relatively self explanatory - have checked, unchecked, restarted, updated and it still doesn’t want to work! using the most recent Rhino version (Windows) - people online seem to not be having trouble at the moment so may need a complete reinstall? would be a hassle - anything else to try (or good plug ins!) that people could recommend?
thanks 
Hi Frederick -
This seems to be working fine here in a simple test. Does this issue also occur on your system in a new file with a simple object such as a shelled box?
Please run the Rhino SystemInfo and copy-paste its output here.
Most settings are kept when uninstalling, so reinstalling almost never fixes anything.
You could use the Reset command to create a copy of your settings (or manually copy the folder to a place where you keep backups of important documents) and then reset to factory settings to see if that makes a difference.

Hi @wim
I had more of a test last night and found out some more, but then couldn’t edit my original post.
The project that the initial screenshot is from is a file with mainly blocks, as it is a model of a housing project so making full house blocks that then maintain edits is the best method for modelling for me. I went into a different file (with no block instances) and the shadows worked perfectly fine - so it must be an issue to do with the house I am cutting through being a singular block instance. I also found that in the same file objects that were not blocks also shadows that ignored clipping planes, but also strangely ghosted behind the clipping plane (image attached). Is this a known issue? or a feature?
coordinates of model if that helps
image showing strange ghosting behind clipping plane
further image showing ‘shadows ignore user defined clipping planes’ not working for either blocks (top houses) or normal objects (block below)
thanks for your time
and here is my SystemInfo
