Need some ideas from the braintrust for a really cool project!
Happy Sunday, fellow SolidWorxians.
I'm a bit of a geeky guy, and like to follow the site https://hackaday.com/ for amusement purposes.
While perusing through some of the articles, I came across this: https://www.decarpentier.nl/carpentopod#comment-5654
Holy, shazbot, Batman! That's REALLY cool, beyond cool, cold, frozen.... LOL!
Anywho, I was sufficiently motivated enough to put the eleventy-seven other projects I'm working on aside, and replicate his work in SolidWorks. Fairly straightforward, there are a couple of nuances that took a wee bit of thinking, but here it is, at least one of the six "legs"
I'd like to try to 3D print up one of these to futz around with it. Trouble is the individual pieces are quite a bit larger than my printer. So I thought I would try scaling everything. That seemed to work fine. The challenge is there are some 8 unique pieces in the assembly, and tweaking the scale on each one is a tad tedious.
So, I thought I would drive this with an equation, right? That's what they are for. Trouble is, SolidWorks doesn't provide the ability to do so.
I did some looking around and yea verily this feature is not available.
If push comes to shove, I'll write a macro, but that seems like a brute force solution to the problem.
I'd love to hear any ideas from the braintrust on an elegant way of scaling this thing down (or potentially up!)
The unfortunate part of all this, is it has REALLY whetted my appetite for a CNC router. Damn, another rabbit hole.....
thanks all!

When I need to print parts larger than my print bed, I use dovetails. With a little tweaking, you can get a fit that can be pushed together, but doesn't require adhesive.

Re: Need some ideas from the braintrust for a really cool project!
Why not just finish them with the scale feature and then tweak it from there? Shouldn't be that demanding to tweak around 8 objects..?
Re: Need some ideas from the braintrust for a really cool project!
Does your 3D print software offer scaling? I've been using GrabCAD Print and it's got a lot of post processing tools that can help.
Select all bodies and scale all at once. Edit: Aside from that, I remember a macro floating around that scaled all dimensions in the model by your scale so it was true to size and not using the "Scale" feature to modify the body size. I don't know if I'll be able to find it though.

Yeah, Cura does do scaling. Good Idea.AlexB wrote: ↑Mon Sep 16, 2024 8:33 am Does your 3D print software offer scaling? I've been using GrabCAD Print and it's got a lot of post processing tools that can help.

I would like to see the macro if'n you can lay your hands on it.

I think that at the end of the day, this is prolly the best solution.AlexLachance wrote: ↑Mon Sep 16, 2024 8:28 am Why not just finish them with the scale feature and then tweak it from there? Shouldn't be that demanding to tweak around 8 objects..?
The challenge is designing these bits and bobs so that I can actually manufacture them with the limited capability at my disposal.
I wouldn't even begin to attempt to build a full sized-ish version of this with some sort of automation, hence the CNC router.
That's not going to happen in the sort term, so when it does deal with it then.
Cheers

Model them at correct size.
Scale will change radius and holes size. Also clearance between parts.
It's difficult to scale a drill down.

I believe it's ModelRescaler in this list of Lenny's tools: http://www.lennyworks.com/solidworks/default.asp?ID=20

I haven't thought about usenet newsgroups in a couple of decades.RotateViewPro is a simple SolidWorks macro that is based on a recent request for help found on the usenet newsgroup "comp.cad.solidworks".

Whoa,
I thought Google killed usenet....
Was a faithful denizen at one point, a long time ago.

Awesome.
Most of the macro's have been removed, but a long time ago I grabbed the entire lot.
It's called ModelRescaler.
Now let's see if it still works.
cheers

Wow.
Still works.
Had to make one variable declaration.
I've attached a copy if anyone wants to try it out.
