The size of things with rounded corners. This is only an issue where the rounded corner is your measuring point, like the triangle shown, or a trapezoid or other multi-faceted shape.
And it can be a big issue if you are expecting the dimensions you see when you measure the cut path of a dimensional finished piece.
Figure 2
A triangle with 2" radius corners applied in Indesign. Indesign is still telling you it is 20" x 20" to that bounding box it has drawn.
Figure 3
If you actually draw that bounding box with the rectangle tool and click on it, the dimensions you get are 18.594" x 18.9521" That is significantly less than 20" x 20"
Now, Illustrator does do what you described, but that’s because, IMO, it is using an effect to round corners. So, not changing the measurement make sense. But, if you expand the shape, then it shows the “true” measurement.
Yes.
It’s a bug in the Dimensions Include Stroke Weight setting.
We always have that shut off when creating cut paths. We need a filled shape for that. No stroke.
If you turn it back on (checked) the dimensions show true.
Can you check if that is true for you?
I’m finding it hard to believe this isn’t a new thing, but then most cut paths we do are rectangle, rounded rectangle, or ported from illustrator for die cutting.
