Thought some of you may enjoy this tip.. We all use gradings – sometimes our feature lines have curves. We want to move them, but the problem is they don’t stay tangential… Here is a quick fix that doesn’t involve exploding the gradings/feature lines. On the modify ribbon or featureline context ribbon select the “edit curves” button.. (by the way there are plenty of awesome commands on here you should know as well.. have a browse!)
Select a curve – then press the “maintain tangency” button
Fixed! Plus the grading updates!
If you get an error.. move the line a little bit and try again! “It unfortunately doesn’t maintain tangency when you move it again.. but still better than exploding and starting again..
Would it not be nice to match properties between profile/section views and have it create all the same profiles/hatching styles/band styles etc in the target profile view in one click..
New upgrades to the beta.autodesk.com site saw not really a lot change.
It is really difficult to see what requests/issues are posted as there are no descriptions next to the FR DE codes
The editor is does not easily allow one to add inline images to describe what you are talking about. You can only “attach files” which is a very “old skool” way of posting problems an ideas.
If you want genuine contribution from the community get some better technology in place!
Currently the elevation and width targets override using “absolute” elevation or width.
The following changes would add enhanced flexibility to control key parameters in a corridor design.
This allows the user to define delta y/delta x/slope using a profile height.
It removes having to code this as an expression.
It also allows the custom subassembly to display correctly in layout mode.
So for example:
A profile with a elevation of 0.5 would make the slope of a link 0.5%
A profile with an elevation of 1.5 would make a pipe dia in a custom subassembly equal 1.5m dia.
A profile with a elevation of 1.2 would make the relative height of a wall 1.2m.
A offset target/profile with a width from cl/height of 3m would change the relative width to 3m
So rather than constantly having to try and find the correct elevation on the main profile. You can control parameters on a separate profile above/below the main profile. Similar to the Super elevation profile view.
UPDATE: New Corridor Transitions in Civil 3D 2023 and beyond have somewhat solved this problem.. Although with some bugs..
You can’t really transition in a way that is simple, like 12d, LDT, MX etc.
You can change the slope easily, but not transition easily! I.E Cubic, Linear transition etc.
A few methods you can use include the following.
Use the Superelevation editor??
Click on the subassembly that you want to transition (The Daylight) and select a super elevation mode say “Left Outside Lane”.
Then select your corridor and add a superelevation view
Then go through the cumbersome tabular editor to populatd the grades on the graph.Should look like so.
The finished results looks a little like so, which is somewhat alright, but still not nice, as the transition is linear. And we get jagged edges on the contours.
Use the Override Stations Method.
Select the corridor and go to the section editor
Select the Parameters Editor and modify the grade.
Then apply to the station range I want.
Still only gets me halfway there, as there is no transition options!!, the only way to force the transition from here is to change the sampling on the corridor reducing the quality of the transition anyway!
Do It manually by working out the location on the surface you need to widen to. But that is just not realistic!
Use a fixed link and link the grade in the fixed link to the daylight link. Also horribly cumbersome, but gets the best result.
Draw a Profile that represent grade so (elevation of 0.4 = 40% etc.)
Add a link with elevation target to your assembly like vertical elevation. Make sure it is added before your daylight link or this wont work
Next Select your Assembly go to its properties and select the construction tab, you need to link your daylights slope to your fake links elevation
Finally target the elevation profile with your new elevation link and watch the magic happen.
Looks the best, and it is dynamic, but extremely infuriating to setup.
UPDATE: *.12daz files are just zip files. Rename it to <YOURFILE>.zip and extract the *.12da file within
If anyone has been trying to use the 12DA import extension for Civil 3D and it isn’t working. Read on!
I have been having problems importing latest 12DA files. It doesn’t import anything for some reason.
A simple change to the 12DA files encoding fixes the error. Get NOTEPAD ++ Download Here
Old 12DA files encoded with “UTF-8 without BOM” will work. However new ones encoded with “UCS-2 Little Endian” won’t convert them and save as shown below. All working again!
Extra Bonus (courtesy lem_1020)
“Saved this way it actually allows you to open new version 12da projects in old 12d model versions also.”
