Pointing the way→

Revit 2010 introduced a new annotation symbol. The spot slope. The Revit documentation shows this symbol as an arrow or triangle as is usually used in a wall section. However this annotation can do more than just that.

Recently I discovered slope arrow doesn’t just show roof slopes in elevations and sections, it also works in plan views. Since the release of Revit 2010, I haven’t had reason to use the spot slope annotation. Most of the projects I have been working on this year have been renovations and already under construction. During some recent revisions to a project however I decided to check out this new tool in Revit and was delighted to discover how versatile it is.

As I mentioned earlier the spot slope can also be used in plan view. It will draw an arrow in the direction of the slope and show a note above the arrow indicating the amount of slope exactly where you clicked on the geometry. The spot slope annotation can be used on almost any geometry. Roof slopes or curves, topography, walls (with sloped tops), structural beams and floors are a few I have tried. I also tried ramps but for some reason the annotation COULDN’T find the slope of the ramp in plan view only in elevation. I haven’t found out why yet.

In plan view the annotation only shows as an arrow, however in section or elevation it can be shown as either an arrow or triangle. Drag grips appear after you have placed the annotation that will allow you to adjust the size and location of the annotation. In addition the units can be changed. Units can be set to show percentage (good for grading plans), 1 in xx, or inches per foot. The indicated direction of the slope can be changed (up or down) as can the text and leader options (same options as with text notes). Additional text can be added to prefix or suffix the slope amount (IE. fall or ramp down).

That’s it for now. See you next week.
