tground
Description
Prepares to round off the joints of graphic lines. When a selected graphic line handle is clicked, the joint at that point will be rounded off. PTC ALD actually inserts bicubic curve control points into the line so that the radius of the curve will be the current rounding radius, see tgrrad for further information. This macro forms one part of a 4 step process required to round off the corners of a box:
1. Convert the corner to a line with tgmkline
2. Set the rounding radius of the resulting line (default 10mm)
3. Enter the rounding mode using this tground macro
4. Click on the corners of the box that you wish to be rounded
