Re: Display problem of a model in flair and simplegeo

Thanks, Chris! That’s the problem.

Besides, I’ll talk about another related problem:

There are six bodies which make up of R1. In SimpleGeo, one can observe
some body by click on it in the CSG Tree window.

I select B1 and it appears on the right side and so are B3, B4 and B6.
However, when it comes to B2 and B5, nothing can be seen. What’s the
reason of this?

                          B1
B2

Cheers

Walker

Dear Walker,

I just had a quick look but I think the problem that you are facing is that
the intersection of B5 & B6 is nil and thus, neither SimpleGeo nor Flair
have anything to display for region 1. B6 is a cylinder parallel to the Y
axis with a Z coordinate of 514, whereas B5 is a plane with a normal
pointing (almost) in Z direction while it has a Z coordinate of -252.5.
Therefore, it won’t intersect your cylinder.

Cheers

Chris

**********************************************************************

When I import the input file into simplegeo or open it with flair and use
the ‘Geometry Editor’ function, the region R1 can’t be displayed.

R2 and R3 are normal.

The following picture is screenshot of R1 in CAD software.

Does anyone have any idea of what’s the problem?

Yours,

Walker
