Can you create a surface from polylines in Civil 3D?

How do you turn a polyline into a surface in Civil 3D?

On the Prospector tab of the Toolspace, right-click on Surfaces and select >> Create Surface.

1. Confirm that TIN surface is selected as Type.
2. Select the desired Surface layer and Style.
3. Click <> to close the Create Surface dialog box.
4. On the Prospector tab of the Toolspace, expand the Surfaces node.

How do I convert 3D polyline to surface in AutoCAD?

You can use the SURFPATCH command to convert a closed 3D polyline to a surface patch (3D surface). The command option _Curves and selection of the boundary control curve will create a patch surface associative to this curve.

How do I change a polyline to a surface in AutoCAD?

Click Modeling tab > Surface panel > Convert to Surface. Select the objects you want to convert and press Enter. You can convert 2D solids, meshes, regions, planar 3D faces, and polylines, lines, and arcs with thickness.

How do you add a polyline to a surface?

Open the AutoCAD Properties palette, select a polyline, and note that the elevation of that polyline is not 0.00. If you have polylines without elevations, they must be modified to the correct elevation before placing them into your surface. Also, once they are placed in your surface, you cannot delete them.

How do I create a new surface in Civil 3d?

Go to the Prospector tab in Toolspace and right click on Surfaces, select Create Surface. Alternatively, you can type CREATESURFACE at the command line.

How do you make a 3d surface in Autocad?

Choose a Surface Creation Method

1. Create surfaces from profiles. Create surfaces from profile shapes composed of lines and curves with EXTRUDE, LOFT, PLANESURF, REVOLVE, SURFNETWORK, and SWEEP.
2. Create surfaces from other surfaces. …
3. Convert objects into procedural surfaces. …
4. Convert procedural surfaces into NURBS surfaces.

How do you turn polylines into contours?

Create a surface, open the definition tab, add the polylines (that have valid elevations) to the surface as Contour data. Note that contour data alone is not a preferred way to define a surface as breakline, point data and boundaries are absent and likely played a role in creating those polylines you call contours.

How do you make a polyline into a 3D face?

If your polyline border contains arc segments, you may want to refine the resulting mesh with the MESHREFINE command. This will increase the density of the small patches and more precisely fill in the arcs. The mesh can be easily converted to 3d face entities (3DFACE) just by exploding – the EXPLODE command.

How do you make surfaces from contours in Civil 3D?

You can add contour data to an existing TIN surface. For best results, add the contour data in a single operation. In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click Contours, and click Add.

How do you combine two surfaces in Civil 3D?

No file posted but, here are the steps to merge surfaces.

1. On the Civil 3D Toolspace, click on “Prospector” tab.
2. Right mouse click on “Surfaces” and create a new surface.
3. Expand the “Definition” subfeature for that new surface and right click on “Edits”.
4. Click “Paste Surface” and chose the original surface.
