Stairs, Ramps, and Railings - Autodesk Revit Architecture 2015 Essentials - page 112

Designing ramps
Now that you're familiar with designing a number of stair configurations,
ramps should come easily since they are based on the Stair by Sketch tool. It's
the same basic process of sketching a desired shape and then completing the
sketch, with one major difference: far more frequent landings and a shallower
slope.
You access the Ramp tool on the Circulation panel on the Architecture tab.
Keep in mind that ramps have different constraints than stairs based on slope
and length. Understand that the maximum length of a ramp in one section
is 30 ′ -0 ″ (9000 mm) with a 1:12 slope (8 percent). These parameters can be
changed, but by default they correlate to common code requirements.
In the following exercise you will create a straight run ramp between Level 1 and
Level 2. Because you're traversing Level 1 to Level 2 (and they are 10 ′ [3000 mm]
apart), this will require a ramp length of 120 ′ (36,600 mm) at a maximum 1:12
slope, not including landings.
exercise 4.8: Create a ramp and edit the
Boundary
To begin, go to the topic's web page at www.sybex.com/go/revit2015essentials ,
download the files for Chapter 4, and open the file c04-ex-4.8start.rvt .
1. Open the example file to the Level 1 view.
2. Select the Architecture tab, and choose the Ramp tool from the
Circulation panel.
3. In the Properties palette set the Ramp Type to Ramp 1; the Base
Level is Level 1 and the Top Level is Level 2.
4. Using the Run Draw tool, add straight runs similar to Figure 4.28.
5. To get all the landings and ramps into the right location, select the
boundary and riser lines after creation and move them using the
Move tool on the Modify panel.
The ramp should look similar to the image in Figure 4.28.
