You'll probably need to use Blender to split the bottom and top and scale the bottom, then combine them again.

You may be able to do this in Windows 3D Builder, but I'm not sure how precise its scaling is. It'll be hard to get center points because an STL file doesn't have arcs, just interpolated polygons.

I would probably ping the creator and see if they can even give you a STEP file or something, they're much easier to work with.

Hey CAD people, help me out here.

I have this (https://www.thingiverse.com/thing:4345459) STL file that I need to make bigger as this shroud is made for a smaller fan.

I need to enlarge just the base of it so that the holes are roughly 3" apart from each other all the way around and not change the dimension of the mount on it.

What would be my best way to accomplish this?

Have a look at this and see if it'll do the trick. I can make adjustments pretty quickly if something doesn't seem quite right. It's kind of a kludge, but it's a kludge that should print just fine.

The much smarter version of me just realized exactly what you were doing this for. I'm running a short piece of the mounting plate right now to check the hole spacing against the E10 itself. Should have a yea/nay for you in about 20 minutes.

He's the rear end in a top hat that tells people to run CNC machine tools far faster than they should be run and dramatically decreasing the lifespan of any given tool he makes "recommendations" on (and also dramatically increasing the risks of injury if a failure occurs and tool/stock fly out of a given fixture).

But of course, he doesn't give a gently caress about tool lifespan, because he gets free tools for his endorsement of said tool.

Also he's a COVID-denier rear end in a top hat.

There's even bigger stuff!

I use AutoCAD Map and Civil 3D for land use for surveying and engineering. I also use a lot of GIS, but sometimes CAD is better, and it helps to use both (importing/exporting) to support each other.

Here's an example. This is called an "Alignment Sheet." It's a specialized strip-map of a section of a pipeline. This is about one mile of the line, showing what it crosses, the elevation profile, etc:



That sheet is one of dozens for that project. They were created using survey and topo data collected and queried through a database to drive CAD.

I've used GIS for almost 20 years, and AutoCAD for over 15. I don't know a thing about 3D printing, sorry.

Are there any recommendations for good Solidworks lessons/courses? I've been using it (and Inventor, plus a few others) for something like 15 years, but mostly as a machinist that occasionally needs to design and make jigs/fixtures/small projects.

I'm looking to improve my workflow, especially with assemblies. A few people have mentioned that the sign of a good designer is being able to change features early in the design tree and not have everything break down the line. I definitely need improvement in that area.

I'm willing to start from the beginning if there is a well-regarded series of courses. Plus, I'm pretty sure I can get my work to pay for it, so cheap isn't a requirement (but would be nice).

I'm studying for my first solidworks accreditation, specifically CSWA - Mechanical Design; seems extremely easy, but I know it's more about doing it the 'right' way than completing the test tasks but using whatever wack-rear end bad habits i've picked up over the years.
Some general questions for people who've done this before- how many certs do you have? how long did the overall process take you, and how much did it cost all in? how much of an aid has it been professionally (or how much has lacking them hurt you)?
Also, any resources/courses you can recommend here would be handy. I saw the Indeed tutorials posted above; plus there's SW's own tutorials, and I've got a copy of Paul Tran's SW2016 Advanced Techniques textbook, so I have plenty, but if you have a favourite, lemme hear it.

CSWA is basically "babby's first certification" in terms of Solidworks certifications for each section of Solidworks.

The CSWP is where things start getting serious, but they still have generous time limits.

Thanks for reminding me that I need to take my remaining certifications so I can get my CSWE.

As far as companies hiring people go, having these certificates just tells them "yup, this person knows how to use the software at X level". If you don't have a mechanical design degree to go with it (or however many years in a design position in a technical industry), though, it's just a pissing contest with other SW users. Kind of like getting certifications for each Microsoft Office program.

I don't remember the current stats, but having a CSWP puts you well above CSWA holders, and last I checked there were only about 5,304 CSWE people in the world.

I'm sure that number has gone up after SW made such a big deal about it at the last 3DEXPERIENCE World, and then gave everybody that attended free attempts to test up to CSWE until the end of July.

Side note, cheapest way to get vouchers is to sign up for 3DEXPERIENCE World events each year and pay for VIP access.

Edit: Figured out how to search certification levels.

I've got 4 certs, most of them are easy, but in my quest so far, the Mold Design test has had a bunch of technical issues, so I'd avoid it. I get to take them for free, so it's just annoying instead of annoying and expensive.

Most of them have been easy, only surfacing took two tries. I'm coming up on a third for mold design accompanied with a list of typos and error reports none of the other tests have thrown.

I have a salary bump attached to earning my CSWE and a few others, so that's nice. I'm working for a VAR, though, so my angle on this dangle is probably not the same as most in thread.

Rhino goons, I have a couple of basic questions maybe someone can help with. I have a mostly Solidworks/Onshape background so this stuff is a bit new to me.

1. Is there an option to disable selecting far side faces/edges/vertices when box or lasso selecting? I would like to just select items on the near side of the model sometimes.

2. With SubD objects, is there at way to push or pull selected faces/edges/vertices to a target surface? I have a model with some wavy underside, and I would like to select those areas and pull them flat to a known surface. Sort of like projecting a curve to a surface but moving points of a SubD object.

I'd definitely be interested in any details you're allowed to share. I've basically been my employer's in-house Solidworks professional user that has trained other employees on how to use it for the various product lines we develop designs on (and those guys go and test up to CSWP and then go find a job at other companies, so it's like a never-ending training/work session for me ) and once I get my CSWE and see about whatever other training/certifications there are for VAR employees I may see if I can dip my career into that side of things.

Honestly if you want to check out the VAR scene, go for it even right now. I had only touched SOLIDWORKS a little before I joined and had mostly just been freelancing using Fusion and Rhino, self and community taught.

The VAR stuff is pushing to 3DX in a big way right now which I hate because it's still not completely baked. That said, my customer interactions and trainings are exclusively about SWX.

1) not as far as I know, lasso and box have always been select everything

2) not sure if it'll work here but I usually flatten out things by rotating my part so what I want flat is along a coordinate axis plane and then using the scale slider on the gumball to scale the z height of my points to zero which makes them all planar normal to that axis if that makes sense.

how does the academic testing work, anyways? it sounds like it has to be administered/proctored by a school employee, so someone on the school's end would have to have actively applied to be a cert provider and actively be offering the tests, right? is there a way to get the free tests as a student without needing to have a teacher be on board for hosting the test? b/c i will absolutely take some night school/con-ed CAD course to become an Official Student again, if it means i can stack as many tests as i can in a semester, or whatever.

No.

Solidworks Certifications are 100% online. You can do them on any computer with Solidworks that you have access rights to that will allow you to install the Testing client.

https://www.solidworks.com/solidworks-certification-program

EDIT:

Get an EAA membership ($40/year), then download the Solidworks version available to members of that group. Then download and install the Tester client.

Practice with tutorials/etc., then pay for an exams. Take/pass the exam. Move on.

Each exam price varies (and Solidworks does do promotions occasionally, but you have to keep an eye out for them).

CSWA - Mechanical is $100 to take as of today.

i accidentally clicked into the provider application form, and this part is what made me unsure:


Certification Rules
As an Academic Certification Provider, you must read and agree to the following rules before offering the exam to students:

Provider agrees to check Virtual Tester account 10 business days before exam day to see if they have the credits they need for testing.*

Provider agrees to verify the testing environment 5 business days before exam day

Provider agrees to give the exam in a proctored setting. The proctor must be a school employee.*


if there's no enforcement or verification that providers are actually doing it that way, and if you can independently apply without having to go through a teacher or the specific named Provider, i guess it doesnt really matter

Quick CAD package question.

I'm looking to actually buy a CAD program for my personal business as I imagine I will actually be making money soon. Pretty much just need good solid modelling for engineering components, plastic parts, sheet metal, engineering drawings etc. I'm used to using Solidworks from the previous places I've worked but it's like $15k NZD here lol and there's just no way I can afford that or justify it in my case. I've never really tried any other programs but I was looking at either Fusion 360 or Onshape, any suggestions? I hate the idea of web based software or cloud poo poo which is an issue for both of them but perhaps less so for Fusion? It definitely seems that Fusion is better value of the two when you're paying for it but I don't know if the modelling tools are equally powerful across the two, never having used them. Stuff like CAM and simulation are nice to have but not really a requirement for me.
