Hi Dr. Sassi,

thank you very much for your valuable tips and the wonderful explanation of the polygon alignment and the resulting effect of the Phong.

We will start another series of tests to determine the optimum number of cuts for different tent sizes. We test how close the cuts should be so that the roof surface appears line-free due to the Phong and yet the edge between the roof segments looks smooth and not angular. We will also look at the roof peak and the transition to the vertical to see how many cuts are actually necessary. The tip on the verticals will help to keep an better overview of the parallels.

We hope to find a good solution. Best regards.

Hi Dr. Sassi,
Thank you for your reply.
For a first contact we wanted to make sure that we describe the problem correctly and that there are no errors in the problem description due to a translation.
Your example file reflects the issue very well. The reduction of the stripes in the example is impressive. It seems to be a combination of the position of the cuts and the phong. We have already tried the phong, but it does not change the appearance.
We can provide a file. There are three steps included to show the beginning of the project, an intermediate step and the result.

We are grateful for any helpful tips.
Kind regards.
