Short description
🎛️ AutoCAD VPLAYER batch override tool for applying viewport layer overrides across selected layouts.

Command:
LayoutVPOverrides
Description:
🎛️ LayoutVPOverrides is an AutoLISP / Visual LISP utility for applying AutoCAD viewport layer overrides across multiple selected layouts.
🧭 It guides the user through DCL selection lists for layer groups, layers, override property, property value, and target layouts.
📐 The command is especially useful in Civil 3D sheet sets where xref layers need consistent viewport-specific Freeze, Thaw, Color, Linetype, Lineweight, Plot Style, or Transparency settings across many layouts.
🧩 It builds a VPLAYER command sequence and applies it layout-by-layout while restoring the active layout afterward.
Helper function: (if any)
:layoutlistordered returns layouts in tab order.
:xreflistordered lists xref block names for layer-group filtering.
:layerlistordered lists drawing layers alphabetically.
:linetypelistordered lists loaded linetypes.
:plotstylelistordered reads available plot style table names from the active layout.
:truecolor-split-str converts AutoCAD TrueColor values into RGB text for VPLAYER input.
:DclList creates reusable temporary DCL selection lists with single or multiple selection.
Functionalities:
🧩 Filter layer targets by All layers, Non-Xref Layers, Last group, or selected xref layer groups.
📑 Select one or many layers for viewport override operations.
🎛️ Apply VPLAYER properties: Freeze, Thaw, Color, Ltype, LWeight, PStyle, and Transparency.
🧹 Remove viewport overrides for All, Color, Ltype, LWeight, PStyle, or Transparency.
🎨 Pick ACI or TrueColor values using AutoCAD color dialog.
📐 Apply changes across All layouts, Last group, or selected layouts.
↩️ Wrap processing in an undo mark and restore the previously active CTAB.
Result:
✅ Faster viewport override standardization across sheet sets.
✅ More consistent xref layer visibility and plotted appearance in multiple layout tabs.
✅ Reduced repetitive use of VPLAYER on each layout.
✅ Better control of viewport-specific layer freeze/thaw, color, linetype, lineweight, plot style, and transparency settings.
