![]() I simply approach it as a way to move shapes around and add things and take them away. You don't actually need to be able to work out exactly where anything goes first time - you can simply change numbers till it fits the way you want it to. You just need to remember what brackets go where. Simply because: you don't need to know why the brackets are where they are. I don't believe you need to be a programmer, or know any programming practices or conventions to use openscad. I have a different approach to pretty much everyone else here :-)īeyond basic arithmetic - I never bothered to pay attention during math classes, assuming (correctly lol) that I'd never need any of it in the future. Try it out and get a feel for this too, If you want a simple translation of the object and then it rotated on the spot, do the translation first. For example, if you rotate first, then translate, the object will move about as you vary the rotation because "the translation gets rotated with the object" - because it is after the rotation in the source. With cylinders, you'll need one of these to turn it on its side and may need another to orientate it in space.Īnother trick is to remember the translation or rotation you do first will affect all transformations following it. I start with rotate(90,) and then vary the axis until I get the right result. You should soon grasp it.Īfter that, rotations are the biggest hurdle. Then change the numbers and get a grasp of the effect of each number. Just copy the source code of one of the examples, paste it into a. It currently redirects to a browser window here Run OpenSCAD, Top menu, Help, Cheat Sheet :-) Sometimes it really is that simple - he he So, where does one find the OpenSCAD tutorial that would let in enough light to help me see where I'm going Where is the Cheatsheet for the official OpenSCAD Cheatsheet? I completely agree that the programmers should never be allowed to write the manual (which was iterated in a few threads I read). I have looked at the Cheatsheet countless times. Sure, I can draw a cube, but I don't know enough terminology to be able to search the Manual for help filling in the blanks the manual is hopping over. First Steps' was useful, but it didn't flow in a logical progression for learning. It is just obvious that I must know how to use OpenSCAD if I am serious about executing my own 3D Designs for our 3D Printer (since I will never be able to afford my own copy of AutoCAD). I looked through the entire list of Topics for this group and read through all that seemed geared to a person trying to learn OpenSCAD on their own. I can now make a cube (or cuboid) reliably. I started (like Dad used to) with the OpenSCAD User Manual. I can look at a program in Basic & see where it's going, but I failed 'Basic 101' absolutely. I understand the way the grammar of programming languages works & know that if I fail to understand this, I will not succeed in learning OpenSCAD. I taught myself architectural design principles, designed the house we live in, did our blueprints in DataCAD 11LT (also self-taught), was the defacto site supervisor during construction, & managed to break only one finger with my hammer over the entire build. I took 'Drafting 101' 30 years ago when CAD was an optional class you could only take AFTER learning to draft with triangles & a T-square on actual paper. ![]() I'm reasonably intelligent & good at Math (Intro to Trig has annoyingly fled my memory but I'm great at Geometry). I'm not in a hurry and I don't have a deadline. I'm ready and DETERMINED to learn OpenSCAD & am certain I have the mental wherewithal to accomplish this.
