and helping in any way they can. This is what makes them and ZWCAD stand out in India’s tough CAD market.

ZWSOFT & Hope, a Successful Partnership

ZWSOFT and Hope went into business together over 4 years ago. Time has flown by and together they’ve managed to accomplish the impossible. Without constant communication, trust and support, things might have turned out differently. “ZWSOFT has always kept their confidence in Hope to grow the business in India, despite the number of resellers approaching them wanting to be a direct partner,” Stated Jacob Panamthanathof Hope Technologies.

Hope has gone above and beyond in their work and partnership with ZWSOFT and because of this, won multiple awards including, partner of the year, great tech support to over 6,000 users and best technical insider.  All of this is a testament to Hope’s commitment to their customers and ZWCAD.

Looking forward, ZWSOFT and Hope plan to expand ZWCAD’s customer base in India. With the recent release of ZWCAD+ with a whole new engine, Hope believes that they will surpass dominant competitors in features, reliability and speed.

ZWCAD+ Takes the User Interface Lead with SmartMouse

Guangzhou, China: October 31, 2012—SmartMouse is a new feature in ZWCAD+ providing command input through mouse movement. Due to the incomparability of SmartMouse technology in the CAD industry, it has been a hit among users and CAD experts alike by providing a whole new UI experience. In order for users to learn more about SmartMouse, the product manager of ZWCAD+ shared design ideas of the feature during a webinar talk, which was well received by the audience.


After the ZWCAD+ official release, the feature first attracted CAD experts to test it. Ralph Grabowski, a renowned author of over 140 books and several hundred magazine articles about computer-aided design, commented on the feature in his recent product review of ZWCAD+: “With the mouse gesturing they call SmartMouse, ZWCAD+ does take the user interface lead over some big-name CAD products. By holding down the right mouse button and dragging the cursor in the shape of a letter of the alphabet (or in a specific directions), I activate a command. Best of all, the SmartMouseConfig command fully customizes any of the movements.”

As SmartMouse gained in popularity, more and more CAD users became interested in the design idea of this new feature. In order to show all the possibilities and explain how SmartMouse works, Daniel Huang the Product Manager of ZWCAD+ hosted a webinar.

“As time progresses, software development has become more and more humanized in user experience. The traditional way for designers to use CAD commands is to type on the keyboard or move the mouse to search for that command button. We think that there can be a different and even better UI experience for users.”

Daniel continued: “With this in mind, we started to research and became inspired by some of the current web browsers. They have similar mouse gesture functions, with which you can trigger certain browsing actions by moving your mouse. We decided to give it a shot in our CAD software. We had some of our users test this feature and they were amazed. Therefore, we spared no effort to perfect it by collecting more suggestions from users and the final design has proven a success. Now a growing number of users worldwide have found this feature a nice time saver after adapting.”

Using Temporary Track point in autocad

Using 'Temporary Track point' in autocad or Zwcad 

Quite a few ex Autocad users may be missing the 'From' snap and the 'Mid2points' snap. Well, the 'from' snap is easy enough (For non-Autocadders: it snaps to a point a relative distance from another point.). 

Let's say for example, you want to start a circle of radius 5mm, '10,25' mm away from the endpoint of existing rectangle:


1. Click on RECTANGLE icon ( or type rec)
2. [Type, as shown in italics, at the comandline] 2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/ <Center of circle >: tt
3. Select temporary track point: <i>click on the selected 'reference' endpoint (of rectangle).
4. 2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/<Center of circle>: @10,25
5. Diameter/<Radius>: 5

PDF definition from Wikipedia:

Portable Document Format (PDF) is a file format used to represent documents in a manner independent of application software, hardware, and operating systems.[1] Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. In 1991, Adobe Systems co-founder John Warnock outlined a system called "Camelot"[2] that evolved into PDF.
While Adobe Systems made the PDF specification available free of charge in 1993, PDF remained a proprietary format, controlled by Adobe, until it was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008.[3][4] In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell and distribute PDF compliant implementations.[5]
