Help: Wall Cutting Dynamic Component

Help: Wall Cutting Dynamic Component

Postby juju » Mon Aug 31, 2020 2:15 pm

I put together a dynamic component (SU2020) as a workaround to add additional geometry required when modelling for Construction Documents. I'm having a little trouble getting it to cut cavity walls (multi skin walls it was specifically constructed for).

DC_280cavwall_insert.skp


Anybody here that will take a look at it and guide me where I'm going wrong?

Hi juju,

Had a quick look at your DC. The main component does not seem to have been set to cut an opening (same for the sub components). There are some plugins out there that will cut multiple wall leaves but AFAIK the native SU DC will only cut one face - no matter how many cutting sub-components you build in to the DC. Also, for a window DC you may want to model the DC flat in the XY plane and choose 'Glue to vertical' when creating the finished DC.

Can I point you to an earlier post of mine if it will be of any help.

Apologies if I have missed something in your DC and am talking nonsense!

Thanks for responding. I had a look at your thread previously, thanks.

Yeah, I think I messed up the "glue to vertical" setting, I thought I had selected it but evidently not, any ideas on how to set that after the component creation? I really don't feel like re-doing all the settings again. Component was modeled on the XY plane...

Regarding the cutting of faces, AFAIK cutting of multiple faces can be done as FlexTools has that option. I've just not figured out how they do that.

Select the DC in the Component tray and then right mouse click and select properties. That will let you go for the 'Glue to' and the 'Cut Opening'. I tried this on your DC just now and and you will need to open the DC for editing, select all the sub-components and move them down to the Z=0 position for the vertical 'glue to' to work. At present the back of the whole component will stick to the outside wall face. (try it first after setting the 'glue to'. Also, to cut the outer wall face create a rectangular face (inside the DC) level with the outer wall face. Delete this face to leave just the bounding lines. Do not group these, they form the cutting element. Exit the DC and bring in a fresh DC from the tray - this should now give you the one face opening cut.

Attached modified DC to pick at. I have an updated window to add to my own post shortly.
