CAD or Other Files Containing Dimension Specifications

Hi all,

Are there AutoCAD or AutoCAD-like compliant files containing the dimensions for the extruder pump? I want to machine my own but I havent' been able to find files I can get dimensions off of. Any help would be appreciated.

Nop has machined a set of parts for the Mk II. Maybe you should see what he has.

Demented,
I manually extracted dimensions from AOI and made 2D drawings in Visio with dimension lines on them. I then manually used those dimensions to make Python scripts to mill the parts. Let me know if they are of any use to you and I will post them up on my blog.

Nophead,

Yeah, those would be very useful. I think one of the big hurdles to getting a RepStrap going is a lack of support for filetypes and standards people are used to dealing with. If you would post those files, I would be very greatful.

Demented,
I have put the drawings up on my blog at [hydraraptor.blogspot.com] but having reviewed them I did change a few things and some things are out of date so beware. I have attached the Visio source file.

Nophead,

Thanks for posting those drawings. They are exactly what I needed. I haven't got my AOI up and running correctly so I was having trouble dimensioning these parts. Everytime I open an STL file in AOI it tells me it isn't a Gzip format and won't open it. I don't know what is going on and haven't really taken much time to fix it as I'm more interested in my physical build at this point.

Thanks for the files.

The AOI trick is to import the stl, not open it.
You also have to have the STL plugin installed it is referenced in the how to build reprap stuff.

The way to get dimensions is to draw a curve (in this case a straight line) across the dimensions you want to measure and then read the length of the line from its window on the right.

Dan,

Thanks, I suppose I didn't read the installation documentation very well. I'll get that done and see where I'm at then. I really do need to get my software up and running as I'm getting very close to having a complete system here.

Would you by any chance happen to have some CAD files (ProEngineer/AutoCAD/3DSMax) for Reprap? I am thinking of designing the machine virtually too and a headstart would be nice, although I do not know animations yet.
