I have a triangle of background within my passage (just off a join, but not on it), and am not able to solve it.
I apologize myself - it is not the problem of joining of three scraps. the problem is you divide the wall lines and therion is looking for the nearest point - which makes the triangle. BTW - the orientation of the wall lines is reverse - the yellow tick line should be inside the free space - inside the gallery. The is missing the join command - as opposite to split line command in xtherion. I!ll send you th2 and map file to see the result. There are 2 pictures too to show the problem. If you change the subtype of wall you don't need to start with new line - just continue with another point and change the subtype back to bedrock. In your case: I removed all short walls. Then I added points to wall coming from bottom and replaced those short walls. From the beginning the this line (from the small yellow tick) I added subtypes - 1. point -subtype unsurveyed 2. point -subtype invisible 3. point -subtype unsurveyed 4. point .subtype bedrock And no the triangle there. I only hope it is what you want to draw there. Martin
