ZWCAD - Version 2020 ZWCAD 2020 is powered by a superior engine to ensure the better .dwg compatibility and code-level API ability. Thanks to multi-core processor, the efficiency has been significantly improved.Its fast. Unprecedentedly.Thanks to multi-core processing technology, the performance of ZWCAD 2020 will not let you down. How fast actually? Some figures in comparison with ZWCAD 2019 may tell: most commonly-used commands and operations: 150% faster on average; opening drawings: 32.4% faster; loading drawings: 73.5% faster.All data you need in one table, at a time.Now with Data Extraction, you can extract various properties and data of an object, and insert them to the current drawing as a table, or export them to an external file in .csv / .xls format. If you need some data in your project for measuring or purchasing, you can acquire them from the drawing conveniently.Manage all your PDF underlays in one dialog box.Now with PDF Underlay Manager in ZWCAD 2020, not only can you check the basic information of each referenced PDF files clearly, but you can also directly open one in PDF reader, easily find where they are located, detach them to make the drawing lighter, etc.Too many Annotation Scales? Reset at once!If youve stored too many annotation scales in a drawing, the performance will be degraded. Now, when opening such kind of drawings, a prompt will pop out to let you reset the Annotation Scale List to its default state by deleting the unneeded ones, ensuring your smooth and efficient design work.Here is good news for developers.Developed based on Visual Studio Code from Microsoft, Lisp Debugger helps check and debug your codes one by one or step by step, to ensure the accuracy of your lisp programs.Clear selection for unclear overlapped objects.By inputting SELECTIONCYCLING and clicking those overlapped objects, a dialog box called Selection Set will appear, in which they will be listed for you to choose the one you really want.
