00:09This profile is a long section view of a surface, in our case the existing ground, generated along the length
00:16of an alignment.
00:18The profile is drawing a profile view, which is required to be able to view the profile in the drawing.
00:25The surface profile samples the surface elevations along its length.
00:31You can think of the profile view as a special viewport, which allows us to design our road elevations in
00:38a long section.
00:43We're now going to create a surface profile for the McAllister Boulevard alignment.
00:48Select the alignment and on the contextual ribbon choose surface profile.
00:53The alignment setting shows we're sampling along the McAllister Boulevard alignment.
00:58You can set the station range for the sampled surface.
01:03Under select surfaces you'll see a list of surfaces in your model.
01:07You can select a surface from the draw ring using this button or you can select it in the list.
01:13Select the existing ground surface and click Add.
01:17The surface is sampled and a surface profile created and it's added to the list of profiles for the alignment.
01:25You can view information about the profile here.
01:29Notice it has been assigned a default style of existing ground profile.
01:35Select Draw in Profile View to create a profile view to display the surface profile.
01:43In the Create Profile View dialog make sure you're using the McAllister Boulevard alignment.
01:50The profile view will be given its own name.
01:53The automatic name format will call this McAllister Boulevard and the next number.
02:00The profile view has a style.
02:02We're using major grids and horizontal geometry points.
02:06You can see a preview of available styles using this button.
02:15If you have offset profiles, for example a left and right road channel, then you can draw these as stacked
02:22profiles.
02:24Click Next.
02:26The Station Range is derived from the alignment length automatically.
02:30You can select User Specified Range if you want to change it.
02:35The Profile View Height is derived from the heights on the sampled surface.
02:41Again, you can specify different values if you wish.
02:46If your profiles cover a wide range of elevations, then you can split the view at different locations and specify
02:53a datum for each section.
03:01The profile display options show what's going to be drawn in the view.
03:06The update mode is dynamic and so the profile will update automatically.
03:12You can change the profile style and apply labels to the profile.
03:23Data bands can be added to the view.
03:26We're using the default band set EGFG Elevations and Stations.
03:32You can import a different set of bands and you can see a preview of the band set here.
03:39This band set is drawn at the bottom of the profile view and contains a single data band that will
03:45show stations and elevations.
03:49If we had more than one profile in our view, then we could apply hatching to the areas between the
03:54profiles.
03:56This is used to denote areas of cut and fill between an existing ground profile and a designed profile.
04:04Click Create Profile View.
04:08In the drawing, zoom out and pick a point to the right of the site.
04:12This will place the profile view in the drawing.
04:18Zoom into the profile view.
04:21You can see the red dotted line that represents the ground profile.
04:26The profile view style we've chosen is exaggerated vertically.
04:32We can change the vertical exaggeration factor by editing the style.
04:39If you select the view, right click and choose Edit Profile View Style.
04:44On the Graph tab, we can set a new vertical exaggeration.
04:49Try setting it to 5 to see the result.
04:54So we can see the alignment and the profile in the same window.
04:58On the View Ribbon, click on Viewport Configuration and choose To Horizontal.
05:09In the bottom viewport, zoom into the profile view.
05:14And in the top viewport, zoom into the alignment in Plan.
05:20Go to the Analyse Ribbon and on the right hand side under Enquiry, choose Station Tracker.
05:27Select it for all viewports.
05:31Now when we move the cursor in the Plan view, there's a tracking line showing the location in the profile
05:37view.
05:39Similarly, if I do the same in the profile view, the tracking line tracks in the Plan view.
05:46Restore the single viewport.
05:50We're now going to create profile views for the remaining alignments.
05:55Select the Sycamore Heights alignment and on the Ribbon choose Surface Profile.
06:00Select the existing ground surface and choose Add.
06:04Go straight to Draw in Profile View.
06:07In the Profile View dialog, choose Create Profile View to create a new view with the default settings.
06:14Pick a point underneath the previous profile view to add it to the drawing.
06:20Do the same for Woodside View.
06:31To reposition a view, select it and use a single grip to move the view to a new location.
06:37In Prospector, you can manage your profiles and profile views.
06:42Expand the Alignments collection and expand Centre Line Alignments.
06:46All our alignments are organised in this subfolder.
06:51Expand Macaulister Boulevard, then expand Profiles.
06:55Here you'll see the existing ground surface profile.
07:00Expand Profile View and you'll see the profile view you created.
07:05You can zoom to a view from here.
07:08Now that you have created profiles of the existing ground surface along your Centre Line Alignments
07:13and have drawn them in profile views, you can plan.
07:16The Design Criteria file generally comes as part of a country kit that can be installed in Civil 3D.
07:23It's not stored in the drawing and is often saved to a server,
07:26so the entire project team can access it.
07:29In this example, which is the US AASHTO standard,
07:33we can see Profile Design Criteria in the form of minimum k-values.
07:39And it's defined for different road speeds with different definitions,
07:43stopping, passing and headlight sight distances.
07:50In this video, we are going to focus on defining design checks that are saved in the drawing template.
07:57There will be local standards or national standards that you can follow
08:00to determine the relevant criteria to apply to your own design checks.
08:06We'll be defining minimum and maximum grades and minimum k-values.
08:12A k-value is the ratio between the curve length and the changing grade of its tangents.
08:18More information on this can be found in the Civil 3D help file.
08:23In this drawing, we have created design profiles for a collector road,
08:28McAllister Boulevard, and for a subdivision road, Sycamore Heights.
08:33The design profiles have been deliberately drawn with exaggerated elevations
08:39so we can show the effect of adding design checks to them.
08:43Now we'll create some profile design checks that we can apply to the profiles in the drawing.
08:50In the Civil 3D tool space, click on the Settings tab, expand Profile, and then Design Checks.
08:59We can create individual checks for our lines and curves,
09:03and then we group these together in a check set, which we can apply to a profile.
09:08We're going to create a check set for our collector road, McAllister Boulevard,
09:13and one for our residential subdivision roads.
09:17In the Settings tab, under Design Checks, click on Line, right click and choose New.
09:26Change the name to Min Grade 0.5%.
09:31The name is important as this is shown on the Warning Symbol tooltip to notify you which check has failed.
09:39This design check will test whether our tangent gradient is at least plus or minus 0.5%.
09:46We don't want grades flatter than this because our road won't drain properly.
09:51For the expression, we're first going to choose a function, Abs.
09:56This will give us a positive number whether our gradient is positive or negative.
10:02In the Properties, you'll see a list of properties for the profile that we can use in our checks.
10:08Select Tangent Grade.
10:10In the expression, add a closing bracket, then pick or type greater than or equal to and then type 0
10:18.005.
10:21This tells Civil 3D that the gradient of our tangents must be greater than or equal to 0.5%.
10:28Click OK to save the Design Check.
10:33Now add another line check.
10:35For the name, type MaxGrade 15%.
10:39This check will show a warning if the grade is greater than 15%.
10:47Add the function Abs again.
10:52Then select Tangent Grade.
10:56Add a closing bracket, then type or pick less than or equal to and then type 0.15.
11:04Click OK to save this Design Check.
11:09Now we'll add our curve checks.
11:11Click on Curve, right click and choose New.
11:16Change the name to Subdivision Min K 19.
11:22We're going to specify that the minimum K value for the curve must not be less than 19.
11:28In the expression, add the property K value, then choose greater than or equal to and then 19.
11:37Click OK.
11:42Add another curve check.
11:44Add another curve check.
11:44This one is for our Collector Road, so name this one Collector Min K 115.
11:52The Collector Road is a higher speed road and requires longer vertical curves.
11:57For the expression, add the K value, then greater than or equal to and then 115 and click OK.
12:10Now that we've created our design checks, we can add them to some check sets.
12:16Click on Design Check Sets, right click and choose New.
12:22This check set will be applied to our lower speed residential roads, so on the Information tab rename this one
12:28Subdivision.
12:31On the Design Checks tab, we can add our individual line or curve checks to the check set.
12:37For Type Line, add Max Grade 15% and add Min Grade 0.5%.
12:47Change the type to Curve and add the Subdivision Min K 19 check.
12:56When we add a curve check, we can specify whether it should apply to crest, sag or crest and sag
13:02curves.
13:03This one will be for both.
13:06Click OK to save the check set.
13:11Now create a new check set.
13:13Now create a new check set.
13:13This one will be for our higher speed Collector Road, so name it Collector.
13:23For the Type Line, add the Max Grade and Min Grade checks.
13:31Change the type to Curve and add the Curve check, Collector Min K 115 check.
13:40And save the check set.
13:44To add the check set to the Collector Profile, click on the McAllister Boulevard Design Profile,
13:51right click and open the Profile Properties.
13:56On the Design Criteria tab, make sure Use Criteria Based Design and Use Design Check Set are both selected.
14:06Set the check set to Collector and then click OK.
14:11You'll see warnings are now displayed on the Profile.
14:16Repeat this process to add the Subdivision Check Set to our designed Subdivision Road Sycamore Heights.
14:32Review the warnings in your model.
14:36When you hover over a warning, a tooltip displays the name of the design check that was violated.
14:43This one shows the grade is too shallow.
14:45We'd need to increase the gradient of this tangent to meet our standards and remove the warning.
14:51This one for our curve shows that the curve is clearly too short for the changing gradient.
14:56We must increase the length of this curve significantly.
14:59We 유 sucked the length of this capacity significantly.
15:00This one shows the length of the path the mid- crescent point unions can use your �urus navigational
