Knowledge-based engineering, self-serve
A belt conveyor that builds itself
Set the belt width, the length and the height and the whole machine follows: the frame, the legs and braces, the drums on their bearings, the return rollers on their shafts and brackets, the belt as a closed loop — every part exists because a rule says it must, and the parts list and the price are the same model read a different way.
Stretch it
Drag Length. Cross bars and return rollers are counted from it — each roller brings its shaft and its pair of drop brackets with it — and the belt loop, the slider sheet and the rails re-size in the data and in 3D.
Widen it, raise it
Belt width sets the frame width, the drum and shaft lengths, the roller lengths and the brace lengths; height sets the legs. One input, a dozen dependent dimensions.
Built the way it is built
Nothing rotates in mid-air: drums run on stub shafts in flange bearings outside the rails; return rollers turn on fixed shafts held by brackets under the rails. Every one of them is a part in the list.
Read the parts list and the price
The Parts List page gives every profile by length, every shaft, bearing and bracket by count, the belt by area; the Price page turns them into money at your rates. Change the length and both pages follow.

How this works
This is not a 3D file with sliders. The product model owns the facts (belt width, length, height, which side the motor sits); quantity rules mint the parts from them (cross bars and return rollers counted from the length, brackets two per roller, legs and feet four); map rules derive the geometry as a view of the product — when a rule adds a roller, its cylinder, its shaft and its brackets appear where the rail is; and the parts list and the price read the same relations. This one was built by our build service from a photo and a two-paragraph spec; the same engine powers plain calculators, instant-quote widgets, and full configurators.
