Change "Part" to "Assembly" in your equation.

Note that this only works for versions up to whatever you have installed. If you're running 2016 and you try to look at a 2018 file, it will only tell you "future version".

Good grief guys. This has never been true for SolidWorks files. There used to be a numerical code buried in the file (not in the header) that you could use to look up which version the file was saved in. You could also find readable text strings such as all the custom properties and their...

The diagram on the data sheet shows you how it's done, if you can read it. See attached pic... During vacuum generation, high pressure air is supplied through port 1, and vacuum is generated at port 2. Additionally, a small internal reservoir fills with pressurized air. This air cannot reach...

What in the actual heck do you mean by the arctangent of 1/32rad? You can't find the arctangent of an angle. However, the way that SolidWorks is ATTEMPTING to interpret your PEBCAK is by first translating your specified value of 1/32rad into the units specified in "Angular equation units" at...

No change since 2004, other than the ability to customize the location of the file. faq559-1052

This is built in to SolidWorks. Just click the "More symbols" button and you can see the entire library. To get the string for any symbol, just hover over it.

Please watch this video to gain a bit of understanding about Bezier curves and splines: https://www.youtube.com/watch?v=aVwxzDHniEw There is not an "equation" for the spline.

It's obvious that the thing on the right is a gear that rotates about the shaft. It is drawn as a gear, with those centerlines showing the pitch circle diameter. The shaft is clamped tightly to the housing on the left by a locking nut. On the right, there is certainly a bushing for rotation...

This is the proper way to lap steel: https://www.youtube.com/watch?v=2QhYXd9AsPU

My guess is it's seen by current mgt as advertising a competing forum.

No worries... There are so many sections in the SW online help, and it's not immediately apparent where you are, especially if you arrive on a page via a Google search or something.

I know this is late, but just for completeness... The base is not 16, it's e. SolidWorks equations use the VBA log function, which is the natural logarithm. Please see https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/log-function As noted in the link above...

Assuming you are controlling them properly, hydraulic cylinders can stop at any point in the stroke at any time without hitting an internal or external stop. As soon as you close the valve, incompressible fluid is trapped on both sides of the piston and the movement stops.

Start a new part. Edit the lights. Save as part template (.prtdot). Use this template when starting new parts.

Coincident mate between the two coordinate systems, with the "Align axes" option checked. Sounds like you need to complete the tutorials. This is beyond basic in SW as well.

I interpret the picture as an attempt to sketch up one of these.

This gets me there: https://r1132100503382-eu1-3dswym.3dexperience.3ds.com/#community:yUw32GbYTEqKdgY7-jbZPg At least it's an easy URL to remember... [banghead]

We don't do your homework for you. Just posting your project requirements will not get you anywhere. We may help if you have specific questions. What have you done so far? Where are you stuck?

OK... Just for the sake of numbers, let's ignore all the internal friction and just consider the friction of the input and output bearing/seals. Let's say each one has a friction torque by itself of 1Ncm. So, you grab S1 and spin it. You will feel 1Ncm resistance from S1's seal, and 0.1Ncm...
