Hi guys iam new to revit just getting my head around it, i was woundering if someone can help me understand Revit site in genral

like when drawing a site contours using inserted image that has the site contours on it and start following up the contour elevations using revit massing & site, DO you start with the image contours elevation first or start by drawing elevation of zeros first like what Revit wants and than put down the site contours elevations from the image, i always end up with a wrong site section which is different from what i want it to look like

Many thanks in advance

If you have a CAD drawing of the site and it has 3D CAD lines for the contours, simply import the CAD and use the "Create topography from import" tool. 

The HELP explains this process - You should always look there first:

To use imported 3D contour data

You can automatically generate a toposurface based on 3D contour data imported in DWG, DXF, or DGN formats. Revit Architecture analyzes the data and places a series of elevation points along the contour lines.

Work in a 3D view for this procedure.

1. On the Modify | Edit Surface tab, click Tools panelCreate From Import drop-down (Select Import Instance).
2. Select the imported 3D contour data in the drawing area.

   The Add Points from Selected Layers dialog displays.

3. Select the layers to which you want to apply elevation points, and click OK.

Thanks for your reply iam familar with working on dwg site plan and how to insert them,

we dont get dwg or any other format to work on site plans the architec just sketch how the site might look like and than we just go online using  google GIS maps) and find the site addres and than copy it as image format than insert it into revit.

for example the inserted image got four contour lines that runs around the site each goes like 5m,10m,15,20m apart lets say the site overall shape is a rectangular box how to make this happen what goes first, should i start by elevation of zeros first and than use the contours numbers

the problem is i dont know how to start this process, should i use elevation of zeros first around the boundary of the site and than put down the elevation numbers from the image? because everytime i end up with a different site section from the architec sketch

i know iam missing a really small thing on this but its confusing me alot, and iam running out of time

yet again thank you for your time

Whtever the countor line is, just place points at that elevation along it, including if it crosses the property line.
