More engineering function?
Posted: Wed Oct 02, 2013 7:39 am
Is there any plans to give more, I guess you call it engineering functionality? Things such as defined grid, sub grid and snap grid sizes, definable chamfer and angle beveling? Tools for more control over dimensions/placement of objects.

Current plans are here: http://wiki.blender.org/index.php/Dev:Doc/Projects
Blender at it's heart is more of a mesh modeler than a CAD app. It lacks some fundamental CAD data structures like Dimensions and those implicit surfaces that are so nice for doing Boolean operations - all those CSG things than end up being a total pain when applied to Meshes.
Not to say it couldn't be done. But someone would have to pick up the ball and run with it.

Too me, that is all it is really missing. I tried rhino for awhile. Got in on it when it was still beta, but gave up at v3. Way too much money I don't have never will be any good with mesh, and is a royal pain to get nurbs stuff to shape the way you want or expect. I wish I had the money I wasted on it and the time wasted on it to lean Blender. I will say that Rhino had a really nice easy to use control system for moving zooming view and objects.

Blender is really not a CAD-application, and probably never will. If you wasted time on learning blender, you shoud have read about it before:
It's a DCC software, not to be used for engineering (it uses single precision for floating point operations all over).

I was talking about Rhino when I said wasted. Even with the limited cad side that Blender has, it works better. Just a lot harder to get some thing exact.

Do not mix what Rhino does with what Blender does! Rhino is a NURBS-modeler which is capable of producing mathematically correct surfaces for manufacturing (tooling, high grade milling etc, depends on your needs), even a car body which is just a redicously peckish business. Blender is an artistic tool first of all - if it looks good it is good. Doing a model for a 3D print does not require engineering tools due to the poor tolerances of the manufacturing. If you really need to do work with engineering there's really no alternative to paying for software. If it cocts money to make it most likely requires money to model. Unless you are just doing drawings of crap to be welded or assembled, then you can do it by hand just as well. BUT the good news are that there are a few cheap and capable programs out there (Alibre for instance). To make Blender a serious contender in engineering (which I think would be a waste off effort although I'd like to see it) a new mode is needed with support for geometry tolerances (or a 2D-module), booleans etc but it would still not be sufficiently accurate for engineering work. A converting module between, for instance, NURBS and quad-modelling is expensive (MODO has it and it costs nearly as much as MODO itself). Do the visualization and prototyping models in Blender but when it comes to engineering it's just not the right tool.
