Hi Alex,

I doubt this has anything to do with Parasolid vs OpenNURBS. Both are capable of analytic representation of a torus.

I'm guessing that Pipebend is smart enough to look at general surfaces and check whether they are sufficiently close to being a true torus. The key word here is "sufficiently" because if MoI and Pipebend use different tolerances for "close enough" then sometimes they are going to agree, and sometimes not.

One thing you could do is look through the Pipebend settings to see if there's an import tolerance setting somewhere. If there is, you could try setting it to a larger number like 0.03 mm.

Thanks again for input definitely shedding some light on the internal process of file translations.
I checked in Pipebend and yes there is a option for loosening the tolerance in the import I will have a play with that and see if that gets all the MOI files flowing in.

Just getting the next project ready to start bending 90m of 20mm pipe bent and welded into one continuous pencil style drawing.

Modelled in Moi should be completed in the next couple of months.

Neat design Alex, where will it be installed?

Thanks Larry - will be installed in September on Currumbin Beach - Gold Coast Australia.
Almost there working out the mechanics of bending this much tube ill post some production shots as it comes to life.
No rest for the wicked!
