I know this is probably a stupid question but……….. when drawing walls do you?

A:            draw a wall for each level of the building. This means that a join line will be visible at each level.

Or

B:            Simply draw one wall covering all levels. This will mean that wall will appear cut-through at each of the various level views i.e. a plan which is a horizontal section.

Why does Revit, unlike AutoCad does not have a layer structure? When you build up a really complicated building, how are you going to navigate your way around the thing without being able to turn some of it off?

Do not draw a wall for each level. You draw one continuos wall and then your use view ranges and your levels determine where your cut level is. 

I think you need to spend some time with tutorials and your help file.  This is NOT AutoCAD. You an turn off model elements in the visability graphics.  You will most likely also want to look into view templates.

Basically, you should model like you build.  Interior walls are by level.  Often, our exteriaor walls are full height.  Even if your exterior walls are by level, you can join them and the horizontal split line will go away if the face is in the same plane and exterior surface is the same material.

Layers are awful!  No quick answer here because of multiple methods but embrace Revit and learn how it works.   Revit's method of control is far easier than layers.

Draw/Model it like it will be built.  i.e. Exterior walls (like curtain walls) are typically a giant wall (unit).  So those would go from level 1 to roof (or however the design is laid out).  However, interior walls, regardless of whether they line up in plan, should be on a level by level basis. (think contractor's QTO estimates on level by level basis)  If you need to line them up, go to your properties menu and turn on overlay floorplan and select the floor you want to overlay.  i.e. 1st floor on top of 2nd floor to temporarily see where things line up.

If you draw a wall continuous from level 1 to level 3, it will be presumed that you meant to do that, so it'll get built that way.  HUGE mistake.  There will not be structure to support a floating floor, the contractor will estimate it wrong (not his fault either!) and if you cut a section through that area it will be incorrect.

Model it like it is in real life and you will be ok.

OK Thanks for help.

I have tried using the join command under modify to no avail. I  cannot Boolean to get rid  of the horizontal split.

Also can anyone point me in the direction of a good video tutorial  on visibility in Revit. I am aware of command such as temporary hide and filters but I have yet to get this working as clearly as AutoCad layers.

Use your HELP file.  It will really help guide you.  You need to forget about AutoCAD as comparing Revit to CAD will only complicate things further.  You can shut off families in your visability graphics, just type VV or VG.

If the join command doesn't work then either the materials are NOT the same or the exterior face does NOT line up.  I would bet the later.  Cut a section and align one wall to the other using the exterior face, then use the join command in elevation.
