Pipe Tool Segments

[Anonymous]

I'm wondering if there's a way to make the pipe tool not have segments on it. At the minute the pipe tool creates a segment for each line that's drawn in the sketch but unfortunately that's not compatible with the pipe bending software we've got and is actually undesirable anyway.

I tried to look into joining the paths together in the sketch but you can't do that in fusion unfortunately and you can't join the bodies together without segments appearing still.

The closest I managed to get to where I wanted to be was using create form then creating a pipe, once you've finished and move out of form you get a pipe with no joins despite any number of paths being drawn however the issue is I can't control the wall thickness etc

Thanks in advance for any advice!

I might be wrong, but based on your description  it seems you are  using the T-Spline environment to create these pipes ? Why ?

I'm not sure what you mean by T-Spline environment sorry. If I create a U shape path in 'model' mode using 2 lines and an arc then use the pipe tool it creates a pipe with 3 segments under one body it's really strange I just want to create a single, solid pipe.

At this point I am not sure I am interested in helping 😕

Are the arcs tangent to the lines ?

I just tried this and it creates a single solid body.

Sorry, I assume you mean the 'create form' or 'sculpt' mode but I didn't want to assume? I've not heard it called T-Spline personally. I've attached screenshots that show the difference in the two modes and it is about as far as I've managed to get. I suspect there's no other way in fusion and that ultimately I need to 'join paths' to prevent this being a problem but that's unfortunately not an option yet.

I tried tangent but it still ends up producing the 3 sections, I assume it does for you or am I being daft (entirely possible)?

There are no 3 segments. Both objects result in a single solid body.

If not, please export your design as a .f3d file and attach it to your next post.

File attached 🙂 thanks for your help so far

There is only one solid body in this design!

Maybe before picking up a complex software start with going through some of the online tutorials in the support and learning section of this forum. The Fusion 360 Fundamentals are a good start.

I've been using fusion for a while and made plenty of complicated designs but thanks for the advice...

You can see the 3 segments I'm complaining about clearly in your screenshot. Fusion 360 says it is 1 body but there is 3 segments which you can select individually and ultimately when you export said model as a step file it is actually treated as 3 individual parts that have a break in them, the pipe bending software we use won't accept a step file / pipe that's split into 3 pieces it needs it to be a single solid object that gets exported.

If you use the spline tool and create a similar path in one go with no breaks the pipe gets created and exported as I want it to. Or if you use sculpt mode you can get close but lose control over the pipe sizing, so I think in summary this seems to be impossible to achieve without having the join path feature.

Iv'e been using CAD, 3D modeling and computer graphics professionally for nearly  3 decades and have also created many complicated designs. I've been using Fusion 360 for 6 years.

The three "segments" are simply three analytical surfaces that make up this solid body. That isn't an inherent problem in any of the CAD software packages I've been working with.

When you use a spline it creates a single NURBS surface that also has "line" along its lengths indicating the sort/end of that NURBS patch. That same goes for for the T-Spline, which is in essence also converted to a NURBS surface.

Of the three CAD software packages I've used in the recent past (SolidWorks, Alibre Design and ZW3D) I believe they all handle that equivalency.

So at the moment the only thing I can say it is: It is what it is!

[Anonymous]

The difference in Solid Works I guess is that you can join paths which prevents this problem, ah well I guess as you say it is what it is I'll have to use something else for this specific design.

Entitled much @TrippyLighting?? No need to be a jerk. The guy is asking a legitimate question.
