Stairs & Railings

NB. System Families are like components. Must 'Edit Type' and 'Duplicate' when changing anything or it will be a global change.

Stairs
Most comfortable riser height = 175mm
Width for public stairs = around 1.2m
Tred 300mm
Stair tool:

• L Shapes, must add an extra stair to the landing area (odd Revit thing), ie. offset by one extra stair when turning around (see examples in 'Friday practice")
• If changing the riser number, always check the tread depth again as Revit will reset to a very shallow tread of 250mm.
• Add a reference plane half the width out from your side (eg. wall) so you can trace over it
• Put in the first set of stairs then 'multistorey' them

Railings
When recreating railings (ie. if you delete them), when sketching them back in, use the pick line tool so it automatically creates a new line for each change in height. Always reference the railing being redrawn to the stair, not the stringer (ie. inside line not outside line), then move over using the flip tool.

If you want to just sketch some railings (eg. for a garden path or similar) with not associated stairs (don't do this often):

• new line for each change in direction/slope
• click on the line representing the slope and select 'sloped' in the options bar
• pick the next line representing the flat bit at the top of the slope and create a custom height (options bar) eg. 1m
• NB. can't get rid of the railings that project down to 0 point in this instance, have to hide within a wall/site/typography instead

Steps or similar
Use building pads or slabs - much easier and simpler and will create a better profile.
For seating:

• 500mm down by 1000mm across (seat plus area to walk behind)
