Trouble Shooting in AutoCAD
Once you are satisfied with the
of the rectification and you close ASRix to return to AutoCAD one of two things will
One error you might encounter is
the image being inserted on the wrong plane.
- The image will appear on the correct plane with the measured points accurately
their corresponding AutoCAD entities
- It won't
This happens when the coordinate system in which you took your measurements for
rectification is not the same as that of your drawing. Make sure your drawing is in the
World Coordinate System
when you insert an image but, if that doesn't work you can force things by using
select the points. The
command is the easiest way to do this once the points have been placed on the image.
Small Errors in alignment are usually the result of:
- The points selected not being on a true plane
Sometimes you can improve things by using different
to define the rectification plane. If that doesn't help, by eliminating the points that
most from the plane defined.
- Poorly placed points in the image
Detach the image, refine your point placement in ASRix and reinsert using the
- Poorly measured points
Usually its too late to do anything about that.
