Edge of pavement whiskers

[dbanaszak]

We use four diagonal lines, then skip two, then four more, and repeat, to delineate the edge of existing asphalt pavement. Currently the company uses a line type to do this, but it only works for straight sections of roadway. Using the MEASURE command to place individual diagonal lines gives the desired effect on curves, but then I have to go back and remove two lines after every four, which can be time consuming. Creating a block of four diagonal lines and using the MEASURE command still looks like crud on curves. Does anybody have a better solution?

Try using an ARRAYPATH for replicating the whiskers along the linework.  The array will stay linked to the line as its path and follow any new edits to the line.

I like the functionality, never having used the command before, but I still need to get the 4-2-4 spacing to make it functional. Thanx

in 2025, there is the new Hatch path functionality, is there a way you could make a hatch pattern that fits the pattern you need, and then apply it along the edge of the pavement?

A dimensioned picture of what you want would help.

I might not understand, but I think a complex linetype would do what you want.

*Edge Pvmt 1,_////__////__////_
A,.1,["/",simplex,S=0.1,R=0.0,X=-.085,Y=-.119],.067,
["/",simplex,S=0.1,R=0.0,X=-.085,Y=-.119],.067,
["/",simplex,S=0.1,R=0.0,X=-.085,Y=-.119],.067,
["/",simplex,S=0.1,R=0.0,X=-.085,Y=-.119],.1

*Edge Pvmt 2,_\\\\__\\\\__\\\\_
A,.1,["\",simplex,S=0.1,R=0.0,X=-.085,Y=.033],.067,

["\",simplex,S=0.1,R=0.0,X=-.085,Y=.033],.067,

["\",simplex,S=0.1,R=0.0,X=-.085,Y=.033],.067,

["\",simplex,S=0.1,R=0.0,X=-.085,Y=.033],.1

Note the line definition (Italics) is all on one line.

EDIT 2024-10-22 Be sure that the polyline misc property "Linetype generation" is set to enabled.

EDIT 2024-10-24 Changed Lintype name to "Edge Pvmt 1" and added definition for "Edge Pvmt 2."

                                      Note: Style "simplex" is required. 

Edit 2024-10-24:
It seems that arcs are not reversable, so you might need a "\" version for arcs.  

Lines, polylines*, and Civil 3D feature lines are directional. Chose the appropriate linetype. 
Regardless of the direction that they are initially drawn, Arcs are rendered counterclockwise and are not reversible.

Circle act like arcs.

*Polylines with linetype generation enabled, and Civil 3D feature lines, are rendered in the direction drawn, with arcs behaving as expected. Polylines with linetype generation disabled have lines rendered in the direction drawn, and arcs rendered counterclockwise, with sometimes unexpected behavior. 

A drawing file and .lin file are attached.
Here is a sample:

I hope this helps.

That looks marvelous. Thanx

Modified my ACAD.LIN file and started trying out the new linetype. It works great on lines, it even REVERSEs. CIRCLEs, ARCs, and PLINEs not so much, as can be seen in the attached file. It only seems to work on the convex side of them. I'm not sure what's causing this based on looking at your examples. Any suggestions?

D'OH!

Make sure that the polyline misc property "Linetype generation" is set to enabled.
I should have mentioned this in the original reply. I will edit it to add a note.

My initial reply (post 8) addresses the directional problem for polyline arcs.

After re-reading your post, I see that I did not address Circles and Arcs.

I did address this in post 5: "It seems that arcs are not reversable, so you might need a "\" version for arcs."

Please see post 5, which I have edited post 5 to include this secondary linetype.

ENABLE linetypes was all I needed to be satisfied. Thanx

You are welcome, @dbanaszak.

I think that the extra information gives a complete picture of the solution that might be useful to other users, now or in the future.
