Sterelithography
Sterelithography
(OP)
On the advice of someone in the AutoCAD section i started working with the Rhino demo and my boss is going to buy it for me now. Thanks for the tip
Quick question. With the stereolithography output, is there a way to test the validity of the file to determine if the STL output is successful? It creates the files easy enough but I can't figure out if it is a valid model or not?
Thanks

RE: Sterelithography
Check an object for geeky relationships in geometry data structures.
Toolbar: Analyze, Diagnostics, and Geometry Fix
Menu: Analyze > Diagnostics > Check
Command: Check
At the Select object to check prompt, select one object.
A report on the correctness of the object shows on the command line. Use CommandHistory or press F2 to view.
This is primarily a tool for diagnosing potential geometry bugs.
Note
Delete or rebuild the object.
----------
ShowBrokenEdges
Display broken edges.
Toolbar: Diagnostics
Menu: Analyze > Diagnostics > Show Broken Edges
Command: ShowBrokenEdges
At the Select surfaces or polysurfaces for broken edge display prompt, select objects and press Enter.
Broken edges show in the selected objects color, or "Found 0 edges with problems" appears at the command line.
The edge is highlighted, and point blips are drawn at the edge's endpoints so you can see the edges even if the edge itself is microscopic.

There are Rhino tools you can use to examine your model for these defects.
The first one to try is the Check command. If your model doesn't pass Check, then it will list some specific problems. You can just use the list to indicate that you might need to tune up the model. If a model passes Check, it doesn't automatically mean that it is 100% properly structured, though. Some bad model parts, like having surfaces that fold back on themselves or self-intersect, are very time consuming and difficult to automatically detect, and Check doesn't check for those things. But it can check the general overall structure of the object.
If your model doesn't pass Check, then you can use the ShowBrokenEdges command to highlight which specific edges are not passing Check.
To fix broken edges, you have to explode the model, then use Untrim or DetachTrim to remove the trimming information from the problem areas, then edit the trim curves, re-trim the surface, and join everything back together again.
Hope this is useful.
