[Beginner] Modeling – Connecting / Joining

[Brian Jones]

a couple ways, the easiest is assuming you are sweeping that profile along a spline, just sweep along one spline to make both sides and the corner is automatic.
If those are two pieces of geometry now, lengthen them so they intersect each other and use Boole to cut the shape of each into the other, then trim the extra bits. I can do some quick images if you need to do that.

Thank you very much for you response and help, I will try out the options that you suggested and see how it works out,
but for now I did a 45° cut with “Knife Tool”, adjusted the position and then used “Weld” to stitch them together and it
worked pretty good, but I guess it’s not the most efficient way in terms of speed.

the knife at 45° is also a good way. The boole way is nice since everything is aligned already but it’s not fast either. The quickest way is to Sweep the profile spline, which makes the shape, along a ‘base’ spline which has the corners in it already.
