Draw-in sounds like a simple distance, but we still need to define what we measure from and how. In PAMSTAMP, draw-in profiles are projected onto the die surface and their lengths are calculated there.
So don’t assume the value is just the straight distance you could draw over a top-view screenshot.
Show the reference with the draw-in lines
Open Draw-in in postprocessing and select the die and blank. The reference can be a blank contour from a selected state, a 3D curve, drawbeads or a die-entry line.
Display the Reference normal and measuring direction with the model. These control how the profiles are constructed and projected.
Start with a few recognisable positions. Create the lines manually or use the automatic plane controls, then click Compute. Follow them from one boundary to the other.
Do they describe the measurement you intended? If you change the reference or blank, compute again. Keep the same plane and direction definitions when comparing runs.
Take a section through the interesting area
Create and name a plane in Section Planes. Put it through the region you want to inspect.
New Contour Cut can plot a contour value along that section or the section geometry itself. For a curvilinear path, choose the starting point and look at the direction arrow. Reverse it if necessary.
Knowing which end the curve starts from makes a later comparison much less confusing.
What should the caption say?
For draw-in, give the state, reference and measuring direction. For a section, identify the plane and path direction.
Some section displays use line thickness to exaggerate a contour. Explain that if you use it; otherwise, someone may read the display as literal sheet thickness.
I would show a few clear measurements in the post and keep the full data with the study. A screen full of overlapping annotations usually makes a simple explanation harder to follow.
