Carrie is getting closer to what I had in mind. Model organization is vital regardless of platform.

Assembly design techniques also are a good example. Top-down design and in-context design principles are universal. So is use of layout sketches.

I've used NX, Creo, and SolidWorks for complete product designs. I've learned and re-learned different CAD systems multiple times, as well as troubleshooting issues in other CAD systems and neutral formats. One thing that has allowed me to switch readily between CAD systems is an understanding of &q...

What should go into a book about CAD that is CAD-agnostic? What principles transcend CAD applications?

I know I'm sounding obtuse if not outright belligerent. In practice, I do actually do these things, but with my best Midwest-nice demeanor. But I stand firm.

the "drawing" is coming from the Marketing & Public Relations department I would cease all communications with them other than " connect me with someone who knows what they're doing ". I've been through this spin cycle way too many times. A 2-minute conversation or one-line ...

If you want to use sound files, you would do well to learn about resource modules in VB. A resource module lets you store files for access by the program, without having to have the file reside at a specific address on your drive. disclaimer: My API kung fu is old. This is VB6 or VBA circa 2010. It ...

I would just kick it back and insist on a dxf (or at least STEP). They need to learn appropriate formats for manufacturing, and (hopefully) pass this knowledge on to their students. Seems ridiculous that they took the time to give you another useless export but didn't take the time to give you somet...

e.g. SolidWorks has multiple sub-fora. If I want to go from "How to" to "API", it takes multiple steps. Clicking is hard. Wears out the internet faster.

I'd give them more like 3 months. Especially any European users who have the luxury of extended vacations.

There's a trick to going up the chromatic scale. Each half-step's frequency is 2^(1/12) times greater than the previous. You can extend this ad infinitum. Take A=440Hz B is two half-steps higher --> B = A * 2^( 2 /12) C is 3 half-steps greater --> C = A * 2^( 3 /12) Note an octave's frequency is dou...

I've done top-down design in SolidWorks, Creo, and NX. In spite of their differences, the methods are pretty much the same.

What are you doing that doesn't work?

HerrTick

Faster way to collect interior surfaces is to copy the solid body and use Delete Face to remove the top edge. This is useful if there are a lot of small faces to collect on the interior.

HerrTick

It's no more or less useful than a college degree.

My BSME has been very useful, while getting SW certification will yield no tangible benefit.

I'm not sure the certification is on the same level as a college degree.

I am certain it is not.

HerrTick

It seems most (all so far) CAD rebuild processes do not lend themselves to multithreading. The same is true for FEA solvers.

HerrTick

I change sketch default colors so that constrained entities are dark green instead of black. Helps sort out active sketch vs the rest of the black line clutter.

HerrTick

This is something to watch out for. SW drawing views default to 2D if it is one of the principle views or a projection. Other views default to 3D. This can cause great heartache for those caught unaware. I made an addin a long time ago to address this issue, as it caused no small amount of trouble a...

I like to use "dusty pastels" for the largest pieces. A quick adjustment in HSV mode to mute hue and add chalkiness. Makes things easier on the eyes.

Bold colors for small parts that are harder to find.

HerrTick

SolidWorks lets you play. Creo lets you play doctor. NX lets you play god.

HerrTick

NX is only suitable if you need to do more, better.

John McEleny is making money with OnShape. No surprise there.

HerrTick

Can this be fixed with a change of script?

HerrTick

Needed to rotate a line of fixed length about an axis until the end met another line. Simple enough in SW. In NX, it involv3ed making a temporary surface to find intersection of line axis and cone face. I turn off nearly all automatic constraints and dimensions in sketches (in SW and NX). Automatic ...

Helps to have custom properties for source and source p/n. sometimes. We did that when Endries was the in-house supplier, guess the number of non-value-added hours spent updating stuff and how many were missed when Purchasing decided to switch to Fastenal. Firstly, I would consider that properties ...

Also, there's no way to move a thread to a more appropriate category once it's posted. Maybe a good thing? But I wish I posted this in the "What's wrong" forum.

Sorry. There was a typo. Bullet lists SUUUUUUUCK! Just try and use them and come to a different conclusion. If you select multiple lines (each terminated with a return), only the top line is bulleted. I had to select each line individually to make a decent looking list. Don't even want to know how a...

also not clicking this link. Not clicking unmarked links in posts with no other explanation. aAlso maybe we need a preview function.

HerrTick

Great add, Mark. Many thanks.

There's also an important topology lesson there. SW and the parasolid kernel hate hate HATE when things ALMOST match. The replace face trick turns an *almost* into an EXACT match.

Sometimes STEP export turns planes and revolves into B-surfaces. That sucks, but there's a simple, stupid fix:
Export as STEP203 and reimport. Often this re-translates the B-surfaces into revolves and planes. Why? I don't know.

This also works on other CAD platforms. Used this is NX recently.

HerrTick

Split revolves are endemic to STEP, especially from Creo. Per Matt, Delete Face usually fixes. Sometimes Replace Face works when Delete Face does not. Sometimes STEP export turns planes and revolves into B-surfaces. That sucks, but there's a simple, stupid fix: Export as STEP203 and reimport. Often ...

HerrTick

I don't consider the two-cylinder shape a genuine zero-thickness problem. It's just two pieces.

HerrTick

Boolean the hard way!

Got a feature that absolutely refuses to unite/subtract/intersect? Turn the solids into surfaces using Delete Face or other means. Trim pieces to match. Then knit into a solid.

The true miracle is that SW will recognize the result as the same solid after the knit operation.

HerrTick

Had potential to be a decent product. Instead it turned into a great story.

HerrTick

There's a subscription? That's creepy.

SW forum was moderating 100% of my posts last week. I think they were mad about the Parler remark.

Happened on submission, but went away when I retried.

If I have a primary symmetry plane, I rename it with "SYMMETRY" in the name (yes, all caps). It helps me. It helps others. I've had people thank me for it.

How can I make #8000FF my default font color?

My best disaster! Great design work and a great team overcoming great challenges, torpedoed at the 11th hour by an overzealous founder with an itchy trigger finger.

The only semi-legit cases for t=0 geometry I can think of...

I prefer multi-body for PCBs so nothing gets lost. Most of the geometry is simple enough that even large PCBs don't cause too much trouble. I have yet to work at a place that maintained a component library well enough to make good use of PCB Exchange interoperability. (Some "heavy-hitters"...
