Hi,
I'm building a library of deck gear with Rhino3d 4.0-SP8.
In my 3dm file, I have say a fender assembled from a fender-tube (white) and a ropeholder (black),
assigned some rendering materials (White plastic, Black plastic) on each part.
I created also a CG point of the fender;
Now 'd like to reuse this a multiple times in my sailboat design.
So the best way to do this with Rhino4-SP8 is to use the 'Block' functionality.
And why not to assign a Orca3D properties to it ?

I created a new Orca3D Material, let say 'Fender-B50', 6Kg, 100€.
Now assign this Orca3D Material to my fender object.
I tried several combinations, but without luck
Solution A)- Assemble the parts in a Block, use the CG point as 'ModelBasePoint'; name it. Name also the Rhino Object name.
- Assign to the myFender Object the Orca3D weight property Fender-B50'
- Orca3D see it as a Point, good !
- Show Orca3D.W/C Report : Weight result is 0.0 ! LCG,TCG,VCG are set to 0.0
Solution B)
- Assign to the CG point of the fender the Orca3D weight property Fender-B50'
- Orca3D see it as a Point, just plain normal.
- Assemble the parts (and GC point) in a Block, name it; name also the Rhino Object name.
- Show Orca3D.W/C Report : Weight result is 6.0 kg ! Marvelous !
- Helas, the CG info of this Orca3D item is incorrect : LCG=0.0 TCG = 0.0 VCG = 0.0

Solution C)
- Assign to the CG point of the fender the Orca3D weight property Fender-B50'
- Assemble the fender parts Tube & Rope (NOT the GC point) in a Block, name it; name also the Rhino Object name.
- Group this Bloc with the GC point.
- Show Orca3D.W/C Report : Weight result is 6.0 kg ; CG info of this Orca3D item IS correct.
- Helas,when you import this block in the main 3dm file. GC point is lost
This solution can NOT be used further FMPOV.
Is there another way to do it ?
Could Solution A) or B) be implemented in next release ?
Maybe it's a bug ?
Thanks to take this in consideration.
Keep on going !
