Pipe with arc's

Kai_himself

Hello,

i like to draw a pipe with two 45° Arc's. First i build up the straight pipes, then i rotate the arc's, at least i like to unite all.

Sometimes it works flawless and sometimes only the "arc" will remain as a sphere ...

Why is it so complicated to unite the parts ?

Good morning Kai. I would suggest that you use the sweep tool for something like this. A lot less work to accomplish what you want. A path can be drawn in 3d space with not too much trouble.

Hey,

thank you very much, this way is much better. But how do you make these nice 45° Arc's ?

Is it a Spline ?

Best regards

Kai

Edit: I saw it, they were midle point arc's.

Again, thank you very much !

The great thing about a program like Onshape is, it gives you numerous options

Here is another way — by no means the best – but rather, just another option

A desktop user can do this more efficiently

This way takes 2 features

In the sketch I use the —

Line tool

Dimension tool

Tangent arc tool 

Tangent constraint

Then I use a custom featurescript called Pipe

The pipe tool is straightforward. Once you install it, you’ll see

Sorry for the jerky GIF. That’s the best I could do on a longer GIF on my iPhone
