# Re: 3d sweep path using specific f(x,y,z) function

I've attached a part file that depicts the envelop divided into eight gores.

I'm not sure exactly what you are trying to acheive.  You have successfully modeled the shape of the gore, and it's easy enough to extract one of them from the envelope model you posted.

Inventor won't automatically create a flat pattern of this shape, if that's what you are looking for.

Do you already know the (x,y) function of the flat shape?  I guess I should look at the excel file you posted to see what you have already done.

I suppose a summary is in order:

• I have already calculated x,y-function of the flattened gore shape, and I have it's coordinates in the Excel file that I previously shared.
• I can input the coordinates from Excel into Inventor, but not associatively.
• I tried using the Point Linker plugin to make the link associative, but I get an error that prevents Point Linker from inputting any data. I copied this error into a previous post.
• I shared the .ipt file for the envelope divided into gores so that readers could better understand my posts.

More succinctly, Point Linker does not work and I need help to make it work, please.

Hi,

can you let me have your direct contact details (email them to gary.wassell@autodesk.com)?

We can then work with you directly to resolve the issue with PointLinker.

Thanks

Gary

With the help of a/the Point Linker developer, I now have a working add-on. I suppose the community will see an update to Point Linker, but I will leave such a speculation for the developer(s) to confirm, deny, or neither. Many thanks!

Is there reason you didn't use the Origin and didn't use the existing Origin workplane and axis and instead re-created these?

Is there a reason your first sketch is missing horizontal constraint on the line and not fully constrained?

Hi,

yes we'll post an update to the PointLinker app on Autodesk Labs in due course.

Cheers

I don't remember exactly why, but I probably started the sketch at the origin and then decided to try sketching differenly right below where I started. I think I originally tried to define the outline of the envelope parametrically with a spline, starting at the origin, but it got ugly, so I erased it.

To answer your second question, no, but I hope the part file helped to illustrate my posts as I intended.
