Navigate Multiple Layouts — Alan Houston — This LISP routine helps navigate drawings with large number of layouts. When the number of layout tabs is greater than the number that can be shown in the layout tab area, navigating them manually can become tedious and, in some cases, almost impossible due to certain issues in AutoCAD.
Persistent Grips — Brian Bennett — When working with long polylines and splines, you may find it desirable to have persistent grips to help with visibility and printing. This LISP routine will create “point” entities at the endpoints and vertices of lines, polylines, and splines.
Exaggerated Offset — Leland Leahy — The author uses this LISP routine in the civil engineering industry when working with profile views with exaggerated scales. For example, with a scale of 1”=20’ horizontal and 1”=5’ vertical, set the exaggeration to 4, and this command will scale your offsets to generate the correct geometry.
Quick Edit/Properties for Civil 3D Objects — Leland Leahy — This routine will open up the correct properties or editing command depending on the object selected in AutoCAD Civil 3D. For example, if you select a pipe network structure, the Structure Properties dialog box will open. If you select an alignment, the Alignment Properties dialog box will open.
