What is a tin surface Civil 3D?
A TIN surface comprises the triangles that form a triangulated irregular network. TIN lines form the triangles that make up the surface triangulation. To create TIN lines, AutoCAD Civil 3D connects the surface points that are closest together.
How do you make a 3D surface in AutoCAD?
Choose a Surface Creation Method
- Create surfaces from profiles. Create surfaces from profile shapes composed of lines and curves with EXTRUDE, LOFT, PLANESURF, REVOLVE, SURFNETWORK, and SWEEP.
- Create surfaces from other surfaces.
- Convert objects into procedural surfaces.
- Convert procedural surfaces into NURBS surfaces.
What is AutoCAD 3D commands?
So, AutoCAD 3D commands like Extrude, Sweep, Revolve, Union are used by the users. Also, the user must know the importance of Viewport feature if they are working on 3D Models. The viewport command allows the user to split the drawing area into different windows to project multiple views of the model.
How do I convert 3D face to 3D in AutoCAD?
How do I change my surface to 3D face?
In AutoCAD Architecture, just select the solid cylinder, right-click > Convert To > Mass Element. Mass Elements are surfaces under the hood. So explode the Mass Element twice and you now have an array of 3D Faces that make up the cylinder.
What is 3D face AutoCAD?
Creates a three-sided or four-sided surface in 3D space. After entering the first point, enter the remaining points in a natural clockwise or counterclockwise order to create a normal 3D face. If you locate all four points on the same plane, a planar face is created that is similar to a region object.
How do you explode a 3D face in AutoCAD?
You can explode them as many times as you want, but you’re still left with 3d faces. In the AutoCAD drawing that contains the 3D faces, execute the region command and select the 3d faces. Now explode the regions that you created and you’ll have lines with 3d elevations.
