This is a very simple and powerful piece. Similarly to a marked point, this piece must come before the other pieces you intend to control with it. Create profile data in a text file, import it as a profile, and control anything. Brilliant.
Talk about thinking outside the box and pulling together so much knowledge to complete such a simple task, yet a task that was not available to users before! This is AMAZING!!
Thank you Drew for the kind words! I wish I could take credit for this workflow but I'm afraid I can't. Peter Funk was kind enough to share this technique with me recently that he learned from his many engagements with Civil 3D users. I thought the idea was brilliant and wanted to pass it along. I like to think of myself as more of a "pizza delivery guy" when it comes to this workflow :)
why someones click dislike it is amazing feature without any additional offsets features on the plan view, you can change width of the assembles and at the and of the day you will get nice and clean plans I use it well and I am happy with this.
Thanks you Jeff, Your videos as always are very informative, I followed your instructions to create transition and widening of Stormwater trench, Thanks you again..
This workflow also can be used for slope and/or grade transitions. Within the Subassembly Composer, create the .pkt with one difference: set the Input/Output Type to Slope or Grade, depending on the purpose of the Number Generator. This works wonderfully for a return side slope condition where my ditch foreslope transitions from 6:1 at the baseline PC, to a 4:1 slope at the baseline PT. Thanks so much Jeff!
Its not actually necessary to change from elevation to slope. To carry out superelevation (slope changes for any reason) using this method, slopes should be in the decimal format. I.e., a slope of 2.5% should be as 0.025. So on the profile you should be at an elevation of 0.025m in metric. Changing from a camber to superelevation where your lane slope is -2.5% to 2.5% you would be going from -0.025m to 0.025m. Should give a grade of 0.5% of the profile. This comment has been repeated for another user
Great Idea!! this idea is very useful to introduce any variable parameter such as width lanes, slopes and heights for walls! THIS IS DEFINITLY, WATCHING OUT OF THE BOX. Thank you !
This is great. I need to widen the dynamic envelope of rail vehicles in curves. I was going to create offset alignments for targets but this is easier and should be reusable in multiple scenarios.
Thank you for the tutorial sir! i'm imagining that we can use this exact technique to make tapered road without using splited region and different assembly, can we?
hello mr.jeff. i think ur viedo is best , ur civil3d,windows,and... is very fast , in other word,ur PC is professinal, please tell ur hardwares for any viedo (in descriptions), specailly ur CPU,GPU,RAM,SSD and M.B model....tank u so much
Jeff, I love your videos, particularly your calm voice as you guide through the instructions. This tip in particular is genius. Unfortunately I have a client who is not allowing custom assemblies on their job. Is there a way to do this without the custom assembly?
Jeff can you point me to a tutorial or create one that show how to transition slopes along a corridor for example we have projects that got from a 2% crown to a full 2% cross slope. I am hoping there is an easier way than the one we currently use to make these adjustments
for some reason at the part where we would have to change the output parameter from 0 in the properties of civil 3d, I'm unable to get there , my properties parameters only show "site-Right" please advise why am i unable to control the output parameter value
Wow Wow such a great art! I did it and worked well, but the output parameter of the subassembly was 0.000 and cant be edited from the property box; why this happened?
Having same issue. Trying to transition gutter from 18" to 24" using this method, but default subassembly output parameter is 0.00 and locked. Have been unable to get this subassembly to function as desired. Any luck finding a solution?
I don't have any value in Parameters on Civil 3D apart from Side. I clearly have an output parameter of 0 in Sub Assembly. But nothing comes up in Civil 3D?! 2019 version 🤔
Hi Jeff, I haven't seen you in about 25 years. I have been at one of your old stopping grounds for about 10 years now where we first met. Back with C3D2016 I made some custom sub-assemblies but the sub-assemblies did not display in the cad file when another user opened the file. Has AutoCAD fixed that? I saved the pkt files to a network location but it was too much of a pain for others to work with so I gave up on the concept.
After civil 3d 2022.1 update, something is wrong with corridors made by this sub. Every link, and every hatch is missing in the corridor. I think that issue is with new targeting system in 2022.1
I love this solution and desperately want to incorporate this into my routine. Unfortunately, I can't seem to get it to work on my end. I've watched your videos numerous times, but things seem to go wrong when I attempt to set the output parameter to something other then zero. When I open my properties the output parameter value of 0.000 is greyed out and it will not allow me to change it. What am I doing wrong???
Jeff, I need assistance with creating a subassembly. I have posted a thread on the Civil 3D forum, but no one has replied. Any assistance you may provide is greatly appreciated.
Hi Jeff, I don't have a lot of colleagues to learn new C3D techniques from, so your tutorials have been priceless. I am trying to use this technique to transition between slopes and grades. For example, if I want to transition between a 2:1 to a 3:1 slope do I set my profile values as 2 and then 3? It looks like for grades decimal fractions are required. For example, a 2% slope needs to be represented as .02 on the profile. Is that correct? Thank you for all your great work!
I know this has been a long time, but for anyone else coming to this video to carry out superelevation using this method, yes slopes should be in the decimal format. I.e., a slope of 2.5% should be as 0.025. So on the profile you should be at an elevation of 0.025m in metric. Changing from a camber to superelevation where your lane slope is -2.5% to 2.5% you would be going from -0.025m to 0.025m. Should give a grade of 0.5% of the profile.
so even though the new profile is a vertical representation, the number generator is calculating the horizontal transition based on the vertical representation. basically getting the numbers only, station and vertical offset and using them both as horizontal numbers. Is this fare to say?
Yes, you are on the right track. The profile is not a vertical representation. It is simply a graphical way to define numeric values along the alignment. The custom subassembly part ("number generator") pulls those numeric values from the profile and then passes them to a subassembly via. an output parameter. Hope this helps!
