Track Geometric Points in AutoCAD

Find points in relation to existing geometry without extra geometry.

By John Hackney

While designing in AutoCAD, you often want to sketch to coordinates that are referenced from existing geometry. AutoCAD offers a few tools that can help with this task and avoid the addition and management of construction lines. Most AutoCAD users are familiar with the object snap (osnap) Extension function — which can be combined with object snap tracking to find needed coordinates from existing geometry — but there are a few more commands and sub-commands that not all users are as familiar with. These commands include From, Point Filters, Temporary Tracking Points, and Tracking. This Tech Tip will explain the use of the last two.

To illustrate these commands, we will use a simple design of a bearing and the machine side plate to mount two of these bearings on.

The final drawing.

We want to make sure our AutoCAD osnap settings are correct. For this exercise, make sure Endpoint, Center, Midpoint, Intersection, and Extension are selected as running osnaps. Also be sure the Object Snap Tracking option is enabled on the status bar. For this exercise we will turn off Dynamic Input, either by selecting the icon on the status bar or by pressing the F12 key.

ARES Commander Edition

Low-cost 2D/3D CAD software holds promise as an AutoCAD replacement for some, including Mac, Linux, and mobile device users down the road.

By R.K. McSwain

When I first heard about a new, low-cost 2D and 3D CAD application that is DWG-compatible and supports LISP, I was pretty excited. ARES Commander Edition from Graebert is all that and more. Could this be a replacement or supplement for AutoCAD in your office — or mine? Let's find out.

Berlin, Germany–based Graebert (formerly known as GiveMePower) announced ARES at Macworld in February. Macworld, you ask? That's right. The buzz about this brand-new software is partly due to the fact that soon it will be offered for the Mac as well as Linux, and eventually for Microsoft Windows Mobile devices too.

The software is available in two versions: ARES ($495) and ARES Commander Edition ($995), both of which support 13 languages. For this review, I looked at ARES Commander Edition, which offers the complete 2D CAD functionality of ARES (similar in form and function to AutoCAD LT), plus support for ACIS-based 3D solid modeling and for LISP and other custom programming add-ons.
