Detailed Playhouse CAD Design

I have a hand-drawn sketch that captures the overall size and basic shape of a children’s plywood playhouse. From that starting point I now need a fully-defined 3D CAD model that a carpenter—or even a CNC shop—could trust.

Scope
• Turn my sketch into a clean 3D model.
• Add complete dimensions for every face, opening, and joint.
• Specify each plywood panel’s length and width, all at 18 mm (¾ in) thickness.

Because the sketch only shows the outer envelope, we’ll refine door, window, roof pitch, and floor details together during the modelling stage. I’m comfortable reviewing screenshots or quick viewer files as we iterate.

Deliverables
1. Native CAD file (SolidWorks, Fusion 360, SketchUp, or similar) plus standard exports (.DWG/.DXF and PDF).
2. Dimensioned drawings for walls, roof, floor, and trim.
3. A simple panel schedule listing every plywood piece with its finished size.

Accuracy of dimensions, consistent 18 mm wall thickness, and tidy layer/part naming will be my acceptance checklist.

If this sounds straightforward for you, let’s get building—on screen first, then in the workshop.
