Why Engineers Use AutoCAD Total Area LISP
Instead of explaining AutoLISP, explain the problem.
Every engineering discipline relies on area calculations during design, estimation, and project verification.
While AutoCAD’s built-in AREA command works well for measuring individual objects, it becomes repetitive when working with dozens or even hundreds of rooms, slabs, or floor finishes.
The BuildMEP Total Area AutoCAD LISP eliminates this repetitive work by calculating the combined area of multiple selected objects in one operation.
Instead of measuring each object individually, you simply:
- Select the required objects.
- Press Enter.
- Get the total area instantly.
This saves time, reduces manual calculation errors, and improves productivity on projects of any size.
Common Engineering Applications
This is where BuildMEP becomes different.
Use icon cards or boxes.
🏢 HVAC Engineering

Quickly measure:
- Room areas
- Apartment layouts
- Gross Floor Area (GFA)
- Net Floor Area (NFA)
📐 Quantity Surveying
Perfect for:
- Tile quantities
- Waterproofing
- Floor finishes
- Concrete slabs
- Roofing
- Landscaping
🛋 Interior Design
Calculate:
- Carpet
- Vinyl
- Raised flooring
- Ceiling finishes
🚧 Civil Engineering
Measure:
- Parking areas
- Pavements
- Hardscape
- Softscape
- Site development areas
Why This Tool Saves Time
Imagine measuring the floor area of 120 rooms.
Using AutoCAD’s AREA command:
- Measure Room 1
- Record the value
- Repeat 120 times
- Add everything manually
Now imagine using the Total Area LISP.
- Run one command.
- Select every room.
- Press Enter.
- Done.
For large projects, this simple automation can save hours over the course of a project.
💡 BuildMEP Engineering Tip
Before calculating the total area, make sure your room boundaries are fully closed and your drawing units are correct. Clean drawings produce reliable results and prevent incorrect measurements.
