Technic connector and beam consultations
For a while now I've been working with different CAD systems and pretty much from the very beginning wondered if one would be able to build MOCs with it...
About this creation
Yes i know.

There is Lego Digital Designer, LDraw, MLCad and so on, and so forth... But each of those offer different possibilities in exchange for a lack of others. Seeing that I've decided to use professional CAD software to create flawless brick models which after that one could connect to each other with ease in the same program and lastly apply at least basic visual effects to make it look more realistic. All functions within one software.

___________________________________________________

After some testing made within most popular CADs for which I have licenses due to my work and education (mechanical engineering) I've chosen to use Autodesk (R) Inventor (TM).

Below and at the top you can find two models made by me today, which I post to consult with others. I personally think they're OK, but I'd like to hear your opinions. Please comment, criticize and leave ratings, since I'd like to correct any mistakes before modeling more bricks.

The main picture and the next one is as you can see a basic Technic connector with friction. Do notice that the model doesn't include the surface roughness.



The next two pictures show a model of a T-shaped Technic beam.



The beam color is an actual LEGO light stone grey.



All models made with 0,1 mm precision.

ATTENTION: At the moment I'm not posting the dimensions since I'm not sure if it is legal. I've send an e-mail to LEGO regarding this matter and I'm currently waiting for an answer.

You did a great job. I worked with inventer also, but never draw lego. I thougt about it but to make an assambly you'll need a big computey to get the graffics going.

Quoting Sebeus I It would be illegal if you would use these to produce real parts and sell them. posting dimension of parts is perfectly fine, after all, with some decent equipment one could easely measure the parts. For fun I designed a lego part in SolidWorks a while ago :P
Yeah thought so, but never the less a confirmation will be nice :) By the way I've worked with Solid during my studies and was seriously concidering using it for this project.
Quoting Paul Beach I think you're onto something! :)
Nice to hear that! :D
Quoting Kayla Rhodes Cool! I take engineering at my high school and we use Autodesk Inventor too! The first year I took that class, two years ago we had to reverse engineer a toy of our choice and make its parts in Inventor. I chose to do the Hoth Battle pack (the one with the Snowtroopers). I built the part with the gun. It had about 21-22 LEGO pieces. It was a lot of work dimensioning all of the pieces because you had to build them from scratch but it was a lot of fun though.
Exactly :) I've started off with the most simple parts. It's easy to make the basic elements such as beams, axles, connectors etc., because if you measure one type of beam it's pretty much like you'd measured them all. The difficult part is way ahead of me :) So far a digital caliper was enough :P
