I am trying to use an existing 2D CAD drawing imported into Blender to create a 3D model so that I can use swiftBlock to create the blockMeshDict for OpenFOAM. From tutorials I have seen that the general way of doing this is to create faces made up of 3-4 points (http://www.youtube.com/watch?v=uLmlrc3vb1s) and then extrude the component however in my case there are a lot of points and will take a long time to create the required number of faces. Could anyone please let me know if this is the method you also use for your 2D cases or is there a much faster way of doing this?
I asked about this on the Blender forum but I have noticed that the majority of the Blender users "sculpt" their models rather than create from 2D drawings therefore, I was not able to get much help. |

I have managed to create simpler geometries without arcs and it worked fine the problems occur when I try to create it with the arcs. My other idea was to make the arc a straight line in blender and then manually change it to an arc in the created blockMeshDict file, however this did not work either as I could not create the faces using only hexahedrals in blender.
I am really struggling, could someone please help me with this by showing or explaining to me what procedure I should use to create the geometry? If a simpler alternative to Blender/swiftBlock exists for this geometry which is compatable with the solidMechanics solvers in OpenFOAM please let me know.
