Array with python for double component

[traiduong014969]

Hi guy,

Recenly, Im trying create a plastic flange. In this have two componet I need make with array feature.

This is number 1 and 2. You can see snapshot below. Howerver, both number 1 and 2 in the same place or  created  unequal angle

Here is piecs of code to make them. Somone can help me fix that.

Thank you !

 phi1=360/N

    FirstAngle1= phi1/2

    InAngle1= FirstAngle1

    phi2=360/N

    FirstAngle2= phi2/4

    InAngle2= FirstAngle2

    No = 0  

    while (No<N😞

        number1 =  CYLINDER(s, R=D2/2, H=T, O=0.0).rotateY(90).translate((0,D1/2,0)).rotateX(InAngle1)

        number2 =  CYLINDER(s, R=D2/2, H=T, O=0.0).rotateY(90).translate((0,D1/2,0)).rotateX(InAngle2)

        InAngle= InAngle+ phi

        InAngle2= InAngle2+ phi2

        No= No+1

It looks like your FirstAngle1 = 36, but should be 90 - 36 = 54
Keep playing with the FirstAngles until you get them in the correct start position.

Thank for your answer. I have just test with your formular. Howerver,  it seems the angle dont follow any rules. You can see snapshot that i test with N=3, N=5,  N=6

Your cylinders look correct, change the brace FirstAngle to 90
