capitaldesigns 3 Posted November 5, 2020 I am working on a project with a flat lot. The rear part of the lot drops straight down -14" . I am trying to draw this using terrain perimeter and the elevation region to show the 14" drop. When I select the elevation region and input in the elevation as -14" the terrain perimeter also move down -14" along with the elevation region. I have tried this a number of way with the same results. I have no idea what I am doing wrong. Share this post Link to post Share on other sites

capitaldesigns 3 Posted November 5, 2020 I drew a guest house then placed the terrain perimeter. In the DBX it shows the grade is 8" below the finish floor of the guest house. Where do I go to change the grade elevation of the terrain perimeter as 0" ? Share this post Link to post Share on other sites

Likely you need to leave the 8" setting alone. It is just that chief needs two pcs of information to create a slope.... Actually 3 pcs. Top elevation, Bottom Elevation and distance between the two. So give it a try with one region at 8" and the other at -6" with a small gap between them giving you a 14" difference (slope). Edited November 6, 2020 by Chopsaw Sorry long day and short night. I think that should be -8" and -22" Share this post Link to post Share on other sites

I have tried this a number of way with the same results. I have no idea what I am doing wrong. You need a minimum of 2 Regions to "move" the Terrain. The Terrain Perimeter (T.P.) itself will auto set it's own height to begin with depending on floor structure thickness, but can be set as needed ( uncheck automatic height - not Build ) for the particular Project. Terrain Regions register off the T.P. height and should show 0" when 1st placed. In this case put a Terrain Break with the transition set at 0" between the two Regions, which are drawn nearly touching each other for a steep/straight drop. M.
