I have a load of polygons that were originally digitised from CAD. These unfortunately include traingles that were used to sybolise the direction the polygon is facing. As can be seen here:
The trangles are of uniform shape and size and are too numerous to remove manually, so I am trying to automate a sytem that finds them (based of angle and size?) and clips them off the polygons leaving the unsymbolised polygons. I was planing on either doing this using model builder and FME, but I'm no sure which tools/transformations to use. Has anyone got any experience of doing this, and if so how did they go about it and what tools did they use?
