HOW TO MAKE POINT CONECTION ALWAYS PERPENDICULAR TO THE PLANE WHEN CHANGING ANGLE ?

[traiduong014969]

Hi all,

I am beginning to create basic shapes with script . So when I create the elbow. It's has some problem appear with point connection. With A1=90 degrees. It's fine, however when I edit with A1=45 degrees. The point connection incorrect as show (point connection not perpendicular with elbow). I want to make a elbow with angle parameter. But I only create them when its has 90 degrees. Someone know this problem, please  explain for me. Thank you for your support !

This is my code:

import aqa.math
import math
from varmain.primitiv import *
from varmain.var_basic import *
from varmain.custom import *

@Anonymous(Group="Elbow", TooltipShort="Elbow Insulation", TooltipLong="Insulation Elbow", Ports="2", LengthUnit="mm")
@group("MainDimensions")
@Anonymous(D1=LENGTH, TooltipShort="Radius of Elbow")
@Anonymous(R1=LENGTH, TooltipShort="Bend Radius")
@Anonymous(A1=ANGLE, TooltipShort="Bend Angle")
@Anonymous(S1=LENGTH, TooltipShort="Number of Segments")
@group(Name="meaningless enum")
@enum(1, "align X")
@enum(2, "align Y")
@enum(3, "align Z")

def Insulation_Elbow (s, D1 = 120.0, R1 = 152.0, A1 = 90.0, S1=4, ID = 'Insulation_Elbow', **kw):
o1 = ARC3DS(s, D=D1, R=R1 , A=A1, S=S1 )

s.setPoint((cos(A1)*R1, 0, 0), (cos(A1), 0, 0))
s.setPoint((0, cos(A1)*R1, 0), (0, cos(A1), 0))

I recommend using an existing elbow script (see attached zip file) and making changes to it. This will also allow you to see how the elbows are scripted and help with your coding.

@traiduong014969 please use the formula in give sanpshot. then use B & C value in setpoint as per geometry.

Thank for your reply. 

I have converted the formular follow your guide to R value

Adeg=asRadiants(A1)
Bdeg=asRadiants(A2)
A2=180-(A1/2)
C=R1*sin(Adeg)/sin(Bdeg) ---> R1= C*sin(Bdeg)/sin(Adeg)
B=R1*2*sin(Adeg)-----> R1= B/(2*sin(Adeg))

so i get  the value as show:

s.setPoint((C*sin(Bdeg)/sin(Adeg), 0, 0), (1, 0, 0))
s.setPoint((0, B/(2*sin(Adeg)), 0), (0, 1, 0))

And i use command ''PLANTREGISTERCUSTOMSCRIPTS'' . It's ok but with command ''(TESTACPSCRIPT "Insulation_Elbow")'' . It's appear an error

I don't know i have convert setpoint value is correct or incorrect?

Please help me !

@traiduong014969 use the formula as it as. And use below setpoint.

s.setPoint((C, 0, 0), (1, 0, 0))
s.setPoint((0, B, 0), (0, 1, 0))

Yes, I have just tested code with setpoint that you guide. However I still see this an error as snaphot. I think that have a error what i have not found yet

This is my code:

Adeg=asRadiants(A1)
Bdeg=asRadiants(A2)
A2=180-(A1/2)
C=R1*sin(Adeg)/sin(Bdeg)
B=R1*2*sin(Adeg)

s.setPoint((C, 0, 0), (1, 0, 0))
s.setPoint((0, B, 0), (0, 1, 0))
