Re: Grids and Metaball conversion...Thanks Stefan and Vesa

[Charles R. Henry]

Hi Stefan and Vesa, Thanks much for your help on this project that has been driving me batty for a long time. I finally got the result that I have been wanting which is to convert a sequence of 3682 spheres to an .STL file for 3D printing. Also thanks to Frank Dodd for BB and Michael Angel for  Export2STL.js .   If there is anyone that is working with .STL files, I'll be glad to tell you what I know.

Hello, Chuck   Thanks for your speedy reply.  I'm working on the grid first and finding that if I import a 1 inch cube from Rhino (which I know is calibrated to the 3D printer) into R3D and make the grid conform to it, then it requires the fields set to .0985, .0985, .0985 and there are 4 subdivisions per major division of the 1 inch cube.   But the measuring system reads .3938 as the length of the side of the cube. As Stefan said, just delete the old grids and create a new set of inch based grids.   There is a danger that when you import an object, some precision is lost or the import/export modules make wrong scale conversions.   The actual inch to meter conversion in Realsoft 3D is correct. Create an analytic cube which has 1 inch edges, change to meters and check the dimensions in the property window - the side is exactly 2.54 cm long.    Regarding metaball conversion: you can also multi select all spheres under teh metaball, delete them all and then convert the result toi SDS or triset. The sub spheres will be then excluded.   I hope this helps...     Best regards,   Vesa
