I have a need for 2 aluminum plates with 6mm and 10mm milling and tapping. Some notes:
The drawings show these plates as 10mm thick but 1/4" can be used if you can tap 6mm in the side of it. I have attached Rhino 3dm but I can provide other formats. You provide the material since I want it yesterday. Tolerances are to within .005" even though the drawing is in metric units.

can you post in dwg ?

I don't usually have much luck with autocad but here it is:

Release 2000 (have others)
curves as polylines
surfaces as polygon meshes

I think these are much better.

Curves as splines
Surfaces as curves
w/ 3d faces

My cad hates Autocad 2000 dwgs :(

You may want to go to .5 plate if possible, 1/4" = .25, 6mm=.236 so that wont float, 3/8" is really on the skinny side as well.It would make life simpler to convert to imperial.

Edit:
Where you located?


Ken

Here they are in Release 12. I have others.

You did not respond to the conversion to imperial suggestion, for .5 plate or where you are from, if you get together with someone this will be important.

I am from Clermont, Florida 34711. The drawing may be changed to imperial and you may use .5" plate. The slots and other features must still adhere to the .005" tolerance from the drawing, including the error for the imperial conversion.
