Unable to create Flat pattern

[hansjb]

Hello All,

I'm unable to create a flat pattern, Any suggestions would be appreciated.

Thank you,

Put dimensions and constraints in the sketch and use same thickness in the whole sketch.

Also be sure to enter sheet metal rules for the thickness of your sheet.

Good luck

Problem 1

As indicated - Your sketch is not constrained - read this

Problem 2

Your part is not uniform thickness, but sheet metal requirement is uniform thickness.

Problem 3 you used Extrude rather than sheet metal tools?

Problem 4 - you are doing too much work, get lazy.

Edit Sketch1 and notice only one side open profile needed.
