Pipe

[tmccar]

I am modelling a section of pipe with bends in 2 planes. The way I am doing it is to draw the centreline (using 2 sketch planes) and sweep a circular profile along it.
When I select "sweep" and click on the profile, it only highlights part of the profile (that was created in one of the sketch planes). How can I get it to select the whole thing?

[Josh_Petitt]

did you draw the profile and path as seperate sketches? you should be able to select the profile, then the path and it will sweep.

Zip and attach the file.

Did you Project Geometry to get the endpoint of one sketch to use to continue the next sketch?

Is the behavior you are seeing anything like this?

My mistake - I was selecting the profile as the path.
I now want to take one end of my pipe and "twist" it through 180 degrees. Can I split the sweep into sections, or edit the section in situ?

Have you read this document?

You didn't state what release you are using, this paper might be more appropriate -

I noticed your Sketch1 isn't constrained making use of symmetry about the origin and the browser history tree is way way way too complicated for this simple geometry. Message was edited by: JD Mather

Here is my browser history for the same geometry.

Here are the 3 sketches needed.

Sketch1 with 45° construction line.

Forgot the attachment.

Workplane 1 using 45° sketch line and perpendicular origin plane.

can you post your files? 😉 (sorry couldn't resist)

[JDMather]

Sketch2 on 45° workplane.

I think you can figure out Sketch3 (the circle profile).

Hi JD
Thanks for your help. Could you save this as an Inventor 11 file?

No, I don't have Inventor 11. I posted step-by-step images to get it done in v11.
