At my corporation we use mechanical desktop for some of our complex shapes/ forms. We are going through the painful process in upgrading from 2008 to 2010 (painful because Mechanical Desktop is going away). With this upgrade we are losing some functions that were in Mechanical Desktop which we cannot find in AutoCAD or AutoCAD Mechanical. I know what you are thinking, why not transition to Inventor? Well, we do not have the budget or training time to convert all designers (80+) to Inventor, plus update all our processes. Below are commands we would like to find replacements for inside AutoCAD or AutoCAD Mechanical:

Intersect – Trim
Lengthen to Surface
Surface Stitching
Offset Surface
Edit Solid

Any help is appreciated, Thanks.
