## Evaluate Geometry

## Evaluate Geometry

(OP)

I am using SW2016. I created a "T" section in Sketch. I selected "Evaluate" to determine the section properties (Ixx, Iyy, centroid, etc). Some of the MOI show a small number but should be "0". One of the results, "Angle between principal axes and sketch axes" shows a none zero number. I guess it's the difference between X and Ix, Y and Iy? How do I get this angle to show 0.00 degrees?

Thanks,

Thanks,

Add some constraints to the sketch?

I.e., horiz/vert lines parallel to axes?

Sometimes you can sort of see what's going on, during a redraw operation.

SW starts anew with every object oriented at random, and positions and repositions the objects until they satisfy all of the constraints you have applied.

It can sometimes be interesting to remove a few constraints at random and observe how SW destructs and rebuilds what you have constructed.
