For May, Harry's picks include the following:

Set Current Dimension Style — Theodorus Winata — This routine  allows you to set the current dimension style by selecting a dimension object.

Hook Hatch Pattern — Ted Kruysman — Ted calls this pattern "Hook" because it is an array of J-shaped figures that resemble the hooked side of a hook-and-loop fastener, such as Velcro.

Rotate Text — Neil Culver — This tip comprises four text rotation routines, the first three of which rotate text to absolute rotation angles of 0°, 45°, and 90°. The last routine rotates text 180° relative to its current angle, essentially flipping it.

Metric and Imperial Tools — Dave White — These three routines enable you to use imperial measurements in metric drawings, and vice versa.

Lock and Unlock Viewports — Theodorus Winata — Theodorus's tip allows you to lock or unlock all viewports with one quick command. This routine includes a good example of using a separate function where certain chunks of code must be called repetitively from different locations in the main function.

Dynamic Text Curve Align — Lee McDonnell — Lee shares a LISP routine that allows you to dynamically place text or mtext along a curve object, which in this context refers to a spline, arc, circle, or LWpolyline. If you change the curve, the text adjusts automatically.

Create Scale-Based Dimstyles — Scott Botting — Enter a scale factor or viewport and choose a font to create a dimstyle.
