Auto Dimensions between polyline and a proposed line


Recommended Posts

I have a problem...

I need to make a routine for myself and my co-workers.. ok here is the situation.

We will have a polyline created from a series of points, where we need to plot dimensions perpendicular to the proposed line stating the difference between the proposed and existing.


It is something like this:



An auto dimension lisp will help us a lot as we will have lots of dimensions in our daily routine.
Thanks a lot in advance...

I made something.


But you do need to

- either make the red polyline 1 closed polyline

- or cut the grey polyline in single side polylines.

The grey and red polylines mush match one to one.


See my upload as example.

Option 1 will cause problems in the corners.  Option 2 is probably more preferred.


- command ADBP, for Auto Dimensions Between Polylines

- select grey polyline, then select red polyline.

(first set the layer to whatever layer you want the dimensions to be drawn on)
