Section viewport INCREDIBLY SLOW 2020 WHY!? Beyond cut plane

[zoeageorg 4]

I am getting so fed up of vectorworks being impossibly slow whenever i cut a section and want to display the objects beyond the cut plane. If i use hidden line, or turn up the sheet layer DPI or open gl quality

 

Ive attached one of my files if anyone wants to try looking

I would imagine that some or most of the slowness may be caused by your project being so far from origin (0,0). See below.

 

 

Try correcting this and then see how performance of the file is.

 

Also, it looks like a DWG file may have been imported directly into you Vectorworks file. (Since I never know how other people create their DWG files, I prefer to not bring their objects into my otherwise healthy Vectorworks files.) Instead it is advisable to not import DWG files directly into your Vectorworks file but rather to import them into a "shuttle" file that can then be either be cleaned up for import into your Vectorworks file or saved as a Vectorworks file of its own to then reference into you Vectorworks file.

Thanks very much I shall have a look at these!

@Neil Barman i have 'set user origin to internal origin'

should that do the trick?

[Neil Barman 153]

@zoeageorg It should certainly help. Give it a try and see what your results are. It's always a good idea to work close to origin.

 

If the file is still having performance issues I would recommend auditing it for problematic or overly complex items that may have come in with the DWG file. If you don't need any of those complex items it would be best to delete them. If you do need them but they are still overly complex, it would work worth simplifying them or replacing them with native-built Vectorworks objects.

@zoeageorg Please let us know if you need any further assistance with your Vectorworks file. If the file is still causing you issues after Neil's advice, please send us an email through to uktech@vectorworks.net and we would be happy to help.

Try tools-origin- centre drawing on internal origin. Other things to check would be extents before and beyond cut plane. Get in touch with Uk tech if you need further assistance.

Hi @zoeageorg, I encounter users with this situation a lot. So often I've created linear instructions for users to correct what I call, 'far out objects.' I'll attach this for you below.

 

I'd like to add to @Neil Barman's comment about complex objects. Even one object - if geometrically complex enough - can have a big impact on certain operations such as rending in Hidden Line. Also, my tests indicate that objects that are cropped out of a Viewport are still part of the calculations performed, which can make rendering times seem disproportionate, but that's the way they have to be done. You can improve this situation though by moving objects outside your crop to another Design Layer or to a Class not featured in the Viewport - but maybe only do that if it suits your workflow/layout needs to do so.
