How to measure an area of a irregular shape?

[[Ma...]]

Good morning everyone,
I need to measure the area of an irregular shape. I created a section, then defined two points and drew a line between them. Now I need to measure the area between them. Is it possible?

I'd measure the two radii and the large OD. Using the tangent function with the large OD and the two radii, create the two intersection points (not sure how you did).

Create a local alignment from the left radius as ZX origin. For planar (X+) use the Right radius. Then us caliper or simple distance. Intersection to intersection.

Lo siento Marco. I thought I was in the Calypso forum. I'm not familiar with this software.

Hi Marco,

you can check a section directly for area. If it's not closed, the ends will be connected by a line in the background for the area calculation. So you could either create the section only for the marked area, or you create another Section -> Other -> Section from points. The selection for the section from points could be inside sphere with the center point of the sphere being the symmetry point from Point 1 and Point 2 for example.

Hi Nanno!

First of all thank you! 

Ok, with some trick I made what I want, but I think the area it's not good. Look at the image.

It will display a negative value because the vectors of the section are directed from outer side to the inside. Or is the absolute value not plausible? You could check by Operations -> Sections -> Close Gap manually and check the resulting closed section.

This is the window with parameter I used: could it be that the direction of the normals are wrong? Because in the window the nominal value is 0.00. Could it be that if the nominal value, due to the wrong directions of the normals, is negative it display 0.00?

I don't know why the image doesn't display. I attach it here.

The image is displayed for me. 

The greyed out value seems to happen in the check dialog, if the gap is quite large. After OK, the nominal value is calculated though as seen in the label. 
The negative sign is displayed because it's an enclosed area like an inner diameter compared to an outer diameter for example. Same would happen with volume checks.
