Не могу изменить размер строки, вероятно, в пределах сетки xaml

Question

Я пытаюсь выучить xaml с помощью c #, я хочу сделать 2d модель, похожую на 3d.

Я новичок на сайте и только начал играть с xaml, так что потерпите меня, если я допустил ошибки в том, как я представляю проблему.

Сначала я попытался сделать это без компоновки сетки, но не смог заставить его работать, поэтому я сделал это с сетками в сетках, может быть, я ошибаюсь.
