yeah I read all that stuff but I really struggle with drawing primitive forms from different angles

I can do like the 2 point perspective training routine where you draw 2 VPs and you draw boxes by connecting all the lines

but how the fuck do you draw like a rotated crooked pyramid floating through space attached to a slightly askew box and have it all match perspective?

I just have no idea how to draw 3d shapes properly.
