View Full Version : Program hangs when meshing
10-13-2011, 08:19 PM
I have attached a file, that if I try to preview the mesh, will cause Groboto to go into infinite figure-figure. It hangs. It is repeatable on my computer, a Win 7 Home Premium with a 6 core AMD, 8 gigs RAM, NVIDIA 8400 video card. Could someone try previewing it and let me know if it is the file, or my computer?

You have a cylinder that is not part of the cluster, when you try a mesh the object Gtoboto hangs. If you delete that cylinder the object meshes quickly. I added the cylinder to the cluster and it meshes without hanging.

I've tried a few different things with your model and the mesh isn't very clean when you add the second cylinder to the cluster. I tried modeling the object in a couple of different ways and it still hangs when meshing.

Yea, I'm still having trouble with it. Leave it to a newbie to cause trouble! :) Is there a way to specify that some edges are smoothed to different degrees? I want a box with very rounded edges, but not so rounded top and bottom, kind of like this;
I was just using the cylinders to make the round corners.

Groboto might not be the best solution for this type of object. You can round the edges of a box in the mesh menu, but you can't specify individual edges as they all get rounded the same.

Yes, it hangs because of the second cylinder (right-hand in the pic below). While we fix this bug, there's an easy workaround. We just need to renumber the objects. In the original file the sequence is this:
0. Big main box
1. Cylinder on the left
2,3,4. Three thin slabs (selected in the pic below)
5. Cylinder on the right
What we need is place the three slabs at the end of the sequence. To do this select all three, choose Edit->Cut Selected Objects, then Edit->Paste Selected Objects in Place. The newly pasted objects are added to the end of object list.
Btw, I noticed when selecting objects that they are arranged into boolean clusters (a simple click with the Select tool selects all the objects in a cluster). The clusters do not play any useful function in this file as it is, since there are no boolean trims. Maybe the trims were to be added later? In any case, individual objects can still be selected when they are members of a cluster, by holding Alt when using the Select tool.
And another little thing: the right-hand cylinder's radius should be increased very slightly, so that it protrudes beyond the flat surface of the right-hand slab. The way it is now it is sunk below the slab surface, which creates a thin ledge in the mesh.

This what I got by rounding all the edges in the mesh (as David mentioned, we don't have edge-specific settings at this time, though this is going to happen very soon). And I kept your cylinders to get much greater rounding on the two vertical edges:
Here's the gbr (http://www.braid.com/boris/Forum/Intercom Box-fix.zip) file with these settings.

Lots of new info for me there. I need to study up on the cluster use and how to make them. I wasn't planning on adding trims later. The main purpose of this model is for me to learn with, so it is serving its function well. I am having to adapt my CAD solids drawing background somewhat with the different approach here. But for me it sure beats having to learn something completely foreign like subdivision modeling.
Great support here!
