How to measure the total outside perimeter length of a sheetmetal flat-pattern?

[bradlawrence]

As you can see below, got a simple sheetmetal flat-pattern. I want to measure the total outside perimeter length of the flat-pattern without holding the crtl key and selecting each outside edge. Looking for some kind of loop command.

Does anyone know how to accomplish this? Any assistance would help.

You can select the surface per below and it will tell you the total perimeter of that bend surface, but that is not what I am looking for.

I can think of a couple ways, probably lots more.

Option 1:

a. Copy and paste the top surfaces into one quilt (probably 3 surfaces on your example - 2 flats and the unbent round)

b. Select one edge of the copy

c. Hold SHIFT and hover over of the copy and you should get the "boundary" edge

d. With the edge selected, do a Measure, Length

Option 2:

If you have more surfaces and it is a pain to copy-paste them into a quilt

a. Create a cross section somewhere in the middle of the part

b. Create a curve from cross section

c. Select the outer (perimeter) portion of the curve

d. With the edge selected, do a Measure, Length

Use a seed and bound to select the sheared surface, then find the area and divide by the thickness. I can't supply detailed instructions, but that process should work.

I added an explanation of a quick method to do this at the link above.
