# Goal Seeking in Solid Edge

This comment from Dan Lanigan reminded me of something that I had promised myself to do but never actually got down to doing it – learn more about the Goal Seek feature of Solid Edge. So this morning I fired up Solid Edge ST2 and searched the product documentation for a tutorial on Goal Seek. I found one and carried out the simple steps to complete it.

Since the interest in Goal Seek emanated from my article on GrafiCalc, a software whose main purpose is goal seeking, I decided to try out the two circle problem I mentioned in that article. The problem is as follows:

“Given two intersecting circles A and B, what is the radius of circle A so that the area of intersection of the two circles is equal to half the area of circle B?”

I sketched two circles and dimensioned them as necessary.

As you can see in the figure above, the area of the circle on the right (Right Area) is 314.16. I now needed to calculate the radius (R1) of the left circle so that the area of intersection of the two circles (Middle Area) equals half of Right Area. This video shows how the Goal Seek feature of Solid Edge did it for me in a jiffy.

One small problem is that Solid Edge did not allow me to enter an expression for the target value. I needed to enter numbers only. It would have been nice to enter 0.5 times Right Area or pick a value from the graphics window, instead of entering 157.08. But that’s not a big deal. The point is that Solid Edge found a solution for me almost instantly.

If you are interested you can download a white paper written by Siemens PLM called “Goal Seeking in Solid Edge“.

If your interested in this you can also have a look on http://bit.ly/c3OQcO on the right hand side under the “Process Specific Applications” you will find a film showing goal seeking in Solid Edge.

• Funny – I saw this post and just wondered when it was introduced – I found an old review I wrote nearly 3 years ago (pre DEVELOP3D) on an Edge resellers' website.. http://www.solidapps.co.uk/PLM_Express/PLM_Expr

Blast from the past.. But this tool is damned impressive but, as ever with many things Solid Edge related, it never gets talked about.. It's not for want of trying from the Siemens guys (and this has improved a lot since the Siemens acquisition), but its still a best kept secret..

• Deelip,

Good write up on Goal Seek featuring a good example. Another favorite is how Goal Seek can determine pulley locations given a fixed belt length.

Not sure if you knew this, but we also offer Goal Seek in Solid Edge 2D Drafting, a free 2D program that can be downloaded today. Here’s the link
