There are number of productivity killing bugs in Revit 2026.1
I noticed this started in R2025 and it is still there in R2026:
The "Split Gap" command does not do anything.
You click the icon, and try to select a line to split and then nothing happens.
The work around is unproductive where you select the split icon, select 2 points, then delete the unwanted line to create a gap.
When editing a wall to create wall panels.
Say you have a cladding panel that is eg 1200mm x 3000mm, and you want those panels to have a gap of 20mm between them. The top lines of the panels keep automatically moving one line in the gap to the adjacent line, closing the gap when you try to fillet the corners, particularly when the top line is at an angle.
When you fillet this:
This happens:
There used to be 2 vertical lines here, but the one on the right automatically moved to the one on the left.
I can't see where where that suggests the lines are locked together, so I don't see a reason why the lines of individual "rectangle cladding panels" should automatically join together. They should remain as individual lines that can be trimmed, filleted, etc...
The trim function ends up with the same problem.
It only seems to happen when the top line is at an angle.
Even the align function does weird things.
For example I copied all the rectangular panels above the lower ones which saw them above the angled roof line.
I used the align command to align the top horizontal line with the roof slope. That worked for the first panel.
When I did it for the adjacent panel, that panel top line aligned with the roof slop, except then the angled top line of the previous one I just changed automatically changed to horizontal, that same with the next one and the next one.
I am trying to avoid having to create individual cladding panels and then arraying them over the wall face.
One other annoying bug is that when you want to change the size value in the properties box using the number pad on your key board, Revit no longer allows you to highlight the value and delete it or use the backspace button. Sometimes it thinks you want to delete the component and deletes it so you have to undo, then select the value you want to change again somewhere in the middle and hit the back space button then sometimes it deletes the number or allows you to add the numbers you want and then delete the numbers you don't.
