Hi - I am new to Rhino. Im a grad student and creating a design for an urban design project. My file has gotten so large its very slow and difficult to work on. Any ways to reduce the size or speed up the process? I already used purge and work with most layers off and in wireframe but its still soooo slow. I am also rendering in VRay and using Lands Design to insert thousands of plants. This is a 4 block area and Im creating ALL elements within it: streets, buildings, seating, lights, bollards, planters, grass, curbs EVERYTHING you see in an urban downtown,

Thank you!

After doing all of the above try
Convert your objects into mesh coz rendering a mesh is faster than nurbs. The file size will become higher but rendering will be fast & smoother. I tried this and it worked for me :)

Hi David,

There are a few things you can do to speed up your workflow with large models.

1. Hide layers that you don't need to see or work with.

2. Avoid Display modes like "rendered", "artistic", "pen", or "ghosted" which work slowlier. The Wireframe one is the faster you can work with.

3. Show One viewport only. The more viewports you are seeing simultaneously, the slowlier the software will perform.

4. Show Lands Design plants in "Conceptual" or "detailed" representation mode. If you chose the "realistic" mode, use the billboards representation. That will improve the model performance considerably.

My 5 cents,
