HOW TO MAEK CONTURES IN AUTOCAD CIVIL 3D 2014 UPDATE
Use the CHELEV command and specify all 3 necessary connecting lines and their parameters (for monotonous terrains a single connection is enough).Īs an automatic terrain ("Surface2") update is preset in this sample drawing - after you set the elevations, the correct 3D terrain model will be automatically generated (see the viewport on the right):īeside Civil you can also create the terrain model using the utility DTM for AutoCAD. The contour step is 10 (m) in this example.Īs you can see in the illustation, the generated terrain model from these "null" contours (polylines) is initially just a flat surface (you can see just its yellow outline). There are also pre-drawn sketched segments for specifying the connecting lines for CHELEV and bottom elevations in starting points of these connecting lines. The sample drawing contains an example of countours all placed in the zero elevation, Z=0. The CHELEV.LSP file can be downloaded from Load it into AutoCAD e.g. Just pick two points connecting a line climbing across the contour set and specify the bottom elevation and the contour step. The LISP utility CHELEV (command CHELEV) can easily assign proper elevation (Z) to a set of contours.

But a simple LISP utility can simplify generating a terrain model in AutoCAD Civil 3D or AutoCAD.Ī sample data can be download from the drawing file LOM.

You obviously cannot directly generate digital terrain model (DTM, topo) from such source data. If you need to use a supplied survey data to create a 3D terrain model (DTM) you can sometimes find that the input data are just 2D contours (polylines) without any assigned elevation (Z-coordinate) - just a flat plan view. If the import is 3D, maybe the missing contour lines are above your cut.( I'm not sure if this could happen but worth the check.) Look at it in 3D view.Assigning elevations to 2D contours (isolines).Video cards can cause issues similar to this.Check by turning off all model elements in VG - simple checkbox at the top. Imported CAD can be hidden under model elements.

We can't help you a lot with the information you gave.

On the Surface Tools panel you will see the Extract Objects command.

This will open up the contextual surface ribbon. I am having problems bringing in an autocad survey and it keeps making contours disappear or not show up at all Click on the Modify Tab of the ribbon and then click on Surface. I don't look in 3D for this just yet because the file is all messy when it comes in.

Contour lines in a 3D view will be off in space as you described.

So problem #1 is that if you import this into all views, the CAD is now 3D. Lets assume that your CAD file is done correctly and that your contour lines are 3D. You don't say what views you are having trouble in but I bet it is a 3D view. Tue, at 9:09:49 PM | Linking AutoCAD Site Contour missing 2014 AutoCAD drawing files can be used as a terrain elevation data source in the following formats Contour lines, Elevation points, AutoCAD Civil 3D terrain. Hi, Eric, I had a similar Issue before, I fix it with purge and audit the autocad file, and then importing to revit. Tue, at 9:05:05 PM | Linking AutoCAD Site Contour missing 2014
