Length

So I was building my robot on Autodesk Inventor. I looked at the space between the lift (where my stuff would be) and it was about 15 holes wide. How long is that.

7.5 inches or 19.05 centimeters.
Each set of 5 holes is 2.5 inches.

ok thank you

@985C_Robohawks Just in case you need another measurement, and you don’t want to wait for the forum for help, I suggest you learn how to use the measure tool in inventor. Here a link to a guide about how to use it: https://knowledge.autodesk.com/support/inventor-products/learn-explore/caas/CloudHelp/cloudhelp/2014/ENU/Inventor/files/GUID-04C0E113-3922-468C-8779-23A171E55F93-htm.html.

I feel that is an essential feature of inventor, and I find myself using it frequently.

Just press M anywhere in an assembly, and connect two points.

For some reason mine won’t measure.
