is there a good script for 3ds import???
its much easier to use a converter like crossroads, milkshape3d, 3d exploration… just save them as DXF and append them into Blender. Also, might want to go into edit mode and remove duplicates.
good luck
For those who are still interested, I did a little search and came up with some links for converting file types:
