Converting Polyface mesh to a polyline contour

[Anonymous]

Hi everyone,

I am working on a drawing with polyface meshes and I need to extract the contour of each as a polyline.

A sample file is attached. 

Does anyone know how to do it? 

Any help would be very much appreciated!

Thanks,

Calvino

If anyone has come across the issue above. Try the following:-

Try hatching the Polyface Mesh area with a non-solid hatch.

1. Type hatch and select the Polyface Mesh outline

2. Choose a non-solid hatch - Apply/OK

3. Delete the Polyface Mesh outline

4. Type hatchedit and select the hatch

5. Choose re-create boundary - OK.
