RAMP LIMITATIONS

Ramps work in a similar way to Stairs by sketch.

Maximum gradient and ramp length are set for each ramp type (e.g. max gradient 1 in 14, max. length 9000), then bottom and top constraints are set for each individual ramp (e.g. bottom as Level 1, top as Level 2). Landings are automatically created between ramp runs.

WHY USE RAMPS

Ramps are useful if you need to quickly generate ramps that can be easily changed. The alternative is to use sloping Floors (floors with a Slope Arrow), but they are much more work as each segment has to be created separately, and lengths, heights etc worked out manually. Ramps do all this for you.

Railings are easier to manage on ramps as well. Using sloping Floors means a railing has to be manually drawn for each ramp segment.

Curved ramps are best done as Ramps in Revit.

The general rules are:

Use sloping Floors for simple ramps without railings (e.g. car park ramps).

Replace ramps with sloping Floors once the ramps dimensions and set-out have been locked down.

RAMP LIMITATIONS

Like stairs you need to create construction lines before creating ramps. Ramps are drawn by their centre line, and you can't input distances between drawing ramp runs so you can't nominate specific landing lengths.

Ramps are not visible in Reflected Ceiling Plans unless the view's Cut Plane slices through the ramp. Even then it shows the ramp dashed.

- a work around is to show the plan as an underlay in the RCP view.

- you can also change the Ramp subcategory graphics. Change Ramps Beyond Cut Line and Stringers Beyond Cut Line.

Ramps do not show themselves as cut in plan views. You see the whole ramp. Subcategories Ramps Beyond Cut Line and Stringers Beyond Cut Line seem to have no effect.

Ramps tend to not hide things immediately below them in plan views.

- you have to manually hide them in each view.

You can't put a Spot Slope reference on a Ramp.

- you can place them on ramp landings and then move them to a sloped part of the ramp.

(make sure you move the whole Spot Slope, not just the test location).

You can only put Spot Elevation references on landings, you can't put them on sloping ramps. This is in all 2D views (plans, section etc.)

In 3D views you can put Spot Elevations on the edges of ramps, including sloping edges.

RAILINGS AND RAMPS

Ramps place railings automatically. If your ramp has landings make sure railings used on ramps have type parameter Use Landing Height Adjustment set to No.

Railings on Ramps must have separate lines for sloping parts and landings. Railings created when a ramp is drawn will be correct, but if manually draw railings be aware of this limitation.
