Geometry error to debug
 
Hi, i am desperately debugging on this, hope there is someone could advise.

After running the satellite, I have an error message like this "No line link to point PA and PAB1", also "No line link to point PAB2 and PB".

My geometry command in Q1 file is like this:

GSET(V, CV01, PA, PAB1, PAB2, PB) GSET(L, L01, PA, PB, 1, 1.0, CRV, CV01) GSET(F, F01, PA, PAB1.PAB2, PB,-, PC,-, PD,-)

For your information, all variables are declared and assigned values, all points are defined. PA and and PB are the start point and ending point of the curve named cv01 respectively. PAB1 and PAB2 are intermediate points on this curve.

Thank you for your time.

FYI, those command are in different lines.

Jas,

As far as I recall, defining the curve CV01 as

GSET(V, CV01, PA, PAB1, PAB2, PB)

and the line L01 on it

GSET(L, L01, PA, PB, 1, 1.0, CRV, CV01)

only uses the intermediate points, PAB1, PAB2, but there is no line connecting PA to PAB1 and PAB2 to PB. Rather, there is a line connecting Pa to PB, passing through PAB1 and PAB2. This is what Satellite is complaining about.

You should therefore merely change the frame definition from your current one, i.e.,

GSET(F, F01, PA, PAB1.PAB2, PB,-, PC,-, PD,-)

to

GSET(F, F01, PA, - , PB,-, PC,-, PD,-)

I hope this would remove the difficulty.

Thank you, it is solved.
