Deepak Gupta May 27, 2010 10:12 AM (in response to Daniel Johnson)That option is not available in SW. But you can use Equation (Tools > Equations) for the same purpose.

Re: How to show equation (not computed) in dimension?
Charles Culp May 27, 2010 10:14 AM (in response to Daniel Johnson)when typing in the number (or equation), you will notice an arrow to the right of the text box. Click on this to see a drop box of options. One of those is Equation... where you can write out the equation, and it will save it. You can then see all your equations directly in the feature tree, which will show up with a Sigma symbol and labeled "equations".

Daniel Johnson May 27, 2010 10:23 AM (in response to Charles Culp)Thanks guys. These things are second nature for me in Inventor but I have to identify the SW approach, workflow, etc.

Re: How to show equation (not computed) in dimension?
Deepak Gupta May 27, 2010 10:30 AM (in response to Daniel Johnson)Dan, being used Inventor for quite some time,. I know this is a really option in there. But again then using equations in SW is giving you the same thing but in different fashion.
You might also want to look at these posts (which discussion about linking dimensions using different methods):

Re: How to show equation (not computed) in dimension?
Daniel Johnson May 27, 2010 10:37 AM (in response to Charles Culp)How do I place one of these predefined equations into the extrude box? I've noticed the same arrow isn't there and it won't allow me to just type in the name of the equation.

Re: How to show equation (not computed) in dimension?
Jeremy Feist May 27, 2010 10:43 AM (in response to Daniel Johnson)For the extrude depth and similar features, you can only add an equation after the feature is created. you can have SW do math in that box, but I would just put in a dummy number. and then double click on the dimension and you get the usual edit bim box with the dropdown arrow to add the equation.

Re: How to show equation (not computed) in dimension?
Daniel Johnson May 27, 2010 10:51 AM (in response to Jeremy Feist)I'm not seeing a dimension for the extrusion distance. The only dimensions I can see are the ones in my original 2D sketch...

Re: How to show equation (not computed) in dimension?
Brian Place May 27, 2010 11:01 AM (in response to Daniel Johnson)try double clicking on the extruded part and it should show that dimension

Re: How to show equation (not computed) in dimension?
Daniel Johnson May 27, 2010 11:07 AM (in response to Brian Place)It shows the dimension, but the edit box looks different than the one I see when editing a dimension inside a sketch (i.e. there is no pulldown box with the option to link it to an equation. How can I get the extrusion to be linked to an equation?


Re: How to show equation (not computed) in dimension?
Charles Culp May 27, 2010 11:07 AM (in response to Daniel Johnson)Daniel,
I have attached a video I created (only works in IE, not Firefox, sorry. I will create a vimeo account tonight and embed it directly in this post when I get a chance). It shows how to do this.
I will have to narrate here, there is no sound in the video. I used the "S" key for the shortcut toolbar to use the extrude command. Half way through, I double click on the feature to get the dimension to show up (in blue). Also, at the end, I hit CTRLB, which is the shortcut key for rebuild. Because I set the screen to so small, I no longer have the rebuild button visible.

Charles Culp May 27, 2010 11:26 AM (in response to Daniel Johnson)Here is another copy using regular compresson. It looks like junk, it is washed out, squeezed to fit, and has a bunch of artifacts, but maybe you can still see what is going on.

Re: How to show equation (not computed) in dimension?
David Miller May 27, 2010 10:21 AM (in response to Daniel Johnson)I do this all the time. One of the easist things to do is double click the dimension that has an equation attached to it and select edit equation.
One other thing I do, particularly since alot of dimensions are driven by either mechanical or thermal design is to embedd the equations in a design table. If you know how to add dimensions to a design table, add the dimension you want to be driven by equations into the design table and then use excel formulas to provide the value you want the dimension to be.

Re: How to show equation (not computed) in dimension?
James Preston May 27, 2010 11:12 AM (in response to Daniel Johnson)Also you can Add any notes after the equations you must put it in after the ((sketch@D1 = "A/3")) say this is the equation, you can add any kind of notes after this " mark SW will not do anything after the " Symbols. Hope this helps? Good luck.
