Utility pole and angles I am using the following MOC from the Internet:

This model is fine if the sets of power lines are all in a straight row. But what about at an angle? How does the model need to be adjusted if the lines meet at, for instance, a 90 degree angle? 45 degrees? Thanks.
The pole itself can be rotated on almost every level, so that’s nothing you need to worry about.

Additionally, you may want your cables to be parallel. To achieve this, you need to increase the width of your bars, or more specifically, the distance between the cable supporters.
If your distance between the supporters for a straight line is d and you want an angle of θ, you need a distance of d/cos(θ/2) at the angle, which can be obtained using trigonometry:



So, for an angle of θ=45°, you need to increase your distance by a factor of 1.08. For θ=90°, it’s a factor of √2 = 1.41.

The obvious items to adjust the distance are 1×1 round bricks and plates. Also, you obviously can only approximate the perfect distance with bricks in most cases, but the inaccuracy will be negligible.
