get these positions on scene view gui ?!!!

how i can get these positions on scene view gui to draw my buttons or labels there ?
and an important note, when user would change the size of scene view, these buttons have to keep their positions.
image is attached.
thanks.

This sort of thing is best handled through proper use of anchoring and scaling in your UI.

Here are some notes on UI Anchoring, Scaling, CanvasScaler, etc:

its about editor scripting gui

Oh, check out how good old ProBuilder does it… they anchor buttons at the top center, and their ProGrids tool anchors stuff in the upper left. It’s all downloadable source code from the Package Mangler.

thanks i’ll try it
