How to Change the status of superimposed profile from Dynamic to static

[nkiakas]

Hello

I would like to change the status of a superimposed profile from dynamic to static.

I am trying the same way like changing the offset profile status from dynamic to static but the dropdown list is inactive.

Did anyone face this before?

Why i should do this? Because i want to create an offset alignment+profile and profile can't be created from the source profile (the superimposed profile)

Thank you

Hi @nkiakas, you can make it static, but you must do that in the source profile. Go to the profile view, where you have the profile you superimposed somewhere else. Select the profile, go to the properties window, and open the profile data tab. There, you can select the preferred mode in the Update Mode Column.

If the superimposed profile comes from an offset alignment where you automatically created a profile when you got the offset alignment, then draw the profile view. You'll be able to select the profile, go to properties, and update the mode. In the following image, you can see an example of this case. The icon I point at with the red arrow indicates this profile was created from an offset alignment.

I hope this helps. Best regards!

Hi @ecfernandez 

Thanks for your reply

The source profile is not an offset profile. Its a normal profile created manually by me.

In the properties window of the source profile i don't have the option to do anything...

I have to note that I am working on trial version of 2025

Hi @nkiakas, thanks for your reply and for the screenshot. From the image I could see that your profile is a layout profile (design profile). That's why you cannot update the mode in which the profile updates. Look at the following image; it is from a layout profile, too.

 The update mode gets activated for profiles of another type, like surface profiles or offset profiles, as I was discussing in the previous post. Your beta version of Civil 3D software is not the problem.

Layout profiles can be configured to update when you change the horizontal alignment. However, those automatic updates made by Civil 3D are not always good when your changes in the horizontal alignment are radical. You can activate that here in the same properties window but in the "profile locking" tab:

If you make minor changes to your horizontal alignment, go ahead and activate it. Otherwise, I would advise going for the option "anchor profile to alignment start," which keeps the profile unchanged, and then I can go and edit what I need and how I want it to be edited.

 I hope this helps. Best regards!

Hi @ecfernandez

My screenshot from my previous reply yes its a layout profile. Lets say its the profile A from Alignment A.

I created an alignment, alignment B, "running" almost parallel to alignment A, but not offset to alignment A.

Then i created the profile B, by superimposing the profile A from alignment A, to the profile view of alignment B.

I want to make the profile B static, because from Alignment B, i want to produce more offset alignment(s) and profile(s). Because profile B is dynamic ,i don't have the option to produce offset profile(s) from alignment B. I can produce only offset alignment(s).

The attached snapshot is from profile B

Thanks

Hi @nkiakas, I think that so far, there are several things we can clarify:

1. You cannot change the "update mode" of a superimposed profile directly in the profile view where you superimposed it. You must change that behavior in the source profile, which leads us to clarification 2.

2. You can change the "update mode" for surface profiles and automatically-created offset profiles, not Layout Profiles. (see the following image)

Offset profile (you can change the update mode)

Surface profile (you can change the update mode)

Based on your example of Alignment A and Alignment B, in which both alignments have a profile view and a profile you are superimposing from A to B, I would say the following.

1. If the profile you created for Alignment A and later superimposed to Alignment B's profile view is a surface profile or an offset profile, do not try to change the "update mode" in Alignment B's profile view. This option will appear grayed as you showed in your screenshot. Instead, go to Alignment A's profile view, select the source profile, open the properties window, and change the "update mode" from dynamic to static.

2. If the profile you created for Alignment A and later superimposed to Alignment B's profile view is a layout profile, you won't be able to change the "update mode." You must rely on the "profile locking" options I mentioned in the second post.

I hope this helps. Best regards!

Hi @ecfernandez

Unfortunately i am in option 2.

You are right. Its not possible to change the status from dynamic to static in a superimposed profile.

I did it with a divert and little bit "stupid" way.

Exported my profile to ASCII file and reimported.

I never did this before and i had doubts for the geometry of the new imported profile (was afraid that maybe for millimeters in stations/elevations/curves will differ).

I compared the 2 profiles by adding a band for elevation differences (with 4 decimal digits) and both was exactly the same.

I will try to make this command more "tidy" by writing some code in .NET or to study if this can be possible with a dynamo script.

Anyway thanks a lot
