Extremely difficult to create Flat Blank surface from lines

Recommended Posts

Hi everyone,
Normally, when we running the forming analysis for some part, we will run feasibility first and try-out then.
OneStep analysis provides a flatten Blank, but only in bounding lines, not surfaces.

Then we need to use InspireForm to create the blank surface wireframe.
However, it is Extremely Difficult to do this.
IF always requires us to build another sketch, not directly fill in the lines to create the surfaces.
But the sketch sometime doesn't capture the points well.

We also cannot use "patch" tool in this case, because patch tool doesn't work with free lines.

Meanwhile, HyperMesh can do this very well.

So can anyone teach me how to create the surface efficiently with InspireForm?
I'm struggling with it.

Attached is the cad file of blank wireframe.
Thanks in advance!
