How to link an aluminum window design to quantities and the cutting list

Short answer

When the window design and the quantities live apart, every change means recalculating the cutting list by hand and risking an error on the shop floor. Linking them means the design drives the numbers: change a dimension or a profile, and the profile lengths, the glass area, the accessories, and the cutting list all update together. The quote and the workshop work from one source instead of two copies that drift apart.

Key takeaways
  • Separate design and quantities force manual recalculation on every change.
  • Linking them lets the design drive the lengths, glass, accessories, and cutting list.
  • The quote and the workshop then read from one source, not two drifting copies.
  • An accurate cutting list reduces waste and remakes on the floor.

What breaks when design and quantities are separate?

  • A dimension changes in the drawing but the quantity sheet is not updated
  • The cutting list is recalculated by hand and picks up an error
  • The quote uses one set of numbers and the workshop uses another
  • Waste rises because offcuts are estimated instead of computed

What does linking them actually mean?

The design becomes the single input. The system reads the system type, the dimensions, and the profile, and derives the quantities from them. There is no second sheet to keep in sync, because the numbers are computed from the design every time it changes. Update the drawing and everything downstream follows.

What flows automatically from the design?

  • The profile lengths for each member
  • The cutting list with a waste factor
  • The glass area per unit
  • The accessories and gaskets per leaf
  • The aluminum weight used for pricing

Why does the workshop benefit too?

The floor cuts from a list that matches the approved design exactly, so there is less guessing and fewer remakes. When a waste factor is built into the list, material is ordered closer to what the job actually needs. The same design that produced the quote produces the cutting instructions, which keeps what you priced and what you build in agreement.

Frequently asked questions

Does this replace our design software?

No. It works from your design and turns it into quantities and a cutting list. The goal is to connect the design to the numbers, not to redraw the window.

Can it produce a cutting list for the workshop?

Yes. The cutting list is derived from the design with a waste factor, so the floor cuts from the same source the quote was built on.

How is waste and offcuts handled?

A waste factor is included in the cutting list and the cost, so both the material order and the price reflect real offcuts instead of a rough guess.
