Sheet Metal Model - Curved Surface

Member Posts: 10 ✭
I started making a geometrically abstracted fire hydrant out of surfaces. I simplified the form with the intent of creating a sheet metal model and a flat pattern. BUUT The curved surfaces do not want to participate in the sheet metal model. (The green surfaces are all independent of the larger sections of the model - thought that might be a work around, by reducing complexity?)
I have done some searching in the forum, but can't seem to find an answer that will help me make progress with this project as it is currently modeled. I know there are limitation to the sheet metal model script, but I thought it would be able to flatten a constant curve between two parallel edges.
Here is a link to the file if you are interested in taking a look: https://cad.onshape.com/documents/fe2ca22f53687f237d78762c/w/cc6d3c2197a9f1d55267118e/e/c9fcc255fdc6940c44d0a322?renderMode=0&uiState=62f46e0b80019c326a116f72

You modeled the curved sections with a loft, which is not something that can be "unfolded".
You should be able to create something very similar using a "revolve" instead (and a trimming the sides from a top view so it tapers). That should be able to unfold.0 -

Here's what I was talking about earlier if you still want a smooth curve in one direction, each "face" of the model is in one piece:

Hi @bryan_lagrange . I want to create something very similar to the test dome. How did you build it? I am familiar with sheet metal tools but not working with curved surfaces. I want to be able to flatten out curved shapes to cut on lasers and plasma cutters. Thanks
