Creates an assembly from all currently visible entities. Isolate a structure or area first using the Takeoff tab's visibility controls, then click From Visible to capture exactly what's on screen.

From Selection

Creates an assembly from entities you've selected (checked) in the Takeoff tab. Select the rows you want, switch to Assemblies, and click From Selection.

Once created, the assembly shows a category breakdown with colored chips and counts, plus a visual bar showing the proportion of each category.

Interface Assembly tabs

Each assembly card has four tabs:

Breakdown

Category breakdown showing which trades are represented and their entity counts.

Parts

Custom parts list. Some entities with measurable geometry can auto-generate SF and LF data — but the manual measurement tools are the most reliable source.

Beam Inv

Beam inventory — Auto Beam analyzes each object's bounding box cross-section to determine its size, then generates a list with section, name, quantity, length, and board feet.

Auto

Auto tools including Auto Tag — creates sequential tags for each item in the assembly and generates a numbered reference list.

Feature Beam inventory

The Beam Inv tab is the standout feature. FF analyzes each object's bounding box to find the cross-section dimensions, determines the nominal size (e.g., 3.5x7.5" = 4x8 beam), and groups identical sections together.

The result is a complete beam inventory showing section size, name, quantity, total length, and board feet for each group. Expand any row to see individual members with their exact lengths.

Beam inventory for BBQ structure — 103 parts with sections, quantities, lengths, and board feet

This BBQ structure has 103 parts across multiple beam sizes — 28 rafters at 3.5x7.5" (755 BF), 8 beams at 2.0x13.5" (626 BF), 16 purlins at 7.5x7.5" (1,291 BF), and more.

Clicking the expand arrow on any row drills into the individual members with exact lengths and piece counts:

Here, 465 LVL Rafters at 1.7x11.9" are broken down by length — 132 pieces at 13'-9", 44 at 13'-3", and so on — totaling 5,020 linear feet and 8,437 board feet.

Actions Assembly controls

Add Selected

Add more entities to the assembly from the current selection

Export

Export the object list and beam inventory as CSV

Rename

Change the assembly name

Notes

Add notes to the assembly

Zone

Assign a zone label for organization

Delete

Remove the assembly

Each row in the beam inventory also has visibility controls — eye toggle to show/hide that beam group in the model and isolate to see only that group. This lets you visually verify what's in each section size.

Note: Some entities can auto-generate SF and LF data based on their geometry, but the manual measurement tools are the most reliable source for area and linear quantities. Use beam inventory for structural members and manual tools for everything else.

Summary: Create assemblies from visible objects or selections. Use Beam Inv for automatic structural member inventories with sections, lengths, and board feet. Use Auto Tag for sequential numbering. Export everything as CSV.
