Thank you,

when you say "projected origin" do you mean the centre dot that is at the 0 point on a blank new window?

I will try again to start a new one from scratch right now and post it up when done

Yes, that is what I mean.

After we go through this - you will see that it is trivially easy once you know what you are doing.

ok,

I have just started and I want to work something out.

I make a rectangle 2 different ways,

1/The first way is just drag out a 2 point centre rectangle and place it with the mouse at the measurements I want.

something I notice when i do this and then later want to set up parameters, I cant get the Height (z axis in the attached file REV1)

It gets reall stange and give me a wacky angle at the top..

 

the second way is , I start the 2point centre rectange with a click and then key in the desired dimensions manualy,

This lets me keep those dimensions and so I can set up parameters linked to those measurments... which is vital for what I want to do with these joints..

 

in the first scenario if I use the dimensions tool in /sketch and put in a measurement longways on that rectangle, I get a driven dimension.

I can't change a driven dimension, so I am stuck.. 

 

I know to do it the second way and that will prevent any problems, but what is a curative remedy for this kind of problem, incase I find out later in the process or as my previous post outlined where I couldn't find the dimension for the other piece of the join he uploaded.

 

I really appriciate the help.

Rev1

This angle dimension is completely meaningless.

Right click on the sketch in the browser and select Edit Sketch.

Then click on this dimension and delete it.

You do not care what that angle is.

The only thing you care about is the width and height of the rectangle.

I'm sorry, I didn't mean to say this was solved..

https://www.youtube.com/watch?v=XkJ5GmP-ksE
this movie shows the tool I want to make, and can make following these instructions
http://www.widom-assoc.com/MA319-5_The_Sharpest_Tool_For_Woodworking.pdf

if it's so easy then could you show me a working example of this tool.
in a file please.

Go to the Top view and start a New Sketch on the top face.

 

Select Project Geometry and click the edge shown.  (My guess is that you did not read the document I linked earlier - in which case Inventor already projected this edge - so you can skip the Project Geometry if it is already projected.)

Sketch a horizontal line being sure to select the midpoint of the vertical line as the first point of the line.

Window select all of the lines and click the Construction icon as shown.  This will convert your lines to dashed construction lines.

The big question is where in revA is the Z axis projected to? because it isn't showing up for me can you find out,

And then in that same file I want you to type 3000mm into user parameters with the word (BIGGER) and then I want you to the sketch and change the

Z axis measurement of that rectangle to the user parameter just by using the word BIGGER.

I want you to simply do that and send me the edit, maybe then I can see
