Short description
🧭 ViewportMatchOrientation is an AutoCAD and Civil 3D AutoLISP utility for matching paper space viewport orientation. 🔄 It copies the TwistAngle from one viewport to another so layouts can share the same rotated view direction.
Command:
🚀 Main command: ViewportMatchOrientation
🧭 Select a source viewport, then select a target viewport, and the target receives the source TwistAngle.
Description:
🧭 ViewportMatchOrientation is an SEO-friendly AutoCAD viewport rotation utility for paper space layout coordination.
🔄 The command switches to paper space, prompts for a source viewport, reads its AcDbViewport TwistAngle, then applies that angle to a second selected viewport.
📐 This helps match north orientation, rotated plan views, layout sheet viewports, and Civil 3D plan production view directions.
🎯 The routine is useful when multiple layouts or detail viewports must share the same rotation without manually entering viewport twist values.
Helper function: (if any)
🧩 ssget with Viewport filter selects exactly the source and target viewports.
🧩 vlax-ename->vla-object converts selected viewports to ActiveX objects.
🧩 vla-get-objectname verifies that the selected object is an AcDbViewport.
🧩 vlax-get reads the source TwistAngle property.
🧩 vlax-put-property writes the TwistAngle to the target viewport.
Functionalities:
✅ 🧭 Read viewport orientation from a selected source viewport.
✅ 🔄 Apply the same TwistAngle to another selected viewport.
✅ 📐 Standardize rotated plan views between layouts.
✅ 🖱️ Use simple two-click viewport selection.
✅ 🧰 Work directly in paper space for layout production tasks.
Result:
🎯 The result is a faster way to match viewport orientation in AutoCAD and Civil 3D drawings.
📐 Layout viewports can be aligned to the same rotated view direction without manual angle calculations.
✅ The command improves sheet consistency for plans, profiles, details, and north-oriented viewports.
