You should have a certain level range in mind when designing the dungeon and calibrate the challenge accordingly. Before putting the dungeon down on paper, spare a thought for the poor player characters who will be subjected to its terrors.
Image: Wizards of the Coast 3. Revisit your concept – each level should have a different flavour to the others. Multi-level dungeons should have several ways to go up or down. A one-page dungeon of five rooms with three monster encounters, a trap, a hazard and a puzzle or secret makes a good one-shot adventure location for a couple of hours of play. For bigger dungeons, think vertically as well as horizontally.
How many levels? How many rooms? Consider room dimensions, entrances and exits, and so on. A monster could also offer a clue as part of negotiations. A secret should be something interesting that requires some effort to discover. Scatter hints in the form of written clues, maps or diagrams that can hook players into looking for the secret.
Image: Wizards of the Coast 5. Large beasts will have their lair but also hunt near more vulnerable creatures. Group your monsters into two or more factions with conflicting goals. Do the troglodytes fear the nearby carrion crawlers?
Groups of intelligent humanoids will have areas for sleeping, storage, headquarters, shrines, labs and so on. Consider how monsters relate to each other. Monsters should fit your concept but have their own reasons to dwell there. Some are best left buried, after all. Image: Wizards of the Coast 7. Puzzles – such as those devised by Tasha – can help to break up combat and challenge brains instead of brawn.
Maybe the orc champion is plotting against the chieftain and cultivates their own following in secret. Player character actions disrupt the balance of power between factions and change up dungeon politics. Image: Wizards of the Coast 8. Find a reason for your dungeon to exist in the wider world – and a reason for your players to visit.
For memorable traps, try to design some that put the victims in a difficult situation. A trap that immobilises characters via adhesive or magic, for example, and sounds an alarm to alert monsters, creates a more interesting scenario than knocking off hit points.

Boundary Types: Outer o Defines the outer boundary of a surface o Triangles outside of this boundary are removed Show o Displays the triangles inside the boundary o Can be used inside of a Hide boundary Hide o Removes triangles inside of the boundary o Creates a hole in the surface o Can be used for building footprints to keep contours from crossing through them Data Clip o Keeps data outside this boundary from being added to the surface o Must be added before other surface data or moved up in priority in the surface definition o Useful for limiting the size of large datasets Lesson: Building Surfaces from Survey Data When this option is enabled it trims the TIN lines at the boundary.
When it is not used it erases all the TIN lines that touch the boundary. This can be a good option if you have good surface data on each side of the boundary as it will cut a clean and straight boundary through the surface. However, if this option is used on an outer boundary where all of the surface data is inside the boundary and the only triangle touching it are long and inaccurate, then you may be left with short triangles along the edge that are still at the wrong slope.
Breaklines Breaklines define grade breaks in a surface. They are lines in a TIN that represents a distinct interruption in the slope of a surface; like road centerlines, curbs, gutters, streams, tops and toes of slopes, or any other grade break. No triangle in a TIN may cross a breakline in other words, breaklines are enforced as triangle edges. Types of breaklines: Standard o Defined by selecting 3D polylines, 3D lines, feature lines, or splines Proximity o Defined by selecting a 2D polyline, feature line or spline o The vertices of the breakline are snapped to the nearest point in the TIN, or closest proximity o Accuracy is dependent on how close the vertices of the proximity breakline are to the points in the TIN o Can be very accurate and efficient if you have drawn the selected object from point to point Wall o Defined by selecting 3D polylines, 3D lines, feature lines, splines or by selecting points.
Weeding factors can help you skip over extra, unnecessary vertices when the data is added to the surface. While supplementing factors will allow you to sample extra points off long contours with minimal vertices.
Since by its nature, contour data tends to create flat triangles that do not accurately reflect the surface, there are several options to minimize those flat triangles. In most cases it is a best practice to enable all four options to minimize flat areas when adding contour data to a surface. DEM files are a format that is commonly used by the USGS and there is a tremendous amount of data that is available online for free in this format. This is a good option for large datasets or points that you do not need in the drawing for anything other than building a surface.
Point Groups Point groups can be used to add a specific selection set of points to a surface. It may be common that some of the points in your drawing are not related to a surface. For example, you would not want to include a point representing the invert of a manhole in the surface. A point group consisting of only surface related points is an efficient way to add only the appropriate points to the surface. Point Survey Queries Point Survey Queries are a dynamic reference to a selection of survey points that are included in a survey database.
If the points in the survey database are updated, the surface will be marked as out of date and will use the updated values when it is rebuilt.
Figure Survey Queries Figure Survey Queries are a dynamic reference to a selection of survey figures that are included in a survey database. If the figures in the survey database are updated, the surface will be marked as out of date and will use the updated values when it is rebuilt.
Exercises: Build a Surface from Survey Data In these exercises, you create a new surface from point group data. You will draw breaklines from survey points and add them to the surface. Then you will view the surface in the Object Viewer to examine it in 3D from different angles. You do the following: Create a Point Group of surface related points. Create a Surface. Draw Breaklines. Add Breaklines to the Surface. View the Surface in 3D using the Object Viewer. Points that should not be included in the surface should not be included in the point group.
Points for utility potholes or points that are part of the project for horizontal control and do not have accurate surface elevations are examples of points that should not be included in this group.
Continue working in the drawing Design. This drawing contains the Points, Alignment, Parcels, and Surface from the previous chapters. Currently only the parcel lines and labels are displayed. Reminder: You can also open the drawing with this exercise number in the Chapter Drawings folder of the dataset if you prefer a fresh start at this point. Enter Topo for the Name.
Lesson: Building Surfaces from Survey Data Confirm that TIN surface is selected as Type. Enter Survey for the Name. This layer name that includes the surface name as a suffix was setup in an earlier exercise through the Drawing Settings command. At this time the surface has not been given any data so it is not displayed.
However, it has been created and you will see it in the Prospector. This is where you will access the surface definition commands and add data to the surface Adding Point Group Data to a Surface Point information contained in a Point Group can be added to a Surface through the Prospector. Once the Point Group is added the Surface is automatically rebuilt to incorporate and display the new data. On the Prospector tab of the Toolspace, expand Surfaces. Expand the Surface Survey. Expand the Definition node under Survey.
Right-click on Point Groups under Definition and select Add. Select the Point Group Topo. This display is controlled by the surface style you selected when you created the surface. Instead, you draw the breaklines with standard AutoCAD commands, like the 3D Polyline command, and then define these objects as breaklines after they have been drawn.
Create a new Layer named Breaklines-Survey and set it Current. The drawing will now display the surface as contours and points that you will use for breaklines. You may need to Regen to clean up the display. Enter 3P at the command line to start the 3D Polyline command. Enter ‘PN to change the prompt to Point Number. Alternatively, you can also select the Point Number button Commands toolbar.
At the command line enter: and [Enter] to draw the line. Use the points in the following list of points to draw the breaklines the same way that you drew the previous line.
Be sure to use the Point Number transparent command to change the prompt to Point Number and to end the command completely after drawing each line. Also be sure to [Enter] after each non-sequential point number as shown below in the list. However, they have not yet been added to the surface as breaklines Creating Breaklines by Point Selection 1.
This will display a list of all the points used in the surface in the preview window at the bottom of the Prospector, if the Prospector is docked. If the Prospector is not docked it will display on the side. Civil 3D Downloads. Free education software Students and Teachers get access to Autodesk software Find free education software.
