Residential Driveway & Garage Turning Planner Pro

Explore vehicle turning space directly inside AutoCAD with Residential Driveway & Garage Turning Planner Pro.

This AutoLISP and DCL program helps residential designers and CAD drafters visualize simple forward and reverse maneuvers when planning driveways, garage approaches, and turnaround areas.

Features:

• Enter vehicle wheelbase, body width, and front/rear overhangs
• Set a rear-axle path radius and turn sweep
• Choose left or right turns and forward or reverse travel
• Add a clearance buffer around the vehicle
• Draw sampled vehicle positions and buffered outlines
• Generate a rear-axle path and full-circle radial guide bounds
• Adjust outline spacing for closer visual review
• Place and rotate the maneuver using two picked points
• Scale drawing output for inches, feet, millimeters, or meters
• Export local maneuver positions and headings to CSV
• Organize output on dedicated CAD layers

Your download includes:

• Residential Driveway & Garage Turning Planner Pro LISP file
• Matching DCL interface
• Installation and usage instructions
• Example maneuver CSV
• Validation notes

Command:

TURNPRO — Opens the turning planner interface.

Compatibility:

Designed using AutoCAD 2002-era AutoLISP, Visual LISP, ActiveX, and DCL functions for Windows AutoCAD. Live AutoCAD compatibility and interface testing remain pending.

Important notice:

This is a preliminary 2D planning tool for a rigid rectangular vehicle following a constant-radius maneuver. Clearance review is visual; automatic obstacle collision detection is not included. Sampled outlines and full-circle guide bounds do not represent an exact finite-turn swept-area polygon. The program does not simulate trailers, slopes, steering transitions, or multi-point turns, and does not certify garage access or code compliance. Verify vehicle dimensions and use an appropriate validated swept-path workflow for final approval.
