    having a hard time joining c channels

    im new so i dont know exactly what im doing wrong but for some reason i cant join two C Channel beams together one is going horizontal (in the north view) and the one im trying to join or cut is going up at an angle of about 60 degrees. I have tried clicking on all joins, cuts, etc and none are doing what i need

    thanks

    Hi nickda40,

    When the two beams intersect, they are "joined" structurally. I assume what you are referring to is the visual representation where there is a small gap and a square end shown between the two beams.

    If you wish to visually have the second beam cut to the line of the first, extend the secon beam beyond the first. Create a reference plane and cut the second beam to the reference plane.

      And if you want to cut them both at an angle, exend both, draw a reference plane at the desired angle and use Cut Geometry for them both.

        First off, I don't like using what both Ian and Martijn are suggesting, but it will work if the following doesn't. If you want to miter them, just use the "beam/column joins" tool in the modify tab and have the arrows pointing away from each other ( <-- --> ). The beams have to be on the same elevation though, so that may be giving you an issue.

          uggghh this is so frustrating i cant figure out how to change the reference plane at an angle. it seems to only want to be flat on 1st floor or second plan view. I tried the beam/column joins and put them on the same elevation and nothing seemed to happen.

            nickda40,

            Might be handy if you posted a couple of screen shots of what you are wanting to do.

              you could try making some dummy geometry with a face at the desired angle, set your working plane on that. but yeah as Ian said, might get a better idea of what you want with some pictures

ID:	375248 hell im not even sure if im posting this pic correctly. But if you can see it, the black circle is where ive gotten close to connecting them just by playing the the extensions. But i was hoping i could cut off the excess showing and have them join at an angle where the meet.

                The one circled in blue are two L angles with thin plates that i just placed as if they were "welded" together. However i tried highlighting all the members at once and wanted to have the cross sections slanted at 30 degrees the L angles change but its nearly impossible to get those plates anywhere close to looking like they are connected.

                  wait guys i got the reference plane figured out and to cut them!

                    For the connection of the cranked beam. In an elevation or section create a reference plane to cut the beams. drag the end of each beam beyond the refernce plane and cut them to the reference plane See attached jpg

                    The second part a bit further back is a bit hard to see, but the same process would work there as well.
