section label does not flip along with section

[ktangBNSUP]

Hi Everyone,

My section labels look correct in the default view direction (bottom view), but they appear mirrored when I flip the views (top view). See sample file and snapshot

I’ve tried adjusting parameters such as plan readability and rotation angle, but neither solves the problem. Ideally, I’d like to mirror the labels along with the sections in a batch.

The attached snapshots show both the flipped and default sections as examples. I’ve also included a sample file with a few sections. In the sample, I can manually realign the labels, but in real projects with hundreds of sections, that becomes a hassle.

I do know a workaround where flipping the alignment avoids label issues, but that causes problems when exporting to HEC-RAS, especially with stationing adjustments.

Does anyone know a trick to flip the labels in batch along with the sections?

Thanks for the CAD file...

We're talking here about treating your file with normal plain AutoCAD.

• I found in your CAD drawing 1499 ACAD-PROXY-ENTITY. It means that the file was created in vertical Autodesk products (like AutoCAD Architecture, Civil 3D, Plant 3D, etc.) or 3rd-party applications.
• So,I have to use  -EXPORTTOAUTOCAD command to convert them to normal AutoCAD entities.
• Click on below image to see how by exploding those blocks you can mirror all of your elements normal and without any problems.
• Always try to get a FULL clean drawing to avoid yourself any surprises that you don't need.

Hope that helps you ..

Here is a snapshot, circled the labels that look funny

Thanks. But what I need is a civil 3D solution.

If I convert them to normal AutoCAD, not to mention I need to flip them one by one (for hundreds of section in some of my projects), but also that would break the dynamic link, meaning if I get any changes in the model, that would not be reflected in the section view.

Apparently the label style isn't very good at adapting to reversed section views.  Its getting the text angle wrong.  We can add a couple components to the label style to help it get it right.

First add a line component with its start anchored tot he start of the segment and its end anchored to the end of the segment.  This will give us a component to anchor to that will have the correct angle (even in reversed section views).  We don't need to see this line in the label so set its visibility setting to false.  The downside to using this as an anchor component is that it changes direction when its on the left or right side of the section view. Directions relative to the line become flipped, up is down and down is up.  To get around that we can add a new text component to the style, anchor it's center/middle to the middle of the line and use it's top center as the anchor for the Slope text's bottom middle.  Again we don't need to see this new text component in the label so we can set its visibility to false.  Its only purpose is to provide a consistent anchor object for the Slope text as this text object will auto-flip to read right side up and have consistent anchor locations when its on either side of the section view. This new text component will also pass on its angle that it gets from the line component to the Slope text.

That is genius. I don't quite understand the text just yet, but I will study your file. Thanks a lot.
