Import of Polymesh solids from Rhino in Parasolid or STEP files

#1

Hi,

Im trying to import a solid into Shapr3d in STEP or Parasolid formats. I can import the solid successfully however i cannot subtract from the solid or do any boolean operations in shapr3d.

The workflow is as follows:
Export from Delftship (Hull Modelling Software) in IGES
Import into Rhino, Join all surfaces to create a CLOSED Parasolid. No naked edges.
Export from Rhino in either STEP or Parasolid x_t
Airdrop to my IPad Pro 2018 and import into Shapr3d.

The solid shape appears, it allows replace face however any boolean operations fail e.g subtract. I can successfully complete a union with the solid however nothing subtracting for some reason.

I did the exact same process (from Delftship to Shapr3d) with a simpler shape such as an open cube and it worked fine.

Many thanks for your assistance.

Kind regards,

Nick Lyons

Hi Nick,

would you be able to send the files to support@shapr3d.com, we will take a look at it.

Thanks for your patience

I’ve done a bit more investigation on this. When extruding a new solid, the program won’t subtract from the imported object. If I create a solid in shapr3d separately, then move the solid over the imported object and use the tools→subtract the subtraction will complete.

It appears there is an issue with the automatic Boolean subtraction when extruding solids into imported objects.

Another issue I found is that it doesn’t appear the imported object functions as a solid correctly. I cannot fillet or chamfer any edges.

Hope this helps.
