Hi, V5

Hi Steve GCon , If the curves are not actually joined, normal selection ; if joined , use Ctrl-Shift sub-object selection.

Hi,
not joined,

I get ‘curves are G1’

says thats tangent line to curve, am I right ?

Cheers

To within the angle tolerance of the file, yes, however the actual number of degrees is also printed in that GCon report on the command line.

Hi,
V5
.perhaps in a later version, as no degrees gets reported on my command line.

This is what I see in V5:

Curve end difference = 0.000 millimeters
The radius of curvature difference cannot be calculated.
Tangent difference in degrees = 0.000
Curves are G1.
