Define the measurement
Decide whether the starting quantity is an area, length, count or another input. Write down the unit so everyone knows what the assembly expects.
Make your PlanSwift
assemblies work harder.
Build a reusable estimating approach around your materials, labour and pricing assumptions. We help you review existing assemblies or plan a more consistent starting point.
Useful assemblies start with clear inputs.
Separate the assumptions
Make height, coverage, spacing and waste assumptions explicit. Keep purchasing units separate from measured units when they differ.
Test a small example
Check a known quantity manually, then compare the result with the assembly. Try a different size or configuration before reusing it on live work.
Example: a wall is more than a length.
A wall assembly may need height, number of faces, sheet size, openings, waste and a labour allowance. Those decisions depend on the work you price. A useful template makes the assumptions visible instead of burying them in an unexplained total.
A few useful answers.
What is the difference between a part and an assembly?
In PlanSwift, an assembly groups parts so they can be applied together. How you organise them should reflect the way you measure and price the work.
Can you review assemblies we already use?
Yes. Bring an example, its intended inputs and a result you want to check. We can discuss the review and any changes required.
Will a template remove the need to check an estimate?
No. Rates, scope, drawing revisions and project conditions still need review. A reusable setup helps make the process more consistent.
