Revit wall won't join
Walls only join at ends that allow it: right-click the wall-end grip → Allow Join. Then use Modify → Wall Joins to pick Butt, Miter or Square off, and check both walls use the same location line and level.

Your corner walls won't join. Here's your plan:
- Allow Join at the wall end
- Set the join to Butt
- Check the location line

The Revit problems students get stuck on — and the fix
Floor or roof error: lines must be in closed loops
The sketch must be one closed loop with no gaps or overlaps. Use Pick Walls, Trim/Extend to Corner on open ends, and delete any duplicate lines.
An element isn't showing in my Revit view
Check the View Range (cut plane), Visibility/Graphics (VV) for its category, the crop region, the view's phase and detail level — and Reveal Hidden Elements in case it was hidden in the view.
Rooms won't place or room tags don't show
Rooms need room-bounding walls or Room Separator lines around them, in the same phase as the view. Place the rooms, then tag them with Tag All.
I can't dimension what I want in Revit
Press Tab to cycle through references (wall faces, centres, cores) before you click. A closed padlock on a dimension locks it — unlock it to change the value.
How do I set up sheets and export a PDF?
View → Sheet with your title block, drag views onto it, then File → Export → PDF and pick the sheets to include.
Levels or grids don't show in some views
They only show where their extents reach. Drag the extents across, or use Propagate Extents to copy them to parallel views.
My Revit roof comes out wrong
Roof by Footprint uses the edges you mark as slope-defining; untick the rest. For a single slope or a profile, use Roof by Extrusion. Then attach the walls to the roof with Attach Top/Base.
My schedule is missing information
A schedule only shows parameters of its category. Add the fields in Schedule Properties, and make sure the parameter exists in the family or as a project parameter.
A family won't place
Hosted families need a host — a wall, floor or face. Choose Place on Face or Place on Work Plane, or load a non-hosted version of the family.
How do I bring in a DWG?
Insert → Link CAD, set the units and Auto – Origin to Origin, and tick Current View Only for a 2D underlay.
Revit stairs won't create
Set the base and top levels first, then check the maximum riser height in the stair type — if the floor-to-floor height needs more risers than the run allows, the stair can't complete.

What it costs vs a tutor
A private Revit tutor
£15
for about fifteen minutes, when you can book one
Cadet
£2.99
for a whole night before a hand-in — or 5 free sessions every week
Don't pay £500 for a CAD freelancer. Learn it in one night for £2.99.
A freelancer takes weeks, costs hundreds, and hands you a file you can't explain in a viva. Cadet sits with you in your own model and shows each step, so the work — and the understanding — is yours.
Cadet never does the work for you.
It shows the step; you make the click. That's why departments can recommend it.
