Joining in 3D space

[blackmath]

Hi everyone,

I'm new to Fusion360 and running into some snags. I'm trying to create a unibody pipe of sorts in 3D space to model a sculpture. The joins at 3 points are not coming dogeter cleanly. Any help would be really appreciated.

I've uploaded my file here and pasted screenshots of the problem areas.

Hi,

Thanks for posting, and welcome to Fusion 360.

The reason your corners are mitered is you used "chain selection" for the first "z" shape. This will cause miters at those corners. The vertical pipes then dive into that already bad corner.

I'm not sure how you want the corners to look when done. This would probably depend a lot on your actual fabrication process.

How would you create the corners you want in the real world? That process can probably be done inside Fusion. Can you post a picture of an example?

In the meantime, here is a video showing a different workflow that produces fairly neat corners, but looking at it, I cannot imagine which pipe is used to create the actual elbow. Good luck!

Thanks,

Hi Phil,

This is very helpful but I'm getting stuck since I'm using hollow pipe. How do I patch hollow segments? What you've done is exactly what I want to do but I'm using hollow pipe. I'm basically trying to replicate the following pipe piece: http://www.essentialhardware.com/media/catalog/product/cache/2/image/380x/9df78eab33525d08d6e5fb8d27...

Here's an example rendering I was able to make - you can see the join in question is still not as clean as your screencast

In your rendering I can see you did not turn off Chain selection. The corners are still mitered.

This will force you to make a pipe for each section, but that is what you want for this workflow.

(turn off chain selection)

The other thing you can do is model it as non-hollow, then use Shell command after you have joined everything and made your one big body.

Thanks,
