OTB Idea #13: Slow rendering models
-
Chuck: Sometimes updating a model takes twice or three times as long as usual, as if there was a memory suck going on somewhere. I usually have to close Layout and restart a few times a day to keep this under control.
Barry: Are you vector rendering? Vector rendering re-renders the entire model. We suggest working in low resolution raster until you're ready for final output. If not, respond back, and we'll look at what else it could be.
Chuck: Haha, you got me on this one. I am rendering in vector. It's too bad that my beast of a computer (8 3.2 gig processors and 10 gig of ram) has it's hands tied by the lack of multithreading for rendering. If I change the render style to medium or low raster, do I have to change each instance, or is a change to one instance applied globally? I have the render quality set to medium in preferences.
Barry: I worked a bit on a model with Dave R and talked to him at 3D Basecamp. We're still trying to learn what it is that makes vector rendering in LO / PDF export in SU (yes, same vector export) slow at times besides just having to render the entire model.
Yes, you do have to change each view, one by one. Have coffee nearby, it could be slow getting them changed back to raster. And give yourself adequate time to convert back to vector before exporting / printing.

Barry,
Do you think there'd be any improvement in speed if all of the model was contained in a smaller space?
I'm thinking of my models where I have an assembled version and an exploded version. For a table I would set up layers for the top, legs, aprons, etc. All copies of the leg components would be on the 'Legs' layer.
If I made layers such as "Legs" and "Legs,exploded view", "Aprons" and Aprons, exploded view" I could keep them in the same general area and switch between those layers for the assembled and exploded views of the table. Or if I only have layers for the exploded views on and all the rest off, perhaps it wouldn't matter where in the drawing space they are located? Do these ideas seem like something that would reduce render times?

I don't think it can hurt. Not knowing the full extent of why it takes longer like Jeff does, I can't guarantee it.
