I am still in the stages of playing with Corridors and making one corridor mutliple times.  So, here is where are here in our office.  The higher up people choose to have two seperate reports and at time more then two reports depending on the subgrade material.  We typically do two report which are Existing to Propose > finish to finish report. simple right.  The second report Exisinting to Propose > finish to subgrade. A bit more instruction added to the corridor. Other times we have roadways that have different typical sections with various subgrade depths and different material.  What we have done is do the project as Save As, so we could make changes to the subgrade and run report without losing our other corridor data.

My thoughts and request to saving time to coping a corrdiro

After seeing the save templates, this could be some help making another corridor in the same project.  Just need to put this to the test. ** Would this be a method to copy a whole corridor and create a copy to start the subgrade corrdiors??

Is there a way to copy a corridor without using the surface as a instruction in a new corridor and not saving each template?  

I have just tried the save template. In the same project i started a new corridor for the subgrade. I used the same data to start the corridor> alignment, existing ground, reference lines. I start my first template> same first station and as i import the first template I get an error (image below) what am i missing?

update:  thought came to me that the node is a beginning node in the template.  As I did not start the template with a node rather with a surface.  The template would not be recognized.  Since then I dropped in a first instruction with a node that is not part of the finish material.  ** other issues came up.  As read in in other post,  Alan mentioned about importing templated with tables, surfaces, and connect instruction.  I have surfaces and connect instruction in each template I want to import.  So I am back to the drawing board on copying a corridor.  Rather not have to do a save as. 

You can always do the following

1) Create a second Corridor, use the same HAL and VAL as the first corridor, use the same Existing Ground as the first corridor

2) For the Template use the Copy Template option and that brings across the Template from Corridor 1 into the new corridor and creates the exact same information. You can now edit that template to add the Subgrades to it etc and keep it separate to the first corridor. 

If you use a Copy Template where the instruction is a Surface Instruction you are right to say that the Surface Instruction does not seem to work when you use a Copy Template - I am not sure why that is and I have to ask development on that - that appears to be a "defect" in the system. We don't allow one corridor to use another corridors surface model because they are both dependent objects - you can reference one in the other but not use the surface of one corridor in another corridor without first exploding it and making it into a surface model

I am not sure why we cannot create a Copy of a Corridor either - I had never tried that before now - I will ask why that is

You can select the Corridor and the Corridor Surface and Export it to VCL and then I would rename the Original Corridor and Original Corridor Surface in the Project and then reimport the VCL - this will create a copy of the Corridor and Templates and Surface with same name as the original Corridor - this saves you having to create a Save As and separate project. Maybe this is the answer you were looking for?

I tried the VCL and no luck, error message at export.   I am attaching my project for your touch.  I have a few linestrings reference and used in the corridor.  I have a left and right PGL based off my center alignment,  so i decided to just do linestring for my all curb lines and build my surface.  There are some setting that I am just getting around to using and still working on getting better at making a presentable corridor.  so my Corridor is based off surfaces, tables, connect instructions. Hope you can be of some assistance.  which you always are. 

I tried also and got the same error that you saw - have forwarded to Trimble Development for comment

Alan

Glad you fowarded this issue.  This will be so very much useful, using the save template to or even better have a copy corridor tool/command.   

OK - so we have been looking at your data. We are not sure how you achieved this but one of the Nodes in the Node List (the last one) was Unknown - typically we set Blank ones to Undefined, however in this case there is a Blank Node Name that is "Unknown" in the Name field - so we were not picking that up. If you change it in the Node list to eg XX then export the VCL flle for the corridor it appears to export OK from TBC 5.3 (due out soon), however the fix we added to ignore Blank Fields as a result of getting your file needs 5.3 to solve the issue. If we then import the file, it has another issue that the developers are looking at now. So hopefully we will have a fix that allows this corridor to Export and then Import with no issue.

With the Copy Template - it does seem to work OK, however I did notice that when the instruction is a Surface Instruction, in the copy template version, the surface instruction has Lateral Extents applied for some reason which is wrong on our side and I reported that in to be addressed - but if I turn that off it works OK

On the other discussion we had earlier. If you build eg Finished Grade Model in one Corridor and that generates a Finished Grade Corridor Surface. You can create a second corridor and add a surface instruction that uses the first corridor surface as Finished Grade or you can move it vertically and limit it laterally to use it as a Subgrade surface. If you do that I would recommend changing the properties of the First Corridor Surface to Rebuild by User so that it doesnt change once it has been used in the second corridor.

I found the Node Name List and changed the "unknown" to XZY. as seen below.  I still get an error message when exporting.  Here are the steps I use to export corridor.  > project explorer >click and highlight corridor name >export >choose folder to save in and click export. Then message pops up. What steps am I missing 

I decided on exporting the Corridor Surface as an XML ( Surface Description - Triangles) which as long as I have linework for road and slopes it make building the subgrade so much faster.  We may have to start a post with everyones shortcuts to corridors.   The one thing I do not like about using surfaces as instructions is that the surface when interpolated in the corridor triangles do not match the orignal surface. example is in the same project thats in your hands.  Surface is country extension roadway used in the corridor as a instruction.  

One thing that has come up is on the icon for the corridor surface.  Icon has a red box. What is the meaning behind this

It is one of the following

1) If you have the Rebuild Method for the Surface set to By User, you will

get a Red Flag on the Surface to say that it needs to be recomputed in the

event that you have made a change to the corridor model that is not

reflected in the COrridor Surface because you have to rebuiod it By User

(yourself rather than automatic) (Typically used on big jobs that take time

to recompute

2) There is an issue with the Corridor Model of some kind - it could be

that your alignment has deflections in it and the corridor is set to

Alignment Based and cannot compute that way because of the deflections. It

could be that you have elements of the alignment that arent right - I see

some with 0 length or very short segments or segments that overlap or go

backwards and then forwards again (can happen when you use CAD lines to

create an Alignment). But typically the corridor is not happy about

something so it flags Red and you have to take a look to find out what is

wrong - I would have to see the data to determine that - no way to tell

otherwise - I have a mental check list of things to look at when I see the

Red dot on the model.

I came across somtehing help on the topic of exporting a corridor VCL.  I export a Corridor surface only as a VCL ( just the surface).  As I was going to use the surface as a reference in another project.  TBC should did a smart export.  The VCL for the surface brought over the corridor and all line work involved in the corridor.  I tried this with a corridor that I used a surface as one of the instruction and that would not export. 

 Just exporting the VCL surface one click and export was great.  I will think it over the weekend and see if I am ready to move onto v5.30.  hopefully this was fixed in v5.30.
