You did get some excellent sounding advice from several different directions ... so throw us a bone ... which one was the correct advice . Some/none/all/etc ? And beyond that , if you have some .STL knowledge to share with us , how about just placing that knowledge on the Wiki , where yourself and all others can add to it as that knowledge evolves with time . Seriously . I am not asking rhetorically , but am asking you directly "why not create a page on the Wiki?" . You give quick thanks , but perhaps that quick thanks could be transformed into a more substantial and significant effort ? People seem to have no problems with spewing information into an email ... so what is it about putting that effort into a more concentrated , more concise , more efficient means of sharing such info (the Wiki) that is turning everyone off ? I get private emails telling me to "back off" because everyone is simply too busy to contribute . I have another word for it ... SELFISHNESS ! A person may seem to be too busy to share , but not too busy to ask others to drop what they're doing and contribute to that person's particular , immediate momentary and monumental needs . Really , I am trying to get a grasp on this concept of "take, but only give back a little or , if lucky , none at all " . There is Vesa and there is Juha ... and there is all of us . studio www.niagara.com/~studio www.studiodynamics.net ----- Original Message ----- From: Charles R.

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.
