Export Surface & Export Model
Civil Site Design V25 on Civil 3D & AutoCAD 2025 only has some additional functionality to directly export Civil Site Design Surfaces & Models to a variety of different formats – Export Surface & Export Model. These new commands can be found on the ribbon, however, this article explains how to operate using Civil Site Design Toolspace.
Export Surface & Export Boundary
Found in the Civil Site Design Toolspace, users can access the Export Surface command by right-clicking on the CSD Surfaces object collector or individual surfaces. In the new window, users have a large selection of format types to choose from, with the option to control the layer name of CAD based object output. Export Boundary is an existing command found on the Roads tab -> Modelling ribbon tab that has been adapted to operate through Toolspace, quickly drawing a 2D polyline of any Civil Site Design surface boundary directly in the drawing environment.
Formats:
- LandXML
- 12da
- DWG (3D Faces)
- DXF (3D Faces)
- TIFF
- IFC
- DEM
- OBJ
- STL
- Point File
- 3D PDF
Export Model
Also accessed via Civil Site Design Toolspace, users can now use the Export Model command by right-clicking on the Models object collector or an individual model. In the new window users can choose, to quickly generate 2D & 3D CAD linework of models in an external DWG or DXF, with the option to control the layer name of the polylines. Ideal as an xref into other drawings or for setting out / machine control.
Formats:
- DWG (2D & 3D polylines)
- DXF (2D & 3D polylines)
An exciting new tool in Civil Site Design v26 is the Vertical Grading Optimiser which can create vertical design profiles based on the parameters you set. Previously, the vertical best fit design profile was based on matching closely to the terrain (within preset cut/fill depths) and adding vertical curves. Mostly, you would remove these and […]
We know parking bays come in all shapes and sizes, and that many of them deserve an independently designed string (with cross sections attached to the string to describe the kerb shape of the parking bay). For those parking/bus or widening bays that can be readily described with cross section edits, we’ve got you covered […]
Non-linear design is when a typical, cross section-based design does not generate the intended result. Typically for designs that are non-parallel, such as driveways, car parks, commercial / Industrial, residential & retaining wall projects. In this webinar, our expert, Jonathan Taylor will show you how to use the Civil Site Design tools to tackle these […]
The Civil Site Design Driveway Checker can be used to assist designers with determining clashes on existing & proposed Civil Site Design project designs. In this webinar, our expert, Jonathan Taylor, will be focusing on using the Driveway Checker to check B85 & B99 vehicles over different crossing points on the project, and exploring the […]
