Hello All, I am new to the group.

I need to design a dome in solidworks, could you give some hints?

I expect the dome to have the following properties

Dome shape: Hemi-sphere; 
Dome radius: ~570mm 

Dome element: hexagons
hexagon diameter: ~80mm 

Thanks!!!
PS: for refernece, see attached image

Solidworks says it will import VRML. If it will import the
VRML output from Antiprism (http://www.antiprism.com) then
you can import any of the Antiprism geodesic models.

http://www.antiprism.com/examples/150_named_models/580_geodesic_duals/

I have attached an example VRML file similar to what you posted
so you can check if the import works. The Antiprism command to
make it was

off2vrml -t no_tri std_geo_10_0_d > std_geo_10_0_d.wrl

If Solidworks prints any error messages for the import, whether
or not it succeeds, I would be interested if you could post them.

That model included vertex spheres and edge cylinders, which
probably aren't of interest. I have included the model again with
just the face data, from the command

off2vrml -t no_tri -x ve std_geo_10_0_d > std_geo_10_0_dB.wrl

Helo Adrian. Interesting solution and thank you for your help. Will try importing the files from antiprism and let you know.

Another question on antiprism (btw nice project): is it possible to make the hexagons all the same? Do the colors in the graphs represent different hexagon sizes?

Thanks again

Hello Adrian,

I got the following error message when trying to import the files (see attached): "failed to process file, may be empty file or contain unsupported geometry types, etc"

This happens with both files.

Thanks

Julian,

Inline image 1

Here are several 3D file formats, with which to experiment. (I have best luck with AutoCAD DXF format):

-Taff
Goldberg {10,0}.dxf
Goldberg_10_0.wrl
Goldberg_10_0.3ds
Goldberg {10,0}.skp

Julian,
Sometimes I use SolidWorks eDrawings 2013 (version 13.2.0.110) to display 3D models. It will import AutoCAD files in .dxf format, like the one Taff posted, but not VRML files (.wrl).

The polygons are coloured according to symmetry. If you, rotate
or mirror the geodesic sphere so it coincides with its original
position, then each polygon is carried onto another. The polygons
in each set where any one can be carried onto another are coloured
with the same colour.

It is not possible for the hexagons to be all the same shape
while preserving the symmetry of the model.

Thanks for the error message from Solidworks. I had a report
last week that Blender would import the output from off2vrml,
so I was interested in whether Solidworks would also be able
to import it.

Adrian.

hello group! I want to build a sphere, can someone help me with the design?
