From the scene, in the Contents pane, select Add Elevation Source. Create alignments from objects4m 11s. 99Civil 3D Essentials Book and Practice Files. Masks are helpful with the time generation issue by creating a window in which the surface is displayed. Under Select Elevation Attribute Tag, we select the tag that contains the Elevation.
Create a new Surface; right-click on Surfaces in your Prospector tab of your Toolspace --> Create Surface, as shown below. Apply a profile design check set3m 15s. Civil 3D surface analysis: elevations. According to the Autodesk Civil 3D Help file: A snapshot is a surface operation that captures the current state of surface. Creating a single surface in Civil 3D from 90 million points would take a massive amount of time (if it was even possible) so I decided to test this on a smaller scale.
I hope you find this Surface option useful in your projects when building and editing surfaces. Bring up the layer management window by clicking on the layer manager button on the ribbon or by typing layer on the command line. TIN lines will be drawn along the contours to maintain control over the shape of the entities representing the contours. The layer has points for all the surfaces in the DWG file. Example of toggling between surface boundaries: These are examples of the Civil 3D tools available solely within the surface controls. In the example the tag is ELEV2.
What does that little icon mean? It analyses the water behaviour on the surface, giving us boundary points, boundary segments, depression, flat areas and multi-drain points. If there is a lot of inconsistencies in the data (the stream in this example), I would probably go with the Civil 3D surface. Practice while you learn with exercise files. And for now that's all we need. Note: You can find the unique value of the surfaces from the drop-down list. The Surface Defined. Note: As this layer may have a significant number of points, turn off the visibility for now. Let me know what you think in the comments! Once the point cloud is in the drawing, select it and, on the contextual ribbon tab, choose the command, "Create Surface from Point Cloud". The course includes the full civil 3D essentials book and practice files.
The bottom line is you don't know what you don't know. Supplementing factors will add vertices to a boundary or contour segment. Civil 3D Essentials4. In this case we cannot send this out, work needs to be done.
In both programs, I maxed out the settings to get the best possible surfaces. To do that follow the steps below: - First, create a TIN Surface the usual way on Home Ribbon tab on Surface drop-down menu select Create Surface and create a TIN Surface. We can choose to omit the display of the surface outside a boundary by designating it an outer boundary. Any of the three lines that make up the road, (edge of pavement, face of curb, and top back of curb) can be drawn and then offset to get things closer. The distance factor tells AutoCAD Civil 3D to look at three adjacent vertices. A Hide boundary masks areas of the triangulation, like punching a hole in a surface. Finally, the Existing Ground surface now appears in the Prospector's window. When you use a hide boundary, the hidden surface area is not deleted. Doing so will lead to more precise cut and fill analysis. By determining the area or areas we wish to display or exclude, and whether or not we wish to retain, use or modify the underlying data, we can then determine whether a mask or a boundary is best used in our surface model. Keep in mind that when you hit the Finish button, Civil 3D will run the simplify surface command one last time.
The final Proposed Formation surface in Civil 3D is shown in the object viewer, as per the below illustration. Boundaries – Can only be used in surface base file. Design surfaces from Civil 3D can provide an accurate foundation to the work I do in ArcGIS Pro as well as information visualizations I share as web scenes. If they are not created from a reliable field surveyed source, the data must be utilized with caution. I also do not want to see dirt moved twice because somebody got a model that had too many issues. Don't worry, we are not going to do that manually. Ditches and berms are easily flattened and there is no simple way to verify their existence. Hope you find this post useful! After your surface has been created, expand you Existing Ground surface --> Expand Definition --> right-click on Edits --> Simplify Surface, as shown below. It is a great function but ran into a interesting quirk, more like a workflow challenge.
If you are using the 3D Modeling workspace, you can find it in the Create panel on the Surface tab, as shown in the following screenshot: The planar surface command can be used to quickly create planar surfaces using one... Expand the Definition node under Surface Name. It is our job to be sure that what goes out quickly is not going to cause extra work. I repeated the process for the area around the stream. Supplementing Factors. In "Surface Properties" under the "Definitions" tab, a list of created boundaries can be toggled on and off. If I expand surfaces, you'll see EG listed beneath it. Be assured that the program will only remove points that do not affect the maximum elevation change, thus maintaining the surface integrity. 5 acres and there is a lot happening in a little spot. Edit grading objects4m 26s. Contours have one elevation their entire length. Without the proposed surface, the corridor and alignments would be displayed going through the ground or above it. The job may be dynamic. Create a Gravity network by layout5m 39s.
Retention areas can benefit from a little cleanup by installing lines on corners and bottoms. In the example we are looking at today, we've got AutoCAD Blocks with different attributes, one of which is the actual Elevation of the point. That is, when the comparison surface (finished elevations) is above the base surface (existing topo), it means that we are in fill (green in the image below). Both tools can define a surface area we wish to display or exclude and both tools can refine or remove visual elements of the surface.
Configure and apply description keys7m 22s. Boundaries can be useful to "reign in" large surface models by excluding areas we do not wish to display or to remove surface data we do not want to include in calculations. If the rectangle is added as an outer boundary with the non-destructive breakline option unchecked, we notice that the TIN lines outside the boundary are no longer displayed. It's understandable to falsely relate the Surface Build Order to the AutoCAD Draw order, but we get the idea. Non-Destructive or Not?
Weeding Contour Data. Our goal is to combine this information to obtain a surface with the levels of the proposed formation, which will be the starting point for the fill to take place. Edit a gravity network using properties4m 57s. The new TIN surface is added to the 2D Layers and rendered into the scene. When I talk about a surface, we are looking at the 3D elements that are elevated to make a model, contours, 3D lines, and points. We may want to alter the contour display in an area, such as a building pad or a detention pond. The distance value entered defines the perpendicular distance between the midpoint of an arc and its chord. The 2018 versions of the Autodesk programs have been out for a while now. Create feature lines6m 33s. A balance must be struck. Click <
