Memory Tools

Work with selection sets like a calculator's memory. Stored selections are project-specific and persist between Revit sessions. Use memory tools to build up complex selections incrementally, carry selections between views, or save a working set for repeated use.

Tool	Action
MWrite	Overwrite memory with the current selection
MAppend	Add selected elements to the existing memory without replacing it
MDeduct	Remove selected elements from memory
MRead	Recall the stored selection -- elements are selected in the active view
MClear	Reset stored selection to empty
Next / Prev	Step through stored elements one at a time, zooming to each
Copy State / Paste State	Copy the current view's Visibility/Graphics state and paste it to another view
Save Memory as Selection	Promote the memory contents to a permanent Revit Selection Filter

Add to Memory

Adds the current selection to project memory without replacing what is already stored. Use it when building a complex selection set incrementally across different views. Select elements, then run Add to Memory (Ctrl+Shift+A) - memory persists between sessions.

Clear Memory

Clears the project selection memory. Use when you want to reset the stored selection to empty. Run the tool (QC) and memory for the current project is cleared.

Load from Memory

Recalls a previously saved selection from memory. Use when you need to re-select a specific set of elements you stored earlier. Run the tool (Ctrl+Shift+R) to select all elements currently in project memory.

Next in Memory

Selects the next element in the stored selection list. Use when cycling through stored elements one by one. Click (Q1) to select the next element; Shift+Click opens the Settings Hub.

Previous in Memory

Selects the previous element in the stored selection list. Use when cycling backwards through stored elements. Click (Q2) to select the previous element; Shift+Click opens the Settings Hub.

Remove from Memory

Removes the currently selected elements from project memory. Use to refine a stored selection by subtracting specific items. Select the items to remove, then run the tool (QK) and they are deducted from memory.

Save Memory as Selection

Saves the current selection memory as a permanent Revit Selection Filter. Use this to convert a temporary memory selection into a reusable Selection Filter for view visibility control. Run the tool (Q3) with memory populated.

Save to Memory

Overwrites project memory with the current selection. Use to save a specific selection set to memory for later recall. Select elements, then run Save to Memory (Ctrl+Shift+W) - the previous memory contents are replaced.

Purge Memory Files

Deletes all temporary selection memory files (*.pym) from disk. Use when freeing up disk space or doing a hard reset of every project's stored memory. Run the tool (Q4) - all memory files are removed.

Precision Pick and Select

Narrow your selection to exactly the elements you need without manually filtering afterward.

Pick -- Precision Selection

Select elements by category without picking up unrelated geometry. Pick opens a category-aware picker that filters clicks to only the category you choose -- no need to Tab-cycle or post-filter. The dropdown includes Pick Detail Elements (keep only 2D detail items) and Pick Model Elements (keep only 3D model elements).

Key features:

Category-aware click filter with live status bar
Box-select mode for area picking
Dropdown variants for detail-only and model-only filtering

How to use:

Click Pick and choose a category from the popup.
Click or box-select elements in the view -- only elements of the chosen category are selected.
Press Escape or right-click to finish.

Filter Tools

Refine an existing selection by removing elements that do not match a condition. Select a broad set first, then apply one or more filters to narrow it down.

Tool	Action
Keep Elements Hosted On Linked Model	Keep only elements hosted on linked models; discard all others
Keep Mirrored	Keep only mirrored elements (useful for handedness checks on doors and windows)
Keep Painted Elements	Keep only elements with painted faces
Discard Grouped Elements	Remove grouped elements from the current selection
Discard Pinned Elements	Remove pinned elements from the current selection

Select By Type

Expand a small selection to all instances of the same family, type, or category. Start by selecting one or more representative elements, then use these tools to find every matching instance.

Tool	Action
Select All Elements Of Same Family	Expand selection to all instances of the same family in the project
Select All Objects Of Selected Type	Expand to all instances of the selected type
Select Element Types	Choose types from a dialog to select all instances
Select Similar Elements In Active View	Multi-element "Select All Instances" scoped to the active view
Select Group Elements	Select all elements within a group instance
Select SubWalls	Select sub-wall components of stacked or composite walls

Select By Condition

Select elements based on their relationships, tags, or other conditions rather than spatial picking.

Tool	Action
Invert Selection	Switch your focus to everything you haven't selected in the active view
Add Tagged Elements	Add the tagged element for each tag in the current selection
Find Entities Without Tags	Select visible elements that are missing tags
Find Entities Without Dimensions	Select elements missing dimension references
Select All Text Notes	Select every text note in the active view
Select All Vertical Reveals	Select all vertical reveals in the active view

Select Revision

Work with revision clouds and their associated metadata.

Tool	Action
Select All Clouds Of Specific Revision	Pick a revision to select all of its clouds
Select All Clouds with Same Comment	Select revision clouds sharing the same comment text
List Selection as Clickable Links	Generate a navigable list of selected elements for reference

Select Revision Clouds

Selects all Revision Clouds associated with a specific Revision. Useful when bulk editing comments or parameters for every cloud in a single issuance.

Key features:

Picks a Revision from a list and selects all of its clouds at once
Scoped to the current model

How to use:

Run the tool (Q6).
Select a Revision from the list.
All clouds for that revision are selected.

Select All Clouds with Same Comment

Selects every Revision Cloud in the model that shares the same Comments value as the currently selected cloud. Useful for finding all clouds marked with a specific note (for example, "Coordination Issue").

Key features:

Matches on the Comments parameter across the whole model
Works from a single seed cloud

How to use:

Select a single revision cloud that has a comment.
Run the tool (Q7).
All matching clouds are selected.

List Selection as Clickable Links

Generates a report of the selected elements with clickable Element IDs. Useful for navigating through a list of elements one by one using the Pyvoid output window.

Key features:

Clickable Element IDs route to each element in the active view
Works on any selection, not just revision clouds

How to use:

Select the elements you want to list.
Run the tool (Q5).
Click an ID in the output window to zoom to that element.

X-Ray -- Visibility Diagnostics

Diagnose why elements are invisible or displaying incorrectly instead of guessing at Visibility/Graphics (VG) settings. X-Ray runs a battery of 13 condition checks -- VG overrides, view filters, phasing, worksets, crop regions, view range, Design Options, and more -- against an element-view pair, then presents prioritized results with one-click fixes. Includes X-Ray Vision mode that temporarily reveals hidden elements using transaction rollback.

Key features:

13 diagnostic checkers covering all visibility conditions
Priority-sorted results showing the most likely cause first
One-click fixes for common issues (unhide element, adjust VG, enable workset)
X-Ray Vision mode: temporarily shows hidden elements without committing changes
Batch scanning across multiple elements or views
Comparison mode: diff checker results between two views to find why an element appears in one but not the other

Getting Started

Select an element that is invisible or displaying incorrectly (use a linked view, schedule, or element ID if you cannot click it directly).
Open X-Ray from the Selection panel (or press Ctrl+Shift+X).
Review the diagnostic results -- the highest-priority cause appears at the top.
Click Fix next to a result to apply the correction (for example, unhide the element or enable its workset).
Use X-Ray Vision to temporarily reveal all hidden elements in the view for context.
Switch to Compare mode to diff two views and find configuration differences.

UI Overview

Area	Description
Element info header	Shows the selected element's category, family, type, and ID
Results list	Diagnostic findings sorted by priority with severity indicators
Fix buttons	One-click corrections for each fixable condition
X-Ray Vision toggle	Temporarily reveals hidden elements via transaction rollback
Batch/Compare tabs	Switch between single-element, batch, and comparison modes

Tips

Start with X-Ray whenever an element is missing from a view -- it is faster than checking VG manually.
Use Compare mode when an element shows in one view but not another to find the exact setting difference.
X-Ray Vision does not commit any changes -- it uses transaction rollback, so your model stays clean.

Isolate -- Category Isolation

Quickly focus on a single category without navigating the VG dialog. Isolate opens a popup menu of categories present in the active view. Select a category to temporarily isolate it; select "Reset" to restore full visibility.

Set Workset

Assign selected elements to a different workset via a dropdown picker. Select elements first, then run Set Workset and choose the target workset from the list.

View Toggles

Toggle persistent view behaviors on and off. These tools use the SmartButton pattern - the icon state reflects whether the feature is currently active.

Tool	Action
Sync Views	Toggle synchronized pan and zoom across open views -- navigate in one and the others follow
Tab Coloring	Color-code document tabs by project file for quick identification in multi-document sessions
Minify UI	Hide standard Revit ribbon tabs to maximize drawing area; Pyvoid tab remains accessible

Diagnostics

Tools for inspecting view settings and saving selections for later use from the Pyvoid Toolkit Selection panel.

Tool	Action
Section Box	Create or adjust a section box around selected elements in a 3D view
Save Memory as Selection	Promote the current memory contents to a permanent Revit Selection Filter
Purge Memory	Clear all stored selection memory data from the project
