3D Rendering for large models freezes
I'm using the Mac version and have 30Gb assigned to SW3D. I work on very large, detailed models and cannot use the 'view all levels' feature for 3d view as it freezes or hangs the application entirely.
Is this a limitation because of the size of the models or is there anything I can do to speed things up please?

Re: 3D Rendering for large models freezes
I suspect it's not freezing but just waiting for the 3D view to finish rendering. I have seen waiting times of 30 minutes with very large and detailed projects. It's because the 3D view rendering commands are stacked meaning that even if you change something a new rendering is executed but the previous rendering is first completed before the next where your change is rendered. Do that a few times and there's a rendering queue that takes a lot of time. The worst is that even if you close your project the rendering queue remains active in the background until it's finished although there's nowhere to display the results. Fortunately you can often save the project between rederings and then just kill the proces. Remove the 'work' directory from the .eteks directory and you can start fresh.
The new beta version of Sweet Home 3D has the new functionality where collapsing the 3D View stops adding new 3D view renderings. That way you can make multiple changes in your 2D plan and expand the 3D view to get it rendered once without a whole queue of useless previous redenderings to execute.
