CAD systems capable of generating a mechanism from given points of support and trajectory?

Question

CAD/CAM

Are there CAD systems for which it would be possible to set the initial parameters in the form of axes of rotation, fulcrum, trajectories of movement and get an automatically generated model of the mechanism.
For example, I want to design some primitive mechanism for further printing on a 3d printer, but there is not enough knowledge of mechanics and experience. It would be great to be able to get an approximately suitable mechanical model in a couple of dozen clicks, or choose from the mass of proposed options.

Answer 1

All modern CAD systems have a built-in programming language. For AutoCAD and nanoCAD, for example, this language is AutoLISP .
On it, you can write a program that can draw anything complex.
As I understand it, you want to create a parametric 3D model that depends on input parameters.
I think it can be done. He himself once wrote small programs at the university. For example, enter input values ​​from the keyboard, specify the base points for building the part with the mouse (or hard-code them), display a table with the results, etc. I only did it in 2D, but AutoLISP works in 3D too, it just adds a third coordinate during calculations.
In this way, you can get a mechanism model that changes depending on the input parameters.
But I have never worked with 3D printers and I don’t know what file format they need to feed ...
There is another, more advanced option - Autodesk Inventor, a very powerful software product, which does not prevent you from mastering it at a basic level in one evening. In it, you can already visually create three-dimensional parts that can be made parametric. That is, you change the values ​​of some parameters, while other parameters are already changing themselves, according to your formulas. Here is an example video, though the quality is not very good, but everything is clear. Moreover, in this way it is possible to create a large number of "performations of the part", i.e. the same detail, but with different geometric dimensions (in the video from 8:26). You can quickly switch between them and export to other formats.
