Issue: Code Set Styles read-only

Corridor and cross section sheet workflows can require significant code set style modification. Copies of WisDOT code set style must be made because the styles are referenced.

Solution:

Move code set styles to the design-start.dwt template. Ability to obtain the latest default styles and reset to default styles can be accomplished with style import tools.

Issue: Profile labels take up too much space and time-consuming to edit

Profile label sets should be improved for production purposes

Solution:

WisDOT Standard label sets improved in the following ways:

Leader lines of Station/Elevation labels shortened
All Station/Elevation point up for readability and space consolidation
Length/K labels aligned to bottom of grid for readability and space consolidation Also, Top Grid label sets have been added. These label sets align grade break and curve Elevation/Offset labels to the top of the profile grid for further space cosolidation and minimizing conflicts with high/low point labels.

Updated Files:

"C:\WisDOT\Stnd\C3D2026\Templates\design-start.dwt"

Issue: Persistent Assembly Label Sizes

The assembly label sizes set with DOTIncreaseAssemblyLabelSizes and DOTDecreaseAssemblyLabelSizes are reset each time the drawing is opened. This is due to the synchronization with the WisDOT reference templates.

Solution:

At drawing startup, restore the last setting for assembly label sizes after synchronizing with the WisDOT reference templates.

Issue: Visibility state of WisDOT Ribbon Tabs

When the visibility of a WisDOT Ribbon Tab is toggled off, it does not stay off for the next Civil 3D session.

Solution:

The WisDOT ribbon tabs are re-loaded at every Civil 3D startup to assure they are kept up-to-date. This forced their visibility to be toggled on for each session. A new bitcode system variable has been introduced to save the visibility state of WisDOT ribbon tabs so they can be restored for the next session. WISTABVISIBILITY

Issue: Map startup performance

Some Civil 3D 2024 drawings with WMS connections crash Civil 3D 2026 when opening. The crash can be prevented by turning off the WMS Layer at drawing open. Once the drawing is opened, the layer can be turned back on. Even if a crash does not occur, the loading of Map layers slow down the drawing open process.

Solution:

Introduce a new system variable DOTMAPLAYERSTARTUP to control how Map layers are loaded at drawing startup.

0 = (Default) Turn off all Map layers at drawing open.
1 = Turn of WisDOT Imagery Layers at drawing open.
>1 = Leave status of Map layers as-is.

Issue: Import Code Set Styles - Select source file

It may be unclear that this command only imports the code set styles that include rendered materials, “Crdr Model - Color by Link - Rendered” and Crdr Model - Color by Top Materials - Rendered”.

Solution:

Update the tool so the source DWG can be chosen by the user, but defaults to C:\WisDOT\Stnd\C3D2026\Components\Assemblies\CodeSets. The tool presents the user with a list of CodeSets that can be imported from the source DWG/DWT.

Issue: Add automated Suffix functionality to all subassemblies

Creating unique names for the point codes is time consuming and lack some options for cinstency.

Solution:

Added a parameter option that will automatically assign a location suffix to the point code from a predefined list of naming options for subassemblies on the right and left of the assembly insertion point, along with an option to create a custom user filled suffix string. Added the use of special symbols to be used to parse and/or overwrite each individual point code.
