Shards of some time space continuum? What are they trying to tell me and how do I get rid of them? Troubling little tribbles. Thanks!
I think they might indicate a few points that are not on the same plane as all the other points around the edge for which you have generated a face. Probably from manually adding the segments of the circular polygons and slightly mis-aligning them (?). By hiding what you have added, regenerating that face, then unhiding what you have added, you might be able to see what is misaligned. At that point you could select all and "interface with selection" then delete anything protruding from the newly generated face.
Or you have tribbles. In which case you're screwed and should find another planet to explore ...
HTH
Thanks Matt. Yeah, I figured it was something like that but I couldn't figure a way to get rid of them. It seems like some of the Fix It plugins cause those. Hell, if I run my part through NetFabb (local, not online), then Repair, it comes out looking like a pineapple cactus, covered with shards.
But, I am learning a lot thanks to you guys.
If you want to post the SU file, I'll take a quick look. Have you tried the "CleanUp" plugin in SU?
SuSolid is good for analysis, but every time I use CleanUp or, more so, Solidsolver, I get the shards AND it takes a perfectly good line and converts it into two or ten or three, whatever, smaller intersected lines (!?) or deletes a section of it altogether. It seems like some utilities try to make connections that I never intended and thus screw up good objects.
I think I need a shard remover. I there anything like a Shard Not or Shard B Gone? Shard Away? ShardTastic?
Here, is what I mean attached

These are flipped faces, and sketchup has a tendency to do them, particularly when moving an intersection with multiple planes or near a circle.
If you right click them, select reverse faces, they go back to being correctly orientated.
Now - the hows or whys regarding SketchUp doing this is a mystery, but this is one of its 'quirks'.
2013 handles it better than 8, but its still far from perfect in this aspect. Its the 'smarts' of SketchUp that help you in lots of other areas getting confused - because of the way it breaks down planes and vertices, it can get confused about whats the interior and exterior, try to help you by flipping faces, and in fact making the whole situation worse. This is why 8 makes a complete mess when it needs to create additional vertices (since there is no 'curves' in sketchup... )
But at least with 2013, I've found you can move more stuff near multi-vertices than you can otherwise.
Thank you, Adrian! Is there a tip and tricks listing somewhere with oh-by-the-way stuff like this? I feel bad having to keep asking for help but I work many hours trying to figure things out, and often do. There is no substitute for experience, eh?
I should receive my Dummies book today, maybe it will help. Thanks again, pal.
