Using Driven dimension

Anonymous — Wed, 20 Jan 2016 11:27:24 GMT

Hi, there!

Let's say I have a hexagon with green dimension size.

But I want to use the blue dimension, for example, for calculating the height of another object.

Inventor sets this dimension as driven and it doesn't have a name in order to use it somewhere else.

How do I solve this issue?

Thanks!

the file is attached

go into your FX ....

it's in the reference Parameters...

You can use the D1 value.

You can simply click on that dimension to use in a dimension/equation, you don't really have to go into the Parameters.

You can also change your dimension display from the default 'Tolerance' to 'Expression', which will always display the parameter name. Right click in the background of a part and select Dimension Display, or use the third icon at the bottom of the screen when editing a sketch.

It might also be worth noting to beginners that a variable name D1 is not the same as variable d1 (variable names are case sensitive, you could have two variables, d1 and D1).

Glad it helped. @JDMather's advice is also helpful, but I think that you didn't understand what he wrote, so I'll try:

As long as the reference dimension (or any other dimension, for that matter) is visible on the screen, you don't need to know it's parameter name in order to use it in another parameter, you just pick it with your mouse to include in an equation. You can also display hidden sketch dimensions while editing a dimension by using the little arrow to the right, selecting Show Dimensions, and picking on the feature defined by those dimensions (see below).
