How to dimension a curve on an interval

[mcenhillk]

I got a work around to this problem from a user on Reddit. However, the solution we came up with doesn't seem "right".

The project is cutting out a shallow arc from a large piece of foam. I've included a screenshot of the drawing where I got stuck. What I'm trying to do is dimension the height of the curve relative to the bottom of the body at a regular interval along the x-axis, every 12" would be enough. I've tried adding construction lines and points to the sketch in the design space but none of those are carried along with the body when I make the drawing. The hack that eventually worked was to create extruded individual bodies 12" wide in the design space and use that segmented body to give me edges in the drawing space to dimension. This seems inherently wrong. Yes, I got the result I wanted but I had to modify the model to make the dimensioning work in the drawing. 

So, how do I dimension the height of a continuous curve at regular intervals in a drawing?

Though it may be tedious, what I have had to do in the past in my 2D program because it does not offer a lot of functions and I work with features like this as well, I have gone along the x-axis every 12 inches, drawn a straight line up to the curve, then drawn a three point arc from the first 12 inch line to the second 12 inch line and using the center between the two lines as the third point.

Hi,

please share the file and a screenshot showing the segments.

I assume, correctly I hope, that you intend to hand-cut? The drawing environment may help in this case I simply created 1300+ 1X1" Bodies via a Rectangular pattern then dis a Combine intersect. 

my y axis count/distance was slightly incorrect but it may even of helped!

I have attached a screencast showing what I meant. Since, obviously there is no radius given, I made a random dimension there, but I showed the workaround I have to use in my 2D software since it doesn't have the capabilities that Fusion has.

Corrected.

when ever you need to dimension somewhere along an edge, splitting a face adjacent to the edge will give you a point on the edge to dimension to.

you can also use the sketch method.  model sketches can now be displayed on drawings and dimensioned to.

Simply draw a line from the baseline higher than the curve. Rectangular copy it. Trim all of the lines above the curve.  Create your Drawing.  Include the sketch in the Drawing. Dimension the lines.  Unfortunately you can't use construction lines in the sketch.

Sorry for the late reply. This is a hobby project so I don't always have the time I want to spend on modeling.

Thanks for all of the suggestions. I missed that the sketch was included in the drawing. That solved my problem. Now I don't have to model the object differently if I want to document it in a drawing.
