Flatten curves parts for laser cutting

graham_lockgraham_lock Member Posts: 157 PRO
Hi,

I'm new to Onshape and I'm trying to understand how to flatten curved parts for laser cutting.

Essentially I want to use Onshape to design RC planes, the parts will be laser cut from balsa and ply woods.

Many of the balsa skins will be curved in the 3D model - turtle decks, curved fuselage sides, etc, so I will need to flatten them for cutting.

In the screenshot below you can see I started with a sketched arc, extruded it to get Part 1, converted to sheet metal and then opened the sheet metal table.

Converting the arc produced an additional 5 parts which also appear in the sheet metal table.

All I need is a flattened version of the extrude?

Any help appreciated.

Thanks.

    "convert" creates parts for all the faces of you body. Either use the "faces to exclude" or use the "thicken" option in the sheet metal feature instead of "convert".
