Did you mean: 

dynamic copy objects.

dynamic copy objects.

Sometimes, I need some copy of alignments or profiles, but I need that they were dynamic (only in geometry data).

 

Example:

 

I have an alignment called Alignment_1 with calculated superElevations.

I copy / paste this alignment, so I get "Alignment_1_copy".

 

I add or remove superelevation critical stations in Aligment_1_copy, so I retain the original superelevation critical stations in the main alignment.

 

However, if I add or remove an entity in "Alignment_1", then I have to do manually this in "Alignment_1_copy" as well.

 

So, please, I would like objects called "dynamic copy alignment" / "dynamic copy design profile", where we can choose what was dynamic.

 

The copy object will be always in the same location, with the same geometry.

 

In this "dynamic copy alignment",  the "geometry" would be locked.

In general, the copy alignment will be hide (alignment style=hide)

 

It would be useful fore a lot of scenarios, when we can use the copy object and modify some properties of that object, instead of the original object.

I would like to create "dynamic copy object" from  C3D API to use them temporary and finally remove them.

The same in the "Profile" category:  new option: "Dynamic copy Profile".  (about layout profiles).

This way, I can have a pair of Superelevation table using exactly 2 alignments with the same geometry.

I don´t have to import/export superelevation critical stations from Excel files every time in the same alignment..   🙂

 

There are other workarounds using "dynamic copy object"..

Note that I cannot do this with "offset alignment" and offset=0, because Civil 3D doesn´t allow this and throw a report message:

"Value must be bigger than 0"

 

Well, we can put an offset=0.0001, but I would prefer an offset=0.

But you can create an offset alignment at 1m and then offset that one back 1m to the original location. Smiley Happy

jajaja.  🙂

The workaround in Civil 3D is impressive.

I can use the "SuperImpose profile" to project the design profile to another layout profile, but then , this profile is not a design profile.

 

In this case, both alignments are in the same location, so I would like to have exactly the same design profile in antoher profile view (belong to the offset alignment).

Hi @troma

 

I have found out a better way:

Command: AddWidening and we select the main alignment.

Then we remove the Widening in this new offset alignment and this offset alignment is identical as the main alignment (offset=0).

 

Regards.

Cool.

It's rare that I need this, but if it happens again I'll try to remember that!

The utility of this is you have 2 tabledata of SuperelevationCriticalStation, one for each one.

You just must replace the alignment in the Baseline of the corridor. ( I prefer this than import/export criticalSuperelevations file every time)

 

And about dynamic copy profile, it would be this:

 not only for surface profiles but also for layout profiles.

About this:

 

Command: AddWidening and we select the main alignment.

 

 

We have to select the start station and end station of the main alignment, if not, you will get a message in the command line than: without solution.

 

And offset=0.

 

Later, you have to open the properties of this new offset alignment and lock start and end station.

 

 It is certainly strange because we can drag the grip to change the offset but the offset value doesn´t change in the properties form:

I supose that in general, we apply "widening" for offset alignments and this is an exception. (it is a black hole! 🙂 )
