For February, Harry's picks include the following:

Ellipse Sampler — Ramakrishna Acharya — Although AutoCAD has offered full 3D modeling capabilities for some time, users still draw and sketch things in 2D as well. This routine will project circles in one view as an ellipse in another view. 

Resize Text and Mtext — Theodorus Winata — This small routine will help you scale multiple text and/or mtext entities individually about their insertion point in AutoCAD.

Draw Formed Shapes — Jay Thomas — Create a variety of formed shapes including angles, channels, and U or J shapes.

Join Multiple Entities by Layer — Alan Thompson — This AutoCAD routine will join supported entities on the same layer into polylines. 

Quickly Freeze and Turn Off Layers — Kent Cooper — The tip author has added more functionality to an existing tip, allowing you to pick layer 0 to freeze it, in which case another layer will be set to current.  

Quick Xref Control — Matt Sibum — This nice set of xref display–related commands includes five shortcuts for unloading, reloading, and isolating xrefs in AutoCAD.
