PROFILE FROM POLYLINE

[cpusey]

I have a bunch of profiles with the finished grade shown with a polyline. I have to generate roadway corridors from these profiles (done by others) I am able to put there polylines in my profiles correctly and would like to convert the polyline to the finish grade proflie without having to click on every vertex. Can this be done?

In 2010 you can explode the polyline and add then add the individual lines to the design profile uinsg the "Convert AutoCAD Line and Spline" command. The only thing that starts to get tricky is the arcs/splines. I would just use the tangents and add any curves after the fact.

sounds like you might try converting that polyline into a comma delimited TXT file that contains STA, Elevation, (Vertical Curve Optional), then use create profile from file, and import the TXT file to draw your FG profiles in the profile view grid.

Thanks to both of you.

Spoken like a Map expert... 🙂

I actually don't know how you would manage that... converting the polyline into a Sta/Elev report would be tricky.

I'm partial to this solution myself. Just position the polyline on the profile view, then select it. Instant Profile. Well, as long as there are no vertical curves, anyway.

If the OP knew the vertical scale exaggeration, one
could create an alignment along the profile datum line, create an empty
profile view over the alignment with the grid aligned to the dumb profile.
You can now either digitize on-screen or label the profile view to help create
the sta/elev file.

But if you're going to do all that, it would be much faster to just draw the whole Profile directly by picking each vertex, and forget about trying to create a Sta/Elev dump...

This is something obvious that Civil3d and LDD has never picked up on. You have to jump through hoops to do it but it can be done.

Hi

You can use this simple program! Type "NETLOAD" in command bar and load this DLL and type "PFP" in coammand bar and then select your polyline then select your Profile View. Of course your polyline must be in your ProfileView. If you have problem in netload or loading this dll, you must copy and paste or replace with second file ("acad.exe.config") and right click on ProfileToolBox.dll and go to properties and UNBLOCK this dll file.

Good Luck

Hi this is what I got when I tried to load the dll:

"Command: NETLOAD
Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\txiao\Downloads\DLL\ProfileToolBox.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

then "PFP" won't work, can someone help me?

Thanks

Just right click on DLL file and select properties and click on Unblock button and then run this dll again with netload command.

Hi

Thank you for sharing this tool. Sadly, it wasn't working for me, so I decompiled it and tried to fix the code. Which actually worked. I now have a working version for C3D 2019. See here.

I attach VS codes, You can share it with others

Hi, thank you for sharing this source code.

But, as I outlined in my reverse engineering project found here, there are a couple of deficiencies in your code. In particular:

//Original
Profile oProfile = trans.GetObject(oProfileId, OpenMode.ForRead) as Profile;
//Should be
Profile oProfile = trans.GetObject(oProfileId, OpenMode.ForWrite) as Profile;

//Original
Point2d po = arcseg.GetSamplePoints(10)[6];
//Should be
Point2d po = arcseg.GetSamplePoints(11)[6];

[MGO-Norsyn]

Ooops, in the previous post, the point selection arguments should be (11)[5]

Thanks for posting.  I downloaded and ran the command MYPFP.  When prompted to select the polyline, the program returns "Not a polyline".

I'm assuming operator error on my part somewhere in the process.  The polyline consists of only tangent sections (no curves)

Thanks,

Larry

Try converting it to light weight polyline.    (COVERTPOLY)

HI @LK_Indy ,

Did you unlock the DLL file?

For me, it worked perfectly in 2020!
