1. Memory Optimization

You’ll work faster and more efficiently because the Memory Optimization with compressed processing and new optimized arithmetic improves the efficiency of commonly-used commands and reduces CPU usage and memory, resulting in greater speed and stability, especially when of dealing with large drawings.

2. Improved Function: In - Place Text Editor

ZWCAD 2010’s newly-developed In-Place MTEXT Editor will help you focus on your design and make your work experience more efficient with new and improved functions for your convenience.

3. Enhanced Application Programming Interfaces

Also in ZWCAD 2010 Beta, APIs like Lisp and VBA have been greatly enhanced, with 13 new functions added to the Lisp Vlax and Vlr series. ZWSOFT has added new commands to VBA as well, such as AppendOuterLoop and AppendInnerLoop to increase your proficiency. Another highlight of ZWCAD 2010 Beta APIs is the introduction of ZWSOFT's own runtime extension, ZRX.
