Binding dimension of the middle line in the sketch without constructing points

Status: New Idea

Hello When you create, you can choose constraint to the midpoint of the line, and when you put dimension is impossible. Why not do it for dimension.

 Not really needed...


 What are you doing that needs this? Do you do it often?


 You can always use the center point and place it at the midpoint of the line so you can do this..

Let Autodesk decides it is necessary or not.

I do not have to think about it. My job is to suggest an idea.

Sure you have to think about it.


 They want ideas that have been thought out not oh I tried to dimension to a mid line and can't so I have an idea... Can you imagine the ideas that would be posted if it was not thought out? Or ask how others do it?


 In all the years of using Inventor I might have done that one or two times and it was easy to put a point on it and go..


Even in Autocad I might have done it one or two times...


Just trying to understand why.. In all the years not one has even asked how come they can't do this...

Niksasa, Try using the "rectangle two points from center".  That will automatcially give you a centerpoint to dimension from, but honostly I don't know why you couldn't just dimension from corner to corner.  It will still be 10.

In solidworks has a team of "select midpoint." Why autodesk this a problem?

Go use Solidworks.


 For all the years of Inventor this was never needed.........


 There are so many was to do this you don't need a midpoint.

Not sure why y'all're assuming that rectangles are the only time you'd ever want to dimension from the midpoint of something ... 


I've got a project I'm working on right now where this would be useful.  I've got to lay out a bunch of ribs on something, and their location is dependant upon the midpoint of something else.  Yes, I can manually add a centerpoint, or I can add construction geometry to do it, but it would be quicker to just dimension off the midpoint of a projected line.

I've seen cases as well where I could have used something like this (locating slots, cutouts in plates, etc.).  It is true that it wouldn't introduce anything you can't currently do with existing tools.  I see it as more of a time/click-saving feature, eliminating the need for seperately adding a point to dimension to.


The OP mentioned the fact that some constraints already behave this way (Horizontal and Vertical constraints come to mind).  They do this currently by automatically adding a point coincident to the line's midpoint, essentially automating the manual process of adding a point and constraining to it.


Making these two sketch processes behave similarly, and eliminating a few clicks here and there, sounds like a good thing to me.
