1. Coordinate system & orientation

Use a right-handed Cartesian coordinate system

Origin (0,0,0) at the geometric center of the frame

X axis: horizontal (left negative, right positive)

Y axis: vertical (bottom negative, top positive)

Z axis: depth (rear negative, front positive)

2. Overall frame geometry

Frame type: rectangular plate with through-cut openings

Orientation: landscape

Outer dimensions:

Width (X): 480 mm

Height (Y): 380 mm

Thickness (Z): 10 mm

Frame lies centered about origin

3. Inner usable aperture

Inner clearance rectangle centered within outer frame

Dimensions:

Width: 460 mm

Height: 360 mm

Results in uniform frame border of 10 mm on all sides

Inner aperture is a through-cut (full Z depth)

4. Small photo cut-outs (left block)
Quantity & arrangement

Total: 12

Grid arrangement:

3 rows (Y direction)

4 columns (X direction)

All small cut-outs:

Identical size

Portrait orientation

Rectangular

Through-cut fully through Z

Individual cut-out size

Width (X): 48 mm

Height

Absolutely — this is a smart move. Below is a **clean, precise, math-first specification** of your design, written so it can be fed directly into **another AI, CAD system, or parametric engine** without ambiguity or “interpretation”.

I’ll avoid OpenSCAD syntax entirely and describe this as **pure geometry + constraints**.

# 📐 Mathematical / Geometric Specification

**Parametric Photo Frame Layout**

## 1. Global coordinate system

* Use a **Cartesian coordinate system**
* Origin **(0, 0, 0)** at the **centre of the frame**
* X-axis: left (−) → right (+)
* Y-axis: bottom (−) → top (+)
* Z-axis: back (−) → front (+)

All dimensions in **millimetres (mm)**.

## 2. Overall frame geometry

### Outer boundary

* Rectangle:

* Width: **480**
* Height: **380**
* Thickness (Z): **10**
* Extents:

* X: −240 to +240
* Y: −190 to +190
* Z: −5 to +5

### Inner opening (frame hollow)

* Uniform border thickness: **10**
* Inner rectangle:

* Width: **460**
* Height: **360**
* Extents:
