The new features with Autodesk Revit LT 2026 are present, yet, as with many new releases with complex BIM software, initial users are finding certain teething problems. It is so frustrating to encounter technical glitches in the course of a project deadline irrespective of whether you are an architect or a designer. Installation crashes and geometry tools that act in an unpredictable manner are just some of these bugs that can easily interfere with your workflow.
This guide will contain a list of the most common problems that the community reported and provide solutions that will be taken in real life and offered in a step-by-step manner.
1. Split with Gap Command Not Working
One of the most annoying bugs in the 2026 release involves the “Split with Gap” tool. Users report that selecting the tool and clicking on a linear element (like a wall or beam) results in absolutely no action, failing to create the expected separation.
Solution Steps
If you find that the Revit LT 2026 split with gap command is not working, you can use a manual workaround until Autodesk releases a hotfix:
- Select the “Split Element” (SL) command instead of “Split with Gap.”
- Click on the element where you want the split to occur.
- Manually select one side of the split element.
- Use the Move tool (MV) or the arrow keys on your keyboard to create the desired distance manually.
- Alternatively, use the “Copy” command to duplicate the element and adjust the length of both segments to simulate a gap.
- Check the Constraints: Ensure the element is not pinned (PN) or locked by a dimension, which often prevents splitting operations.
2. Properties Palette Input Glitch
A strange UI bug has surfaced where users cannot use the Backspace or Delete keys when editing numerical values in the Properties Palette. This is particularly prevalent when using the Numpad for entry, making it difficult to modify parameters quickly.
Solution Steps
Use these methods for troubleshooting Revit properties palette glitches regarding data entry:
- Focus Reset: Click inside the drawing area (the viewport) and then click back into the Properties Palette field. This often resets the focus priority.
- Top Row Keys: Attempt to use the number keys above the letters on your keyboard instead of the Numpad.
- Variable Highlight: Instead of trying to backspace, double-click the value to highlight the entire number, then type the new value directly over it.
- Docking Reset: Undock the Properties Palette by dragging it to the center of the screen, input your data, and then redock it to the side. This forces a UI refresh.
3. Trim/Align Tools Malfunctioning on Angles
The Trim/Extend to Corner (TR) and Align (AL) tools are fundamental for cleaning up geometry. In the 2026 version, users have noted that these tools fail or produce bizarre geometry when working with non-90-degree angles or complex wall intersections.
Solution Steps
If the Revit trim extend tool is not working properly on angled connections, try these corrective actions:
- Check Wall Joins: Select the wall intersection, look for the small blue grip indicating the join, right-click it, and select “Disallow Join.” Then, manually drag the wall ends to meet.
- Adjust View Range: Ensure the cut plane of your view is intersecting the walls correctly. Sometimes visual errors look like geometry errors.
- Manual Drag: Instead of using the Trim command, select the wall and drag the blue dot (end handle) until it snaps to the target reference line.
- Element Constraints: Verify that the walls are not constrained to conflicting levels or reference planes that make the physical trim impossible.

4. Deployment Error: Missing Schema Folder
This is a specific error for IT managers or users creating custom deployments. The installer fails with a message that the “Schema” folder is missing from the Common Files directory. This prevents the software from loading standard libraries and templates.
Solution Steps
To fix the Revit 2026 missing schema folder deployment issue, you must manually reconstruct the directory path:
- Navigate to C:\Program Files\Common Files\Autodesk Shared.
- Right-click and create a new folder named Revit Schemas 2026.
- If you have a working installation on another machine, copy the contents of this folder from that machine to the one with the error.
- If you do not have another machine, run the Revit installer again and choose the “Repair” option rather than “Install,” which often forces the recreation of missing directory trees.
- Repair corrupted Revit installation files by using the Autodesk Access tool to verify the integrity of the downloaded package before attempting the repair.
5. Double Click Settings Not Saving
In Revit LT, customization options are fewer than in the full version, which makes existing settings vital. Users have reported that changes made to “Double Click Options” (e.g., setting a double-click on a Family to “Edit Type” instead of “Edit Family”) revert to defaults after restarting the software.
Solution Steps
When Autodesk Revit double click options are not saving, it usually indicates a failure to write to the user configuration file:
- Edit Revit.ini: Close Revit. Navigate to %APPDATA%\Autodesk\Revit\Autodesk Revit LT 2026\UserDataCache. Locate Revit.ini and open it with Notepad.
- Look for the [UserInterface] section. If specific lines for Double Click actions are missing, the software may not be writing them.
- Run as Admin: Launch Revit LT 2026 as an Administrator, make the changes to the Double Click settings, apply them, and close the software normally. This often gives the program the necessary rights to update the configuration file permanently.
- Check User Profile: Ensure your Windows User Profile is not set to “Roaming” in a way that overwrites local app data upon logout/login.
Conclusion
Although Revit LT 2026 has potent BIM functionality, these bugs can potentially slow production. Always make sure that your hardware drivers are kept in line so that there is little trouble in system level.
