Change log

CCAD8.3 new functions

1. A new process bar for opening and saving dcc/dwg large images has been added in the lower left corner of the screen.

2. The speed of opening DCC/DWG large and very large pictures has been increased by 50%, and the speed of copying/moving/rotating large and very large pictures has been increased several times.

3. The data capacity of a single dcc/dwg image is increased: the designer software is increased to 300,000, the super engineer software is increased to 2 million; the dwg layer processing capacity is increased to 1,000 layers.

4. Added support for dwg/dxf files of AutoCAD 2013 - AutoCAD 2015

5. Added significant labels to invisible tiny discrete graphics in DWG drawings. When discrete graphics are found, the drawing automatically enters the effective area extraction operation state.

6. The dwg export option adds a font substitution column. The default substitution font is Song Dynasty, which can avoid the text becoming a '?' sign due to the lack of imitation Song Dynasty when opening in AutoCAD.

7. The default export format of dxf is changed to ASCII format to facilitate CNC equipment users.

8. The image export function is added to the PDF file, and the line width control is added to the export, making the exported PDF file more beautiful.

9. Replaced the old GB2312 faux Song and Kai fonts under Windows.

10. Corrected the problem of incomplete mirror images of individual annotations.

11. The block base point switch is changed to off by default. When inserting blocks/libraries/images, the CAD menu on the right automatically changes to the block menu, which facilitates scaling and rotating blocks.

12. Eliminated the phenomenon of occasional residual screen graphics and diagonal flickering when redrawing.

13. Eliminated the phenomenon of cursor flickering and inaccurate point capture caused when the word picking switch on the Kingsoft PowerWord screen is turned on.

14. Added a new management function for commonly used Chinese input methods: Chinese input is automatically turned off during drawing, coordinate input, calculation, etc., eliminating the interference of input methods on letter menus, coordinate input and other operations.

15. The folder in the management area can be expanded by double-clicking instead of expanding by clicking.
