Equal pipe length
Equal pipe length
(OP)
Hello, people
How can I make equal length pipes? I tried equations but unsuccessfully.
I tried with splines, and smart dimension the splines, but then if you change the position of the point, don't know why the total measure is not the same.

It is attached the file.

Thanks alot for the info.
Here it is, I'm not sure if the splines have the same length, I used the smart dimension.
Sorry I do not know how you set the length with the global variable?
RE: Equal pipe length
Global Variable:
- Select tools, equations
- Under "Global Variables" click in the light grey cell "Add global variable", type a name for the global variable, I might suggest "runner length", then in the next cell to the right enter a value
- Now go into each sweep path sketch and edit the length dimension to equal the global variable you just created
Now all of your sweep paths will be constrained to the length set in the global variable regardless of how you stretch the spline around.I would also suggest you constrain the ends of the spline to be tangent to you first straight sections of each runner. On your current model the forward cyclinder is not going to flow very well with the sharp kink coming right out of the exhaust port, number 3 won't be happy either.

I did what you sugested with the splines, but I do not understand why sometimes the "tubes" seems to shrink, look at the 1 cylinder.
Is it possible to add points to the spline or I need to create a new one?
Thanks

I have seen that before and it was one of the setting either in the spline or the actual sweep feature variable, can't remember for sure, think it is the second, but let me see if I can figure it out and I will get back to you if you havn't found it yourself.
You can add aditonal control point to an exiting spline but I don't think that is you problem with the bulges.

FYI: your #1 cylinder is running right through #2 & 4 at the collector end, just in case you had not noticed

Thanks again!
