Here are just a few things you will find in this new version. AViCAD is a perfect solution for those wanting to switch out of AutoCAD (or need CAD) along with Mech-Q.

You can now create your leaders in AViCAD with a variety of arrows, segments, and content, including text and blocks with attributes. Unlike AViCAD’s previous leader objects, MLEADER is a single object that is easy to adjust, with GRIPS.
