Does anyone know the best workflow to create drawings with cutaways like the images attached? It would be greatly appreciated.
Hi Sasha -
The only non-destructive way to create such cutaways is by using the clipping plane feature. These are flat planes only, at this point. The alternative would be to actually cut the geometry and delete or hide what’s not needed.

Hi Wim,
oh right thanks so much, do you think the team will implement a command which can allow you to do this in a non-destructive way later down the line or it’s not a priority?
Hi Sasha -
It’s not a priority at this point, but it’s on the list. I’ve added one of your pictures to the feature request - item RH-3952.
Thanks,

VisualArq can do ‘live booleans’, meaning you can cut objects with any closed brep, and edit both afterwards.
If you want to transform the cutter after the boolean you can simply turn on control points for the object that was cut, and the cutter object will be shown with dashed lines, and you can move it. To change the cutter’s shape, you need to extract it, edit it, then Boolean again.
However, the objects to cut have to be of a VA type, but you can convert any closed brep, no matter the shape, to a VA wall, then it works.
The plugin is not free, though. You could mess with Grasshopper, too, to get a parametric workflow, but it would be somewhat less convenient, because you would have to bake the result after every change.

Oh right i see thank you for this suggestion!
hi Sasha, why not using the classic approach to this, nowadays everybody wants to have it automatic and parametric and and and, your example is a perfect example for how this stuff was done manually with a little composition. simply render the scene out twice overlay and close up in photoshop before you search for days for a different method. if the background changes you still can use the overlays. or draw a curve with polyline on mesh or snap option surface onto the outer shell and cut it out which is probably even the fasted method. in this example you would have your result in less than 5 minutes of course depending on your actual model. to copy the wall and hide would be 3 seconds, so dont be afraid to get your hands dirty

Hi, thanks so much didn’t think about this and I think this might be my solution! I’m trying to improve my technical abilities and this sounds like a good way to go about it thanks again!
