Sagebrush posted:A spline is a parametric curve -- a vector line defined by a mathematical function and a series of constants. It's how smooth curves are represented in CAD programs. There are different kinds of math that can be used to define a spline, but the most common is NURBS, the non-uniform rational b-spline technique. cool thanks

Anything that isn't parametric mechanical 3D CAD is literally MSpaint garbage for children.

when i designed packaging we used some cad program called artioscad. it would probably suck for anything outside of that specific application but it was pretty good at getting you up and going with drawing something up. the program that they were transitioning from, impact, would blue screenf and then to get it working again you'd have to unplug and plug the dongle back in.

When I worked doing CNC Routing the main software we used was CASMate and I would love to know if anyone here has ever heard of it. It was old, and required a parallel port dongle lol for licensing so it only ran on non NT windows (we used windows ME and when it crashed you had to reset) it was sign software. so in that regard it was a lot like illustrator, a lot of focus on the aesthetic of what you were doing, lots of tools for curves and text etc. BUT it had plenty of built in tools that allowed me to translate points with coords etc, and had a solid system of guides that allowed me to use specific coords too As far as 2D went I was shoehorning some reasonale CAD style stuff into that software. I was using waaaay beyond the scope of what it was designed to do, BUT it did it. And I feel ya re: Illustrator. why is it that such professional software is so poo poo

because it's always a small enough market that there's no real competition and/or no market pressure to improve, and because people use it for a job instead of for fun so they're willing to put up with garbage interfaces and train themselves around the software's problems

Lomarf Blender as CAD holy gently caress. I mean even using Blender Mechanical, things like "drafting" and "assembly constraints" are still on the Devs wish list which makes it worthless for like 99.9% of professional applications. It's probably just as usable for idiot spare time projects as any other free CAD software, but I doubt Boeing or Volkswagen are gonna fall over themselves to switch anytime soon.

if you like poo poo engineering software you should join us on the cam side. i love having to redo all the engineer's work in mastercam because it imported their solids as polygonal surfaces because this $14000 a year piece of poo poo can't properly import the most common cad format out there and that chunk of steel came out of the machine all faceted. dear engineers, when I machine your part you're really just getting an approximation because i have to use surface smoothing kinda sorta close to tolerance to turn that polygonal mess of poo poo into smooth surfaces the industry is also in a transitional period where all the graybeards are retiring or dying but there's still enough of them around with enough clout to stop you from being able to do stuff the better modern way. i love taking four hours to do a job that could be done in 20 minutes because you never heard of dynamic toolpaths even though trochoidal milling has been a thing for at least a decade. i know it looks scary when the machine works like that, no stop crying its okay, the smoke is normal don't turn on the coolant you'll gently caress it all up Sauer fucked around with this message at 18:05 on Nov 19, 2017 |

i have a student who uses blender predominantly and while it's not at all suitable for mechanical cad, it seems to work well for his "work the shape out freeform and then recreate it accurately at a later date" workflow. certainly he is pretty fast with the interface, though he says he's been using it "since high school" so 4-8 years i recommended rhino + t-splines to him though because it's a similar technique but builds nurbs instead of sub-d poly surfaces.

oh and lol @ "superior for an efficient workflow". any proper cad program will have its interface almost completely customizable (and NOT by compiling from source) so that pros can set up the workflow that they need. maya started out as a plugin host and scripting interface bc the needs of, say, an animator are totally different from the needs of a texture artist or a modeler

no floating windows is a good concept as is right click to select. if you know the hot keys you can fly like a dragon and the different workspaces once you get used to it is super duper I used to HATE when id load up a blender file from someone else because it would change the UI layout, but now I know exactly why youd do that, and spending a couple minutes setting up workspaces at the start saves so much time and is so cool and good

you should pirate a copy of rhino and of t-splines and start screwing around with that. i think it would suit your art very well

rhino reads and writes every format ever invented there are also plugins for most modern renderers that let you run them directly from rhino

NX has middle-click to press the highlighted button and it's so good, it pisses me off every time I try and use it elsewhere and remember other software doesn't do that.
