Hi,

I have a question regarding sum the coordinates of 2 lists parts.

Exercise:

The are 2 lists:

List A: Represent the start coordinates of 3 line elements

List B; Represents the offset (delta) distance from the start coordinate.

Wanted result:

Geometry 1: {0;0} - **Triangle:**

start point; 40.8, 0, 5.3

2nd point; 40.8, 7,8, 5.3

3rd point; 38, 7.8, 5.3

Geometry 2: {0;1} - **Triangle:**

start point; 40.8, 0, 11.6

2nd point; 40.8, 7.8, 11.6

3rd point; 38, 7.8, 11.6

Geometry 3: {1;0} - **Rectangle:**

start point; 52.8, 0, 5.3

2nd point; 53.6, 0, 5.3

3rd point; 53.6, 4.2, 5.3

3rd point; 52.8, 4.2, 5.3

However, when I try to do this, the Addition commands adds the delta distance of the rectangle already to the start point of the second triangle. Resulting in 2 Rectangles and 1 triangle.

Triangle 1 = ok

Rectange --> should be triangle --> false

Rectangle 2 = ok

any one a suggestion? it can probably be done with a list manipulation, however i cant see it at the moment.

Thank you in advance. 2020-03-28 combine lists to 2 triangles and 1 rectangle.gh (9.4 KB)
