Title: Faster Support Generation
Post by: mitchfx on November 22, 2017, 07:46:54 PM
Are there any plans to optimize the generation of supports for complicated models?  I really like experimenting with them for organic objects to be printed on my FDM units, but most of my models are over 1 million polys which really slows down the supports creation.  I often have to wait 5 minutes or more each time I make a change and re-generate them, which makes fine tuning things very painful.  What might be cool is to have an option to create/use a decimated proxy of heavy objects that would be used for the supports calculations but then swapped back out for the orginal high-res model upon export or sending to printer.

You might try this:

- Create a duplicate of your highres object. Hide your highres object.
- Decimate your duplicate object
- Create supports on that reduced duplicate
- That done go to SELECT, select the reduced object's surface and discard it so only supports remain
- Show your highness object and combine it with the supports.

- Doing this you'll see MM treating the supports as standard objects running Overhangs once again;
- Be careful while reducing. Reducing too much might result in intersection between supports and highness object finally.

Thank you for your suggestion. You are asking for a complex feature that is not likely to appear in a free product in the nearest future.
For now you might have to experiment with other Autodesk products, like Netfabb or Fusion.
