Solidworks - Equations and Linked Dimensions

CatFromHue

Hi, just wondering does anyone use equations and linked dimensions in Solidworks.

I know how to use them and what they are for but have never used them.

I do use sketch constraints which seem to do almost the same as linked equations but the equations are a bit baffling.

I've been reading a Soildworks how to book and the section on equations isn't too detailed on why you should use them.

I've used these before in isolated cases, but like yourself mainly use sketch constraints.

According to the Solidworks training blurb I have, equations are used when you can't use sketch constraints or other tools. I think the real use is in design table-driven or multiple configuration parts, but I don't use these often.

I used them just today. I'm designing high voltage Rogowski electrode's, the equasions can be found here. Its not very often I have to use equations in modelling but from time to time with surface modelling they can be very beneficial.
In this case I have a few different size electrodes to design with a curve on the edges. The profile of the curve changes with the profile of the electrode and the distance each electrode is from its opposite. Rather than design each pair separately I design one and alter the diameter/distance for each different size electrode.

That's pretty cool stuff. What are you using these electrodes for (if you can say)?

The equations and sketch constraints are a really good way of showing design intent, i.e., how the dimensions relate to each other regardless of their values.

Its a monitoring device for measuring high voltage power factor. I cant say much more at the minute Im afraid.
