dormers

[michael john williams]

Dormers can be a pain!

But trying to do a simple dormer with the main roof with an overhang of say 300mm and the dormer hip roof overhangs say 300mm to line in with the main roof and the face of the dormer is inline with the wall. End up with the overhang of the main roof going over and in front of the dormer - it does not cut back.

Any suggestions would be welcome.

Try converting the roof to a group and editing the roof face to trim out the bit under the dormer.

thanks for the quick response - i've had a go at this and the cutting out of the section of roof seems to work ok, but then when i switch to my perspective viewport the roof is missing. the roof layer and class are turned on so i can't understand the problem.

Did you reassign the class when you ungrouped? Go through the layers and classes with active only on (Control key, up and down arrows, or, side to side arrows)to isolate geometry. What is likely to have happened us you inadvertantly reassigned the objects to a different class or layer and this class or layer is switched off in your viewport.
