I have seen this posted on this forum, but there was no answer. I am using AutoCad Civil 3D 2012, with windows XP, and when I type "extrim" at the command line, I get this:
"bad argument type: listp #<SUBR @2f9669b0 BONUS_ERROR>"
There are also a few other express tools that when picked from the ribbon menu, do not work either. Now, I have seen elsewhere on the web that in this case, you should make sure there are no search paths set to R14 Bonus tools (which mine aren't), or repair and update express tools from add/remove programs in the control panel. I did this, and the only thing that happened was the numbers after SUBR@ changed. Does anyone know why this is happening? Does anyone have a solution?
