Hi Kent, I created a sheet metal panel in Autocad before I purchased
Inventor. I am trying to create a sheet metal part in Inventor 6. The
Autocad part was dimensioned, using the Ordinate Dimension system. The X and
Y datum's were located at a hole on the part. I located that same hole at
0,0 on the sketch grid when creating the Base Sketch. I did this, so I could
use the same dimensions that are on the Autocad drawing. But after creating
the base sketch using the Features Panel and returning to Sketch Mode, the
0,0 location on the sketch grid is located at the lower left corner of the
base sketch. Because of this, I can not place the other holes on the panel,
using that datum point. I had no problem placing the addition holes on the
base sketch, but I could not add the hole features using that sketch.
Because the 0,0 location changed, I have to re-calculate the dimensions to
the holes from that 0,0 position. Bob
