Does anyone here have experience with using dry gas / cavity decay test instead of presurized water to leak test pumps with rotating mechanical seals?
Thanks,
I'm doing a tolerance stackup of an assembly with tolerance rings to fit bearings in a bores, one manufacturer is here:

Does anyone have experience with how much they affect the conecentricity of the bearing with the bore?
TIA
Is anyone familiar with the SWX Tolanalyst?
I want to do a stackup study with a pump assembly and I'm curious how it works with multiple supports on a bar (shaft in this case)
For discussion of the primary matter of this thread, but the stubborn dissagreements can remain there.

The drafting standard where I work doesn't use the phi symbol in diameter dimensions and I'm trying to find out how to remove it from a dimension in AutoCAD LT.
I'm working with castings, so I have a drawing made of the casting, and then a drawing of various machined parts from the same casting. WIth the castign dwg, when I section the casting, I can exclude the ribs of the casting from the section.
The machined parts are a derived part, so the first...
In the US, crazy rents, tuitions and static wages are driving lots of people, some that I know to convert and live in vehicles like vans, RV's station wagons etc. The bay area of CA is a prime example.
I'm curious about pursuing interior design work for people who do this. This might be as...
I'm working through the process of cleaning up after people ignorant of how SWX files need to be maintained with appropriate links to other files. The assembly and dwg files were just moved from work folders to the controlled folders without revising the links to the new file locations.

While I recover from (insurance approval pending) surgery, our IT guy will hopefully resolve the long standing reboot, SWX nuisance and stability issues on my workstation. If wiping it and reinstalling everything doesn't fix it, hardware is next.

I'm working on impellers, and fillets are almost always a problem. This fillet doesn't want to generate bigger than 1/16th, where 1/8th is required.
Does anyone know tricks to get them to work? https://files.engineering.com/getfile.aspx?folder=f96224a9-6892-429f-b816-3ce3dc002101&file=fillet.JPG
Is there any way to do this? I've dried and I can only make a new set of views and add dimensions in.
One thought I just had was making a few in context sketches in the assembly and then automatically inserting model items into the views.
The best thing I can think of would be to have a...
A friend of mine is modifying a 99 Ford E350 van for use as a living space, because they think life as a renter is crazy if you go to Berkely. Reading the papers and hearing what their rent is, I can't argue.
Anyways, they've expressed concern about CG migrating up, how to calculate it...
Is anyone familiar with the history and origin of the english term in hydraulics 'Slave Cylinder'? I got curious in part because the term used by Mercedes, at least was not analogous in other languages- translating roughly to 'Taker Cylinder' in German and 'Clutch Receiver' in French and...

Preference where I work is for:
Aligned text on vertical dimensions
Use of 'DIA' after the dim value instead of phi symbol before
Use of R after dim value instead of before.
It's tiresome to fix all of these once I lay them down, but I can't find where to set the preference. Where's DIMSTYLE...
