Autocad Contour Lisp Average ratng: 5,3/10 8302 reviews Mar 29, 2012 - This routine is helpful if you have overlapping objects that form a closed area and you would like to combine them into one overall closed object. I am using ACAD 2000 to draw a plan view of a terrain. My existing contour lines were drawn with polylines. I would like to drawn an intermediate elevation countour line without calculating positions(via interpolationg) between two known countour lines. Any idea,please remember LISP in not my forte. How to draw contour lines in AutoCAD?You can easily draw contour lines within AutoCAD using the Contour Module of ESurvey CADD. Step by Step Procedure to Gen. You can can add contour lines to a raster-based surface in your map to create a contour or topographic map. You add contour lines to surface layers in Display Manager. To create contour lines In Display Manager, right-click a surface layer, and select Create Contour Layer. In the Generate Contour dialog box, enter a name for the new Display Manager layer that will contain the contour lines.

It does not work well in this lisp code. The label displayed twice in close polyline. I should label one in close polyline.

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. You obviously cannot directly generate digital terrain model (DTM, topo) from such source data. But a simple LISP utility can simplify generating a terrain model in AutoCAD Civil 3D or AutoCAD.Free

A sample data can be download from the drawing file LOM.DWG for Civil 3D 2008.

The LISP utility CHELEV (command CHELEV) can easily assign proper elevation (Z) to a set of contours. Just pick two points connecting a line climbing across the contour set and specify the bottom elevation and the contour step. The CHELEV.LSP file can be downloaded from www.cadstudio.cz/download. Load it into AutoCAD e.g. with APPLOAD.

The sample drawing contains an example of countours all placed in the zero elevation, Z=0. 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 contour step is 10 (m) in this example.

As 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). Use the CHELEV command and specify all 3 necessary connecting lines and their parameters (for monotonous terrains a single connection is enough).

As 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):

Beside Civil you can also create the terrain model using the utility DTM for AutoCAD.
