A 3d sketch app with huge potential!! However, I don’t quite used to draw the base frame every single time. Maybe can add a toggle to set the viewport plane as the base frame(skip the drawing frame step) and use a slider or wheel to control plane depth. And should take the Apple Pencil double tap function as a customizable shortcut, e.g., switch pen shape or draw frame mode. Additionally, the fill mode is necessary! Too exhausting to fill a block.🥲
