Face splitting on piping

I want to create some small piping (i.e. a handrail)



However this happens.



Do you think its because i have other vertical pipes intersecting the main horizontal pipe.

All i know is that the method i have used has caused my compile times to shoot through the roof.

you have to much pitch, try either, decreasing the angles and adding segments, or use the arch tool.

currently, you are making the entire turn in only two steps, make it in 4 or even 8.

you may also need to use the vertex tool.

[edit] also, change the receiving angle of the hand bar itself.. currently its flat, and the entire curve is contained within the arch. clip the edge of the handrail to take a portion of the curve within itself.

Well i have made the whole thing func_wall. It cleared up two ends, i'm going to redo the other two to see if this helps.

The main problem is that the rail is very small so doing it in 8 sections is very difficult.

Really, anything this size should be modeled elsewhere and imported
into Hammer. While you can do it with brushes, it's painstaking and
doesn't usually look as good as a model.

Lucky for you, Valve already has lots of handrail models you could use.

alt+P and check for problems!

Also, use func_brush instead of func_wall.

It's the HL2 thing.

I believe the problem is off-grid vertecies. The ends are getting messed up because the floating point vertecies are rounded off. Just use a square brush, or a more simply rounded one for this purpose. Or even better, use a model. It will look better and take less of your system resources.
