I've tried the 3 attatching methods: Merge Edge Tool, Merge Multiple Edges Tool and Merge Vertices. 1_Geometry before I start The 2 Merge Edge tool options don't seem to work properly at all, see attached 2 - 3.2 2_Merge Multiple edges 3.1_Merge Edges 3.2_Merge Edges (I cant select a 2nd edge on the jaw) You should be able to use the merge vertices option. Just make sure you delete the faces where you are merging. And make sure you have combined (polygons>Combine) the two objects together to become one. Originally posted by wr_uk 4_Merged Vertices... seems to work OK until you look where its been attached there is a thick line which normally indicates an edge. Is this correct? I have a feeling there is somthing wrong with this geometry as these operations work ok with simple surfaces 5_Merge Edges Thick Line Also is there any way to view "thick lines that indicate the edge on surfaces" with out slecting the merge edge tool? Wayne The thicker edge lines are a display setting under preferences (not shown in the tutorial). It is under the polygon display settings. I can't remember the actual option since I am not on my home machine, but you could set a numerical value for how thick you wanted it. Remember that if you change something and don't like it you can always reset the preferences to their default.
