Plugin needed: calculate countour length

[liquid98]

Hi,

I'm looking for a sketchup plug-in to calculate the contour length of a 2D plane, like for instance this:

must be easy, but I couldn't find a plugin myself.

Any help would be appreciated.

You don't need a plugin for that. See attached.

Hi Gaieus,

Thank you very much for the quick help! So I just select the lines en not the plane, and than read the data
from the entity info. Great !

Good luck!

Yes, just the bounding edges. The double click > extract from selection second click is only needed when your bounding edges are not one, continuous polyline (but exploded for instance).

Cautionary Comment
In some cases the info you get from the entity info is a theoretical length and not " segment length". For example draw an arc at a given radius, measure the angle and check the entity info and the answer one gets is d= r X theta ( theta in radians). Explode the curve and the entity info will now give you the sum of the segment lengths. I don't know how many tools do this.

I expect only circle and arc segments.
