Solved: Trouble with Slope and Delta Y in Subassembly composer

lunhatduy92 · ‎07-15-2018

I have a trouble with Slope and Delta Y in Subassembly composer. Please see the pictures below:

I want to the Delta Y from P3 to P10 = 6, so I use 6-(P4.Y-P3.Y). But when I import to Civil it was not 6. It is 5.8343. Perhaps I used wrong API. Have anybody could show it for me. Thank you so much!

I also attack my pkt file below.

It seems to be measuring as 6 for me in Civil 3D so I don't know what the issue is but as a few general changes...

The surface will (most likely) never be flat and therefore your decision on testing the depth to P3 should not test against AP1 which is on the surface at the origin. I would recommend changing the AP1.DistanceTo("P3")>6 to math.abs(P3.DistanceToSurface(EG))>6
Similarly I would change AP1.DistanceTo("P13")>12 to math.abs(P13.DistanceToSurface(EG))>6
I'm not sure why the ylength on from P3 to P10 isn't working out as 6 as wanted but for P10 you could change it to DeltaY=6-L3.ylength to see if that corrects it for you

You can try using the expression 6-(math.abs(P4.Y)+math.abs(P3.Y)) for "Delta Y"

Great! It worked. Thanks both of you.

especially thanks for your recommend changing. ^_^
