Tutorial Problem

I'm still going through the tutorial.  I'm only on Create the part from Scratch.  Obviously I have Options not setup as in the tutorial because simple thing lile the coordinate system indicator was on in Sketch and preventing me from picking the 0,0,0 point.  When I try to add a constraint to my rectangle to center it over 0,0,0 it gives me a message that it would be overconstrained and won't do it.  I can go on and add equations to the general dimension.  But the simple task of constraining isn't working.  I've gone back to the Constraining exercises but it won't work for me here....

What do I have to do to make this centre over the axis??

Following the steps in the Tutorial -

 

On the Constraints tab click Horizontal

then click point 1 (the green projected origin) and point 2 then midpoint of the left vertical line.
What happens?

I followed the video pausing at every step to check the messages against what I get.  As soon as I pick a line on the rectangle, right away a message of overconstraining comes up.  I started over 4 times with the same results every time.

It must be something in the setup of Inventor or Inventor Options that is doing this.

It's a really simple task and it's really bothering me that I can't do it.

Have you closed Inventor and restarted?

I changed a setting in Inventor/Options/Sketch: Overconstrained dimensions to Apply driven dimension.  Re-started Inventor, new part created with the same template.  As soon as I click on the line on the rectangle the message window appears: "Autodesk Inventor- Create Constraint: Cannot constrain or dimension reference or fixed geometry".

I edited the sketch on the part you posted with no problems. 

 

Not sure why you are having this problem.

It sounds like you are clicking twice on projected geometry.

This is what I have been doing, over and over:

 

I start a new part, it opens up in sketch mode already and I click on rectangle, pick two points  across for the latter, hit ESC, then horizontal constraint, I then pick the 0,0,0 location, then a vertical line on the rectangle and bang the message window appears.  I just don’t know what it coud be…

When creating the rectangle, do any constraint glyphs (horizontal, vertical) appear?  After placing a rectangle, what results when selecting autoconstraints?
