Transcript
00:09We're now going to add some alignment labels to the alignment.
00:13Right-click on the alignment and choose Edit Alignment Labels.
00:18Looking at the labeled type, you can see we can label various aspects of our alignment,
00:23stations, geometry points, design speeds, profile points, and super elevation.
00:31Adding these labels to our alignment provides information about the alignment geometry and
00:36properties in our drawing.
00:39Set the type to major stations and set the label style to perpendicular with line.
00:44You can preview the style before adding them.
00:48This will label the major stations with their station value.
00:52We want these to be displayed at every 500 feet.
00:56Now add the minor station labels as ticks.
01:00We'll display these at every 100 feet.
01:04We also want to label the alignment geometry points.
01:09These labels will mark the changes in the alignment geometry with their stations.
01:15When you add them, you can control the points you need to be labeled.
01:19Turn off alignment beginning and end and the curve midpoint.
01:26Now we'll add labels for the changes in design speed.
01:30There's only one available style for this label, station over speed.
01:36This will label their positions along the alignment, showing the design speed and the alignment station.
01:44The station index increment controls the position of the plus separator in the station format.
01:51In our case, it's at the 100 position.
01:56This just makes the station values more readable.
02:02Now that we've decided on our labeling, we'll want to apply these same labels to other alignments.
02:08We can do this by saving the labels as a label set.
02:14Rename the label set to design labels and save it.
02:20We'll label the other alignments in our model by applying our new label set to them.
02:27Edit the alignment labels and import the label set and click OK to apply.
02:35You can see how having these styles predefined in a template could save time when creating
02:41your models.
02:44We're now going to add a different type of alignment label.
02:48These labels are more general labels which can reference information from an alignment.
02:55Select the alignment and from the contextual ribbon, choose Add Labels then Add Alignment Labels.
03:06First set the label type to Station Offset Fixed Point then change the style to Station Offset.
03:15This will label the fixed position with the Station Offset of the alignment.
03:20The Marker style will set the style of the marker for the point being labeled.
03:27Click Add, select the alignment to use as a reference, then pick the point to be labeled.
03:34You can see the Station Offset is labeled based on the reference alignment.
03:40Now change the label type to Station Offset and set the style to Station Offset.
03:47This will also label a Station Offset from the alignment, but the label will remember its
03:52values and will move when the alignment changes.
03:56When adding this label, you select the Station and Offset separately.
04:02When I move the alignment, the Station positions change as the curve is being stretched.
04:10The Fixed Point labels stay in position, but their values change, whereas the Station Offset
04:17label moves to stay at its assigned Station and Offset.
04:24Now we will label the segments of the alignment.
04:27Choose the label type, Multiple Segments.
04:31Using this we can label all the lines, curves and spirals on the alignment in one go.
04:39The Table Tag Numbering will be used later to create a table of the alignment segments.
04:46Add these labels to the alignment.
04:49You can see that it is labeled each segment with information relating to the type of segment.
04:56These labels are linked to the alignment and can be adjusted by using the grips.
05:03To create an alignment table in the drawing, select the alignment and from the ribbon choose
05:08Add Tables.
05:12We can add tables for each segment type or we can add all the segments in one table.
05:19Choose Add Segments.
05:22When we add the table, we can choose an entire alignment or we can pick the segment labels
05:27that we want to add to the table.
05:30We must have created segment labels on the alignment first before we can create a table.
05:38Civil 3D will convert the labels to tags and add the segment information to the table.
05:46There are settings to control how many rows are placed in the table and how multiple tables
05:51are laid out if the number of rows exceeds the maximum.
05:55The default behavior for the table is dynamic which means it will update if the alignment
06:00is edited.
06:02Click OK and select a location in the drawing for the table.
06:07We can see here how the labels we have added have been converted to numbered tags which are
06:12referenced in the table.
