EZ Fireproofing

Structural framing and columns are included; an extra category can be added. Restrict the first run to a small, inspectable set.

Model / link

Select the host or loaded linked model containing the steel. Check that its geometry workflow and placement match the chosen source.

Steel workset filter / Level

Choose a workset and level to narrow steel in the selected source model, or the unrestricted choice. These filters do not assign the generated fireproofing to a workset. They are ignored while an explicit element selection is active.

Additional category

Adds the selected category alongside structural framing and columns. Use when qualifying steel is modeled in another category; verify the selected category contains the intended geometry.

Only elements visible in the active view

Restricts candidates using the active view. Confirm the view’s crop, visibility and filters before running so hidden members are not unexpectedly omitted.

Select Elements… / Clear Selection

Select Elements captures native or linked steel from the chosen model and allowed categories. While that selection is active, steel workset, level and active-view filters are ignored and disabled. Clear Selection restores those filters. Esc during picking keeps the previous scope. Read the candidate count before confirming the run.

Thickness fields use the dialog’s selected units, not automatically the project units. Changing in/mm converts the default and rule values.

Fireproofing workset

Choose Use active workset, an existing host user workset, or Create new workset…. This destination belongs to the host model even when the steel is linked. The selector is disabled when the host is not workshared. An existing destination is remembered; pending new-workset creation is not saved.

New workset name

Shown after Create new workset…. Enter a non-empty, unique host workset name without Revit-prohibited characters. The workset is created when modeling runs, in the same Undo transaction as its fireproofing. Canceling the run rolls it back; a run that creates no protection does not leave an empty new workset. Check for Changes retains each existing shape’s actual workset, including manual reassignment.

Fire rating

Choose 1 hr, 2 hr, 3 hr or 4 hr. The value selects matching rules and is recorded on each generated shape; use the rating required by the project specification.

Default thickness / Units

Positive numeric fallback for members with no matching rule; initially 2 in. Units can be in or mm. Check the displayed values after converting and before modeling.

Profile · Contour (spray) / Box (board)

Contour follows the steel section for a spray-style envelope. Box produces a board-style enclosure. Profile changes both occupied space and resulting quantities.

Revit geometry / IFC geometry

Revit mode uses member end faces and suits native steel. IFC mode handles fabrication geometry with copes or split solids, including IFC/Tekla exports. It reads the existing geometry; it does not import or convert a model.

Steel material keyword

Native geometry uses the entered material keyword; recognized STEEL, ASTM, A36, A53, A500, A913 and A992 names also count. IFC links skip the material check. An overly narrow keyword can omit native steel.

Skip top flange of level beams (under deck)

Omits top-flange coverage on level beams beneath a deck. It is a specific geometry option, not a general instruction to omit the top surface of every steel member.

Replace fireproofing created by an earlier run

Replaces previous tool-generated protection for processed members. Use after changing profile or thickness; leave off only when your intended workflow does not replace existing generated shapes.

The first matching rule wins. Put specific section rules above general rules. Rules with non-positive thickness are not used; provide a valid positive default.

Rule · Rating / Applies to

Rating matches the chosen fire rating, or Any for all ratings. Applies to limits the rule to Any, Beams or Columns. Both conditions must match before evaluating the section pattern.

Rule · Section pattern

Matches member type names with * and ? wildcards. Several patterns may be separated by semicolons or commas; blank matches all sections. Example: W12*; W14* for an applicable beam rule.

Rule · Thickness

Positive thickness in the displayed in/mm units. The header changes with Units. It overrides Default thickness when the rule matches.

Add Rule / Remove Rule / Move Up

Add inserts a rule using the current rating and default thickness. Remove deletes the selected rule. Move Up gives the selected rule earlier priority; repeat until specific rules precede broad matches.

Settings and rules are retained when the dialog closes. Recheck them before processing a different model.

Model fireproofing

Validates thickness, collects candidate steel and asks you to confirm source, candidate count, rating and rules. It creates protection and reports covered area/volume, rule matches, skips and failures. Operation cancellation rolls back: the dialog reports that nothing changed.

Check for Changes

Finds generated protection whose source steel was edited, moved or deleted and reconciles it. Use after a structural model revision rather than assuming old protection moved with its source.

Export Quantities

Writes an Excel workbook with area, volume and board feet per member and level. Choose a destination and inspect the workbook units and member totals before using the quantities.
