Trim Wall

[Anonymous]

So - again, bare with me here I have just upgraded from v.13 to 17, so I am probably missing a lot of new tools and how to use them by jumping so many versions. If my questions seem lame - this is why.

In 13 the Trim to roof tool was handy because you could trim a wall to a roof and then move the roof or delete it and still hold that edited shape of the wall.

In 17 - it seems that this is not the case with the trim to roof or shell tool any more. When you move or raise the roof the wall shape changes with it.

Is this all true?
Do we not anymore have that old trim to roof option?

The old static "trim" is now called "crop"

So we can no longer trim a wall to roof... then delete the roof and have a trimmed wall..

Yes you can so long as you 'Crop' your roof.
This is the equivalent of the old 'Trim' command.
You must also convert any multi-plane roofs to single roof planes.
So exactly the same as old versions except the name has changed from 'Trim' to 'Crop'.

'Trim' now performs a kind of Solid Element Operation on the wall and the roof must remain in the model for the trim to stay active.
The only differences between Trim and SEO is that with trim you graphically choose the upward or downward extrusion and any part of the wall outside of the roofs trimming body will be cut away (in 3D - still not in 2D).
The SEO doesn't use the roof trimming body so literally only the part of the wall interacting with the roof is cut - any part of the wall outside the roof will remain (in 3D).
