Usually in the center of the ramp or stair.
Roof vignette slope arrow.
Note that only flat roofs are supported by this tool.
Ramp slope and stair direction arrows may be up or down so require a notation up down at the base or along the line of the arrow.
The slope arrow tool creates sloped surfaces.
This vignette has quite a few elements to coordinate and manipulating the roof slopes can be a little confusing at first.
The arrows do not extend from the ridge to the eave.
Roof slope arrow is a tool that allows you to modify slopes on roof elements by defining start elevation and slope or end elevation.
For this vignette you will need to layout a roof plan showing all the elements required by the program.
Roof slope arrows are only shown in plan view and always point down.
You can use a slope arrow for the following types of elements.
Multiple roof slope arrows can be added to a roof and connected to each other.
Roofs soffits floors structural floors building pads ceilings for example to create a flat sloping roof draw a slope arrow from the lower edge to the upper edge of the roof boundary.
Use slope arrows to define slopes on a roof such as a 4 sided gable roof.
