Have you ever drawn a line from a point node and become frustrated because the Z value of the line absorbs the elevation value of the point?  Next thing you find that you have a drawing with a bunch of lines all drawn at different elevations.  Yes, there are times you want this, but there are also times you don't.   If you decide that you need to draw several lines from several point nodes and you want to guarantee the lines will be drawn at a 0.00 elevation then set your OSNAPZ system variable to 1.  The OSNAPZ controls whether object snaps are automatically projected onto a plane parallel to the XY plane of the current UCS at the current elevation.   0 - Osnap uses the Z-value of the specified point 1 - Osnap substitutes the Z-value for the specified point with an elevation set for the current      UCS If you choose to have your elevation something other than 0.00 then type in ELEV in at the commandline and set the desired value.  WARNING:  The OSNAPZ is a system variable and therefore, when ...

(Part 2 ) In this part we will create the same surface from a civil 3D points file that was exported in the NEZ (Northing, Easting, Elevation) .txt format. This file will allow users to create a toposurface in Revit. The format is key as well, as is the file type you are importing. You can import this points file in either (.csv or .txt) file type formats. Keep in mind you will not see the imported points until you "Finish" the toposurface.  Following these simple practices will ensure your civil files are exactly what you need and will not break your projects. The civil CAD file needs to be in the following formats to work. (DWG, DXF, DGN) The civil points file needs to be in the following formats - (NEZ - Northing, Easting, Elevation) Import the CAD file into a basic template to test its usability and review stability / file size. Remove the CAD file after converting into a toposurface.  Clean up ...

I'm rehashing this one because a user asked me if it was possible to create a profile from a feature line.   I must give credit where credit is due. My good friend, Phillip Lynch, showed me this cool feature. Scenario: so you’ve been given a set of points in line and have been asked to generate a profile from those points only. You don’t have an existing surface, nor do you need one. All you need is the profile of just the points. Problem: you cannot create a profile without first sampling an existing ground surface. Problem solved. . . First, generate a feature line from those points. This can be done with a 3DPOLY that you connect from node to node and then converting the 3DPOLY to a feature line or by manually drawing a feature line from node to node. The node object snap must be used to absorb the point elevation: Then select the feature line to active the context sensitive ribbon. In the ribbon you’ll find the quick profile tool: In the “Create Quick Profiles” dialog box set your styles as ...
