Here's the drawing: a one-piece, bend-formed sheet metal enclosure.
This is an alloy steel sheet metal part — drawing number EXERCISE 154 — programmed in SolidCAM Pro. Material thickness is 2.5 mm and the finished part weighs 0.2 kg, with developed area and volume listed in the part parameters.
Seven views in total define the geometry: the flat pattern, multiple orthographic projections, a section view, and a 3D isometric. The flat pattern calls out 14 bend lines and comes with a matching bend table — 14 bends at 90°, a uniform 1 mm inside radius, K-factor 0.44, and up-form/down-form direction flagged for each line. Nothing is left for the shop floor to interpret; the drawing is ready to run as issued.

This is a single-piece, bend-formed U-shaped housing for mounting equipment. There is no welding anywhere on the part — structural rigidity comes from the bends themselves.
1. Clear functional zones.
One end is the fan mount, which carries the cooling fan. The opposite side wall is pierced with groups of elongated ventilation slots, so the fan and the louvers form a complete airflow path through the enclosure — exactly what a heat-generating electronic assembly needs.
2. Mounting and assembly.
The base plate carries both mounting holes and slotted locating features. That means the part works two ways: it can hold internal components in place, and it can be bolted as an assembly into a rack or onto a host machine. Notches and cutouts along the edges are there for cable routing and to clear adjacent hardware during assembly.
3. Material choice.
Alloy steel gives higher strength than mild steel, with better vibration resistance and load-bearing capability. It's a sensible fit for protective housings on small industrial control modules and electronic equipment.
