color=#0000ff size=2>I believe the -I option to rtrace automatically takes the
trace point one unit in front of the point to avoid conflict with a surface (in
case your point is defined co-planar with a wall, floor, etc.). This would
probably be fine if you model was set up in inches or mm. Maybe you can scale
your model to millimeters using xform -s?</FONT></SPAN></DIV>

question to the list, would the -i (lowercase) be appropriate to get the value
for the exact point as defined?</FONT></SPAN></DIV>
