Hi,
is this bug back?
What can I do? change things what is causing the problem?
Rhino doesn’t tell the problem.
can’t upload drawing because it’s a complete boat and I can’t share it

Your curve might be open.
Is this in Rhino or Grasshopper?
it is in rhino 8
no, I only have surfaces (area)
Hi @E.O.Stam
Have you checked for bad surfaces?
If you still encounter “unable to calculate area” message after resolving or hiding bad surfaces I suggest you to:
-
Select all Surfaces, explode eventual polysurfaces to simple surfaces.
-
Select all Surfaces
-
Export selected as Object Properties *.CSV
-
Open Excel, go to Data \ Get & transform Data \ From Text/ CSV \ Load CSV
-
Filter by Area, unselect all, then choose “blanks”
-
If curves or other objects are in the file, filter and leave only surfaces on
-
You’ll see a list of object with no area, probably due to some inaccurate or self-overlapping trimming contours.
-
Browse to Object ID and copy it
-
Go back to Rhino, type _SelID, then paste the ID you just copied from Excel
-
Offending object will be selected
-
Isolate this object and try to fix it by rebuilding or just untrim and trim again.
-
Repeat this for all “no area” instances.
Unfortunately you have to repeat it for each ID, I dunno if there is some other way to script it or pinpoint NoArea surfaces without involving CSV…
This should resolve the NoArea issue.
I work with boats as well and I encounter this sometime when getting from outside dirty files.
Could be due to some translation error during import / export or different tolerance settings.
thank you Luca,
solved
I also have peters tools and did it with that plugin, 1 part was not oke.
so no bug in Rhino but a bad draftsman designer.
have a good day
Happy you solved it,
Peter’s Tools are great!

thanks!
