How To Add Elevation Points To A Drawing In Autocad
AutoCAD drawing files can be used every bit a terrain superlative data source in the post-obit formats:
- Profile lines
- Peak points
- AutoCAD Civil 3D terrain surfaces†
- Bentley MicroStation terrain surfaces†
- LandXML Tin can terrain surfaces
The post-obit sections draw these elevation data sources in detail. Refer to this section on how to add an AutoCAD drawing file as a data layer.
Contour Lines for Cutting Cross Sections
AutoCAD drawing files containing contour lines can exist used to determine cross section geometry when cut cross sections. In the Extract Elevation Data section contained within many of the create cantankerous section dialog boxes, the user tin can select the AutoCAD layers containing contours for use in extracting cantankerous sections.
Contour Lines as Terrain Elevation Surface
AutoCAD drawing files containing contour lines can exist used for generating a terrain surface for intersecting the computed water surface when determining the inundation map and to determine cantankerous section geometry when cutting cross sections. See this section on how to generate a terrain surface.
Top Indicate Data equally Terrain Acme Surface
AutoCAD cartoon files containing elevation point data can be used for generating a terrain surface for intersecting the computed water surface when determining the inundation map and to decide cross section geometry when cutting cross sections. Encounter this section on how to generate a terrain surface.
LandXML TIN Surfaces as Terrain Elevation Information
The software tin can utilise AutoCAD Ceremonious 3D, Bentley MicroStation, and other TIN surfaces to make up one's mind cantankerous department geometry when cutting cross sections. TIN surfaces are imported as LandXML files.
To load a LandXML terrain surface, from within the Map Data Layers console right-click and select Add Layers from the displayed context menu. And so, select the respective LandXML TIN surface file to load. The TIN surface volition be loaded and displayed as a layer.
The LandXML surface can exist used to determine the cross department geometry when cutting cantankerous sections. In the Extract Elevation Data section independent within many of the create cross department dialog boxes, the user tin can select the Can surface for use in extracting cross sections.
Currently the software cannot intersect the computed water surface direct with a Tin terrain surface. The user needs to generate a terrain surface from the TIN surface in order to generate a flood map.
