I have a problem with the equation function in SolidWorks, the problem is simply that I cannot create any equation driven dimension!

I can open the equation tool but that’s about it. SW response to any simple equation is that I got the syntax wrong.

__I use SolidWorks 2003 version.__

My steps in more detail below:

1. I open a new sketch

2. I make a simple rectangle

3. I give a dimension to the two of the sides of the rectangle, SolidWorks automatically name the two dimensions D1 and D2

4. I click “Equations” in the “tools”-menu

5. I click “Add…” in the window that then opens

6. I get up the window where you can enter you equation

7. I click on one dimension, for example the D1 and SolidWorks then automatically fills in "[email protected]"

8. I then click the equal sign (with a space before and after) using the number and operator buttons to the left in the window)

9. Then I test different things e.g. clicking on the D2 dimension so that it says "[email protected]" = "[email protected]" or adds "[email protected]" = "[email protected]" * 2 or simply "[email protected]" = 5 or something else then I click “ok”

10. No matter what kind of equation I enter I get a window up saying

__“The syntax of this equation is incorrect”__after having pushed the “ok” button in the previous step! Slightly frustration

I assume that the left hand of the equal sign is the dimension that you want to assign a value and the right hand of the equal sign is defining/assigning this value, thus the “formula” should be on the right hand side.

I hope that someone could point out my error.

**It's so basic that either I am doing something fundamentally wrong or it’s a freak thing.**
