Hi,

I usually do all my design work freehand in pencil, so I thought it was high time I kicked it up a bit and learned some CAD. I've been trying the open source FreeCAD program. It seems powerful, if a bit buggy and incomplete. I'm finding the learning curve pretty steep, so I was wondering if there were any users here that could share ideas and techniques.

Problems aside, I'm finding the process of building models in software really helps to clarify my ideas about what I'm trying to build. And a set of models on the computer ought to provide a better history if I need to build something again than the current stack of oily paper that's threatening to swallow up my workbench!!

Here's the beginnings of a model that I started this morning for the slide of an adjustable butt

Once I finalise the sizes I can generate 2d views to take into the shop. Seems pretty cool to me.

So far I've only managed to do this sort of simple model containing a single part. I haven't worked out how to create more complex models with multiple parts fitting together.

Jim

Thanks for pointing this software out. I have been a visio user for years and it has served well in my work but I think I could sure use some 3D capability so I will sure try this out.

I had a lot of problems when I got started with the current version (version 14) and when I asked on the forums I was recommended to try the not-yet-released next version. That fixed a lot of my problems, but it means that I'm working with a rather unstable work-in-progress version of the software. I'm told that the next release should be soonish, but I don't know if that's a weeks or months sort of deal. It seems to be mostly developed in Europe, so it works natively in mm. Support for inches was badly broken in version 14 which was frustrating. I nearly gave up on it, but they do seem to be making steady progress.

Could also check out LibreCAD and DraftSight....I like DraftSight as it's very similar to AutoCAD....only 2d, but good'nuff for construction drawings.

I use draft sight for my plasma stuff. Really like the flow of it....but as was mentioned it is 2d only.

Laugh if you must, but I've been using the "free" version of SketchUp with great success for about a year now (once you learn how to use it). Does everything I need - 2D, 3D, 360* viewing, solid view, ghost view, etc, etc...

I use to use AutoCad to draw house blueprints as a side job, but when my computer crashed (and didn't have the coin for a new drafting program) I thought I would give SketchUp a try. I'm no computer whiz so it took me a bit to get the hang of it, but I don't think(?) there is much that SketchUp can't do compared to AutoCad.

Just a quick example of one of the projects I'm working on using SketchUp(no copying!! :lol: ):

Hey Todd, that looks great - both from a software and an airgun point of view! I've been thinking of trying a sidelever breech - I hope you don't think I'm copying if I ever get around to making it!

I'm currently doing one that takes the marauder mags, with a normal bolt action. It's at the working-but-ugly stage right now. I've got a chamfering cutter on order, so when that arrives I'll face up the top and sides (currently still mill finish :oops: ) and put a bevel around it. A coat of paint and it should look half decent, and it sure is fun to use. The marauder mags are great, but it's a bit too easy to double feed pellets. If you hesitate during cocking, or your finger slips off the bolt you can be left unsure of whether you've chambered a round or not. Worse is if the second pellet gets stuck half in and half out of the barrel, locking the magazine in place :shock: That wasn't a whole lot of fun, and is what got me thinking about a sidelever - less chance of a half-cock, so to speak.

I remember now why I passed over sketchup when I was looking for software - they only mention Windows and Mac versions, and I wanted something for Linux. I may have to re-think that one, as sketchup looks a lot more finished than FreeCAD. Still, it's doing the job so far. Got to see if I can put more than one part into a model so that I can see how things fit together.
