I am sorry if I sound like a knuckle-head, 3d help

[EntDesLehew]

I am at my wits end. I can't seem to find out how to reshape 3d objects I create. Essentially I am trying to create a roof joist. I created the 2x6 member, pulled it to the length I wanted then rotated it into position. Now I just want to slice off the ends so I can have nice clean roof joists. I've used the SLICE command when I've worked with AutoCAD and I've had some success modeling in that program. I really want to do this kind of work in Vectorworks too. I'm completely self taught so I more than likely have numerous bad habits. I was considering purchasing the training guide but I wanted to make sure I was not wasting my money.

I feel the need to be able to move more into this world of 3d modeling on the computer with my work as a designer.

Any advice would be greatly appreciated as I have been kind of faking it for a while now.

There are several ways you can do this. The two easiest are Split using the split by line option or create a cutting object and to a subtract solids.

You will need to rotate the view so you can get a proper view of the joist so you can see where you want to cut it.
