If this template helps then use it. If not then just delete and start from scratch.

I am aiming to use an excel spreadsheet to adjust the orientation of a polygon triangle from left to right (orientation 270 or 90 degrees). To do this on multiple trials I will use a spreadsheet but I don’t know how to input this information into the spreadsheet so that the trial loop will read it to change the orientation of the polygon?

Mnay thanks,

Seline

Hello Seline,

add a column, for instance ori, to your Excel-file

and refer to the column by its name in the polygon-properties-layout tab. Don’t forget to set it to set every repeat.

In the example the orientation of the triangle will change to up, right, down, and left.
