Creating a tube with rounded corners?
Creating a tube with rounded corners?
(OP)
Hello,
In the attached image is 3 different ways to create a tube. What I want is to create the C version but without having to add a sketch fillet. The reason I don't want to add a sketch fillet is because there is a situation where I have a collection of straight lines in 3D space, and I want to save the time of adding Circular Blend Curves to all corners, and also because I want to be able to adjust the diameter of the tube and have the size of the corners radiuses updated automatically. So, is there a way to create a sketch like in the A version and have a tube created that automatically adds a radius to the resulting tube corner?

Create an expression that will drive both the tube diameter and the blend curves.

Attached is an image showing a Tube on a path consisting of several straight lines, with Circular Blend Curves added as corners. The blend curves radius are controlled by the formula TubeDia/2, and the tube outer diameter controlled by the formula TubeDia with a value of 30. This method works fine.
Tomas, I'm not familiar with Routing, is that easier than this way?

if you don't it's a quite different application with it's own working methods , and ... a learning curve...
Another "problem" with routing is that one needs to do quite a lot of system setup before one can use it efficiently.

A tube is bent around a radial form, sometimes using an internal mandrel to avoid collapsing the tube. It needs to be swept along a guide that includes a bending radius between your straight sections.
You want other people to use your model afterwards, don't you?

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?

Maybe a "bend radius" parameter could be added to the tube feature in future, to work just like contour flange.
You never know.
