---- Version 4.01 -----:
- 4 small bugs were corrected.
- Cd-H is not used any more by RealCADD and thus is available to mask RealCADD under Mac OS X.
- The sight and the zoom are stored at the time of the backup of a file.
- When one zooms with the mouse's wheel, the position of the mouse definite the center of the zoom.
- New menu "Convert" in "File" allowing to convert into DWG (version Pro) all the files RealCADD present in a folder.
- Attraction on "Alignments": i.e. on 1 or 2 points which you indicate to RealCADD. On the image below, with the tool "Line" and attractions "End" and "Center" active, the high-left end and the center of the line were approached to have attraction on them. Then if the cursor is sufficiently close to alignment with one or the other to these 2 points, attraction is activated. Here attraction on the 2 points was found the beginning of the line will thus be aligned on the 2 predefined points. With the long crosshair displayed, alignments are more visible.
