Refinery package Packing.PackRectangles - items are outside the containers

Packages
1

Hi,

I am wondering if someone has encountered a similar problem.

I am using Packing.PackRectangles node of the Refinery package to pack rectangles in 3 containers as shown below:

D_11.11_test2_2022-11-13_06-41-43
D_11.11_test2_2022-11-13_06-41-431220×820 82.4 KB

I have a list of rectangles as rooms and they were packed in containers. It works well for the second container, however, rectangles from the first and third containers are outside the perimeter:

D_11.11_test2_2022-11-13_06-42-03
D_11.11_test2_2022-11-13_06-42-031220×820 81.2 KB

I cannot find the logic of why it’s happening.

I found a discussion about this topic:

The solution was to translate rectangles. I think it is not my case, but maybe I am wrong.

Do you have any suggestions on what I should adjust?

Many thanks!!!

Where’s your code?

If I recall (not done it for a while) you have to get the translations right for your visualisations or it messes up.

Hi Alien,

here is my code:

Tomorrow I will try to do some translation…we will see:)

Many thanks!

The bin packing nodes in the refinery toolkit require the container be oriented and located in a particular fashion. Try rebuilding your containers at the origin with no rotation, and translate the rooms after placement.

Hi Jacob,

I followed your instruction and it works:) Thank you!
From my initial containers (rectangles created from points), I got dimensions and created new rectangles, which I translated to the centre point of my initial containers.

Thanks and have a nice day!
