I use MoI to design parts for 3D printing - Everything from fixtures to electronic enclosures to CNC machine components. Clearance is a big consideration as nobody likes having to drill or file parts to make them fit.

For bolt holes and heat-set brass inserts I use the method described by Barry above - That is, an object library of pre-defined "hole cutters".

For parts that fit together (example: a stepper motor boss fitting into a bracket hole) I normally enlarge the part (the motor) slightly by resizing it, perform the Boolean diff operation, then re-size the part back to its nominal dimensions. It would be cool to have a short cut key you could press just prior to a Boolean diff that would enlarge the resulting opening by a predefined clearance distance.

Hi Ed, I am almost expert at revolving plug type fixings now :0)

I do like this mcad approach below, kinda what I explained before. ..
It's its from Ironcad, oops dont like its price...

it's like create part, save it in 'library' (or object layer¿), apply holes to selected surface / hole position(s)...

This is sort of tidy interface works but even a list of variables would be workable and cover basic hole types.



Well documented here:

Just ideas or doable?

Hi,

Something like that should be possible.

See attached. These are the controls from a add-on for creating bolts, nuts, etc.

Hi Fredrick,

Yes. That is a good place to start with Max's script. Add a counterbore detail and a standardized sizing for clearance.

And don't forget the Orient / Line - Line who has Uniform, Stretch, None deformation!

Hi Pilou,

Nice tool that orient but not had time to try it yet.
I think really prefer 'Michaels Revolution'...

Basically, from working out my 'approach' to 'spin' a counterbore
or countersunk hole to precise 2d dimensions as the starting point...
it all got a bit experimental. From just about 5 profiling shapes the
'spinning tools' was born and this 'design' was created.

On one of the profiles I could even create a rivet inside a cylinder....

PS. Does the custom ui work on trial version, I had a quick go yesterday but got stuck ?

Hi stefano,

re:
> PS. Does the custom ui work on trial version, I had a quick go yesterday but got stuck ?

Yes, it does. You would want to get CustomUI.1.03.win.mac.zip , from here:

Hi Michael, thanks for rapid reply, well spotted I downloaded wrong version...Stefano.
