Bigger after unrolling


(Edward) #1

strange numbers after unrolling, what does it mean?

(1.#J % ) bigger after unrolling

Command: _UnrollSrf
Select surface or polysurface to unroll ( Explode=Yes Labels=No KeepProperties=No RelativeTolerance=0.01 ):
Calculating starting area… Press Esc to cancel
Select curves on surface to unroll ( Explode=Yes Labels=No KeepProperties=No ):
Calculating starting area… Press Esc to cancel
Area is 2608463.0182 sq millimeters (1.#J % ) bigger after unrolling
Two surfaces unrolled.
Creating meshes… Press Esc to cancel

Thanks edward

Can you upload a .3dm file with the surface?

What was the surface area before unrolling (Area command)?

unroll.3dm (44.2 KB)
now it is a trimed part of a surface made with devsrf
if I untrim it I don’t see the (1.#J % ) but Area difference is within tolerance

Area was almost the same.

Hi EOStam- I see this as well, thanks for the report. It looks like UnrollSrf is taking the starting area as 0 for some reason.
If you DupBorder, Untrim, then re-trim with the border curve, it behaves better.
