Get distance between midpoint of face and edge

Lee_Hesketh

Hi there. How would I get the distance between the midpoint of a selected face and an adjacent edge?

@LeeH, Kindly refer below video and image which will be helpful to you. X=Red, Y=Green, Z=Blue show color coding for measurement lines as shown in below video and image.



Distance from hole center will be given in all X, Y and Z directions when hole and edge point is selected as below.



When the mouse cursor is moved on the area highlighted in red box, it will show the dimensions from hole center.

@viru Sorry for not explaining properly, I meant to be able to get that distance using feature script.

Here's an example that does this, assuming a few things:
1. "Midpoint of a face" means the midpoint of the parameter bounding box (as opposed to, say, the center of mass or center of world-space bounding box, both of which might not be on the face, or the point on the face farthest from an edge, which is not very easy to compute)
2. "Distance" means Euclidean "as-a-bird-flies" distance as opposed to geodesic "as-an-ant-crawls" distance.
3. You want the distance to the closest edge, rather than a specific one.

When the face is a rectangle, assumptions 1 and 2 don't matter.

@ilya_baran Thank you very much for the example. It's greatly appreciated. How could I modify it so that it finds the other edge, not the closest?

You can specify the edge in evDistance with a query -- for instance, you could iterate over the adjacent faces and call evDistance on each one.
