Zhongwang CAD+, as the new generation of CAD platform software of Zhongwang, has been greatly improved in function and performance since its introduction in July last year. It has received a lot of user support and praise from the beginning. Of course, at the same time, we have received many requests for improvement and suggestions from users.

While more users are paying attention to the software front-end experience, as a CAD engineer who has experienced and witnessed the birth and growth of CAD+, we have been adhering to the “user-centric” attitude to treat every improvement and upgrade. We know that a new CAD product as a new kernel will not be perfect in the beginning. It is these flaws that encourage us to continuously upgrade and improve to provide a better user experience and product quality, and better meet the needs of designers.

In the past 12 months, Zhongwang CAD+ has released several patch update packages and two large SP upgrades. In these upgrades, in addition to solving the bugs in the software , many new features have been added to bring new experiences to users. Since these upgrades and updates are part of the same annual version, users who have purchased the Zhongwang CAD+2012 version can enjoy these large and timely value-added services for free without additional payment. In fact, according to the international software version update convention, the update package inside the large annual version is only a problem fix, and will not provide new features. Zhongwang chooses such an upgrade method, which is undoubtedly more user-considered: we always hope to solve and reflect the needs of users in the first time, and quickly increase the product capability without giving the user extra cost. It is more in line with the habits of Chinese users and has an incomparable local advantage.

Just take Zhongwang CAD+2012 SP2 as an example. The highlights are remarkable, and of course, it has been widely praised by users.

In the Zhongwang CAD+ 2012SP2 update, the raster image insertion function and the filling function have been improved, modified and updated. In terms of raster image, the old image engine is relatively old due to its old mechanism and advanced technology. Therefore, it is more difficult to process large pictures and large pictures (such as image files of 1GB or more), mainly because the panning speed is slow and the picture display quality is not good. higher. It leads to users being less efficient when using large images and the experience is not good enough. On the basis of a large number of user feedback, Zhongwang CAD+ made a major transformation of the image engine, allowing it to change its face and adapt to more advanced and complex applications. In SP2, we applied this new image engine technology, which has the following characteristics:

First, a new image caching mechanism. When inserting a picture for the first time, Zhongwang CAD+ will automatically create its corresponding image cache file in the hard disk cache folder. The data in this cache file exists in the form of a pyramid for a long time, and will be automatically read each time the picture is used. Take the pyramid data of the corresponding level in this cache. Since the data is already pre-stored, the subsequent insertion and use (such as panning and zooming) will become very fast and the efficiency will be greatly improved. And because these data are long-lived in the hard disk, so once generated, lifelong use, can be described as once and for all. If you are lucky enough to use SSD solid state hard disk as the system disk (image buffer disk), you can feel the processing speed of Zhongwang CAD+ flying.

Second, a convenient image cache batch creation tool. In order to make better use of the above image caching mechanism, in addition to automatically creating a cache by Zhongwang CAD+ when inserting a picture for the first time, we also provide a tool specifically for batch generation of cache files. Users can batch-generate corresponding cache files by using this tool in advance, then use these images instead of temporary processing, and directly read the generated cache data. This tool can be found through the system "Start" menu - Zhongwang CAD+ - utility.

Third, high-performance image display technology. The new engine is superior in image display processing, which can make full use of the performance of the graphics card GPU, and improve the display quality and speed in essence through the block display and split screen display technology.

Fourth, the new engine solves a large number of image-related problems in the past and implements support for transparent background images. Designers who often use raster images should know that there are some PNG, TIF-like multi-color or monochrome bitmaps whose background is transparent, which cannot be reflected in the previous CAD+ version. The release of SP2 is a good solution to this need, these images can be set to a transparent background through the property bar.

In addition, Zhongwang CAD+SP2 version also complements the filling function, and realizes the functions of filling boundary editing, creating independent filling and dynamic preview. In particular, dynamic preview is very easy to use, allowing users to directly see the actual effect of the fill in the drawing area without closing the dialog box when creating the fill, and dynamically change as the settings change, WYSIWYG. This is another manifestation of Zhongwang CAD+'s attention to user experience.

At the same time, the addition of many new functions such as drawing anti-modification, drawing recovery manager, JOIN, FLLATEN, and selection of similar objects makes the improvement of Zhongwang CAD+SP2 comparable to a large annual version. Upgrade is very worthy of the upgrade experience of designers.

In the year since the release of Zhongwang CAD+2012, users have given us tremendous support and help. Whether it is praise or criticism, it has made this new product complete a very fast iteration in just one year. Updated to grow into a mature CAD platform for greater reliability and practicality.

In September 2013, Zhongwang CAD+2014 will be officially released. This version upgrade will include extremely rich new features and experience improvements, both for users and for ourselves. At present, the Beta test version of Zhongwang CAD+2014 has been released, and the test contest is also underway. Welcome CAD users to actively participate and give us valuable opinions.
