How to incline a plane for eg a roof

baumar

Hi, 

I'm trying to incline a plane for a roof. I tried to use draft, but it didn't work. I think I saw this in a video in one of the many steps, but I can't find it again.
 
For ease of description I created a small example under https://cad.onshape.com/documents/ebb05669046446eea2043a7b/w/6db80791788eda8622f33b5f/e/555ad30ddb93176925c61dd9
There is a pound in the middle (for demo purpose it is solid) and I would like to incline the plate to the right and the left so they would lay on the pound. 

Thanks for help

Hi Bruce, yes it does help, I can now rotate an element. What I could not manage properly is the following: if the part refers to a base plane, then I have to stretch the element. I have to fix a line and define a line or point to where it should be stretched. It's a bit difficult to describe, but I found an good example: create a pyramid from a base plane to a given peak point, as I sketched in Pyramid https://cad.onshape.com/documents/294778f0f2aa9b816d4bccca/w/a87bbbd68e49f2f904fb13c9/e/ad9abb1ee3b6ca4b82398cf7



To create the faces of the pyramid, the outer line has to remain constant, whereas the other to lines have to stretch.
I tried to add another transformation, like scale or distance, but that didn't stretch properly

Would you know an elegant way how to do that?

Thanks a lot for help and sorry to strain your patience, but maybe this help others too

Sketch a your side profile on the front face and extrude with parts in position.

You can also use the transform rotate the part.

Hope that helps.
