Question

I have been getting some files which are growing to an unwieldy size, despite not intentionally having huge amounts of information, or being large buildings. One in particular has grown to 473MB and struggles with crashing when rendering in Open GL, or creating new section viewports!! Obviously I can't upload it for tech to look at as there is a file size limit. Any users had similar issues and found a glaring settings change that can be made to shrink the files. I have asked if a future webinar can cover this subject but in the mean time.... heres hoping

do you have a lot of mesh items in your file.  these will balloon file size incredibly.  if you have imported items from sketchup or other programs into your drawing check those.  they may be small sized in their native format, but get much larger in VW.

Another thing to check would be the Tools menu: Purge.. command to make sure you are not carrying around a bunch of images or textures that are not being used.

 

Depending on how complex the file is, 400Gig is not unheard of.

 

Are you using Symbols rather than duplicates of objects where possible?

 

Have you brought in PDF or other image files?

Rendered viewports are effectively bitmaps saved in the file, so that could definitely impact the file size if you have a lot of them. Especially if they are high resolution.

 

Glad you found the issue.
