Anyone using fit spline in a weldment sketch?

Hello All,

I am running SW 2010 sp3.1 on a 64bit windows 7 system today. I am trying to make a weldment of a steel cage for some subsea equipment that requires some 1" round bar be bend at 60 deg to taper into another section of the cage. Admittedly I don't work with weldments everyday but I used to do this in the past for sure in 2009 and earlier versions

1. Draw two lines with an angle of 60 degrees

2. Add a sketch fillet of any value between the lines

3. Then select all three segments and create a fit spline

4. Use the fit spline as a path for the weldment structural member.

When I try this in 2010 it won't even select the fit spline. If I remove the fit spline I then need to select all three segments individually and it gives me three seperate solid bodies; obviously not what I need.

Has anyone else run into this?

No one else has this question

It turns out you cannot use a fit spline or any spline for that matter in a weldment structural member path.....did I mention I don't use weldments much? ;-)

I found this in the KB, I must have been using a sweep back then and didn't remember correctly. I did submit an ER though under WELDMENTS>STRUCTURAL MEMBERS and used works like "fit spline" and "weldment" in my description in case anyone else would find this useful.

Can a helix or spline be used for weldment paths?

No, weldment parts cannot be created from splines or helical paths. Users can use a sweep feature to sweep the weldment profile along a helical or spline path, however SolidWorks will not be able to generate a cut-list item.No, weldment parts cannot be created from splines or helical paths.

Why would you need to fit a spline? When you insert a structural member on a series of line segments and arcs that are tangent to each other, as in your case, there is a checkbox in the structural member dialog that lets you choose to merge the bodies, such that all along the (tangent) segments you get one single cutlist item.
