DMclean Posted November 20, 2014 Share Posted November 20, 2014 Have the object on the left which will not allow me to push/pull any of its faces. Checking with object doctor reveals nothing, don't seem to be any errant points that I can find, info says it's a solid... Extruded one of the end plates to create the copy on the right. This would allow my to push/pull the faces which I did, moving the purple face to be co-planar with the gray face. Keep edges was OFF, so the two faces should have merged but did not. Ran Object doctor which reports that it has fixed One Zero Area Face/Hole and 1 Missing face. Object now will not push/pull. Object Doctor just repeatedly reports the same fix over and over but nothing changes. Model attached... Curious about what is wrong with the shape.

Tech Posted November 20, 2014 Share Posted November 20, 2014 Hi Doug, The Object Doctor finds a zero area hole in this object (using the Add to Selection option): If you just Move the colored face up, it should then "fix" it... Link to comment Share on other sites More sharing options...
DMclean Posted November 20, 2014 Author Share Posted November 20, 2014 What I'm trying to do is have the Purple face merge with the grey face, and every way I attempt that seems to generate bad geometry. There must be something fundamentally wrong with object, but I can't find it. I should be able to just push/pull one of the faces planar to the other and the faces should just merge. I do that all the time, but for some reason this object won't do it. Doug Link to comment Share on other sites More sharing options...
Tech Posted November 20, 2014 Share Posted November 20, 2014 Hi Doug, I am not sure what you did to it, but it was pretty easy to fix it by just deleting the unwanted segments, and Fixing the Collinear Points (with the Object Doctor).

DMclean Posted November 20, 2014 Author Share Posted November 20, 2014 Opened your fixed object on my machine. Chose the large merged grey plane and pulled it up. No Problem. Then pushed it back down. When the face pushed down it left an unwanted segment on the perpendicular face which it normally does not do. Also, If I push the face downward s few times, I don't get more segments on the face, but it does leave behind points. The object which started with18 Faces, 18 Outlines, 48 Edges, 32 Points now has 19 Faces, 19 Outlines, 56 Edges, and 39 Points. Odd. Doug Link to comment Share on other sites More sharing options...
DMclean Posted November 20, 2014 Author Share Posted November 20, 2014 I can easily get and fix the object to a point that I think it is fine, but when I do a number of other operations, something usually goes wrong, especially Booleans. Additions of it to another object which is basically a copy of itself inevitably leads me to an object with leftover facets and points.

Tech Posted November 20, 2014 Share Posted November 20, 2014 Hi Doug, Ok, I see the problem. These shapes have very very slightly non-planar faces, which you can see if you scale the objects up 1000 times and then Triangulate with the Strict Planarity option... Project the end face to make it Flat, and then re-extrude and it should work better for you... Link to comment Share on other sites More sharing options...
DMclean Posted November 20, 2014 Author Share Posted November 20, 2014 I thought that might be where the problem lay, but I kept checking planarity (even with strict planarity set) and nothing was being shown as non planar. I tried at one point to just transform and scale down to 0 on one dimension, but the transform controller would only let me get down to 1/16" which is probably the degree of accuracy that I have set in preferences. Always forget about Projecting the face. The scaling up huge is a good trick to remember for checking planarity. Thanks, Doug Link to comment Share on other sites More sharing options...
