Flat pattern in Fusion 360

Anonymous — Thu, 22 Mar 2018 14:24:48 GMT

Hey, I'm new to Fusion 360. I have created a sheet metal body without creating a new component in the beginning. Now it is not possible to create a flat pattern. Please someone give an idea to get a flat pattern from my sheet metal body.

Can you File>Export and then Attach the *.f3d file here?

Can you recreate the part from scratch?

Sir, its bit difficult to recreate the part due to time constrains I have. I'm attaching my design in .f3d file formate herewith. expecting your reply ASAP.

Here's one way to create the dxf:

Unfold the body.
Create a sketch using one of the faces of the unfolded body.
Project all of the other faces to the sketch.
Export as dxf.

If you need the center bend lines:

Create Flat Pattern (it will ask if you want to use the existing pattern. Answer yes.).
Import the dxf previously created.
Edit the sketch (select Edit Sketch from the sketch menu).
You may need to mirror the sketch geometry and move it to be in the same position as the flat pattern.
Project the bend lines.
Export the edited sketch as a dxf.

p.s. This sketch will only be visible while you're in the Flat Pattern mode.

First thing I notice is that your Profile and Path are in the same sketch - it would never have occurred to me to do this. Can you Project the profile to a new sketch and convert the original to Construction?

Second thing I notice is that your Profile is not on a plane Perpendicular to the start of the helical path. I often see this as a mistake resulting in long feature solve time and incorrect resulting cross-section.

Hint: I did find several obvious interferences of geometry - physically impossible.

Are you familiar with the Fillet tool?

Hmmm. I also found an improperly cut edge (not perpendicular to the flat).
