Create a surface between a curve and its offset

Hi guys,

I'm new and i have a problem to create a surface between a close curve and its offset. can anyone give the command to make that?
i tried to create two planar surface from my two curve and to make a subtraction between the two surface. but it's not working....

I tried to loft the two curve but it's not working...

and then i tried to write here.

If someone has the answer please help!

Thanks

Michi

You need to make sure that your two curves are on the same branch level.

Preferably the offset curve should reside on the {0} branch which means that when both are put into the loft component branch {0} (N = 2)

You can do this by either Flattening the Input to Loft or use the Shift Paths component like the image below.

I should mention the benefits of shifting the path is that it allows you to have multiple sources.

Where as Flatten isn't so friendly

I can't find the command with the leaf and the arrow.
what is exactly the name of it?

Thanks a lot

What version are you using?

Its called [Shift Paths]. Located on the Sets Tab>Tree Panel

Shift Paths was introduced latter that that. You will need to do this manually then.

Use a Path Mapper Component also found on the Sets Tab>Tree Panel and (using my example above) create a Mask to map the input from {A;B} --> {A}

The Mask is made up of a unique ID representing each level of the Branching structure for the input Path and then a target mask using the same IDs.

This case two levels of Branches A and B become one less level just A. If you had more then it could have looked like this {A;B;C;D;E;F} --> {A;B;C;D;E} again only one less level.

You can find out the Input Path Structure by hovering over the Output and seeing it in the popup or use a Param Viewer component found on the Params Tab>Special Panel.
