By Ellen Finkelstein A revision cloud is an often-used means to indicate that certain areas of a drawing contain revisions. The cloud draws attention to the revision. It’s similar to using Track Changes in Microsoft Word, or highlighting text. The revision cloud circles the revised objects.

By Ellen Finkelstein Blocks and basepoints go hand-in-hand. Knowing how to work with basepoints can make your life much easier. It’s so frustrating to insert a block and have it disappear into outer space because the basepoint is in the wrong location!
The Basepoint option of the INSERT command
When you insert a block, a Basepoint option appears […]
By Ellen Finkelstein Everyone works with layers. Most of the time, you set up your layers in a template and that’s that. But when you need to make changes, a few tips can help make the process easier. Here are some of mine:
Create a similar layer: When you create a new layer, often you want its properties […]
By Ellen Finkelstein AutoCAD 2010 introduced a great new feature, parametric constraints. You can constraint objects in two ways:
Geometrically: You can constrain objects to meet at a point, be horizontal, be vertical, be perpendicular, be concentric, and more Dimensionally: You can constrain the dimensions of objects. For example, a you can constraint a line to be 4 […]
By Ellen Finkelstein Layer states let you save configurations of layer properties and states. For example, you might want a layer to be red sometimes, and blue at other times. You may need certain layers to be locked, off, or frozen when you’re editing one part of the drawing, but unlocked, on, or thawed when you’re editing another […]
By Ellen Finkelstein In a previous post, “Create a rectangle with a flexible corner,” I showed how to create a rectangle whose upper-right corner is stretchable, creating a flexible rectangle that doesn’t lose its shape. In this post, I show how to do the same with a dynamic block.
Thanks to Joel, whose comment to the earlier post […]
By Ellen Finkelstein The faster you can display the section of your drawing where you need to work, the faster you can get started drawing and editing. With that in mind, here are some tips for viewing your drawing:
Use the mouse wheel
The mouse wheel is the key to fast view changes:
You can zoom in and […]
By Ellen Finkelstein A region is an interesting type of AutoCAD object. You can think of it as a 2D surface. Regions are always closed and they look like polylines, but AutoCAD can do some interesting things with regions, such as:
Calculate centroid, moments of inertia, and products of inertia Extrude them to create 3D solids Combine (UNION […]
By Ellen Finkelstein Sometimes you need to create a closed polyline from several existing objects that don’t meet end to end.For example, let’s say that you want to draw a polyline from the inside border created by the rectangle and two circles.
The BOUNDARY command is a very easy way to do this.
Start the BOUNDARY command to […]
By Ellen Finkelstein Some coordinates are easy to find. For example, to find the endpoint of a line, you just use the Endpoint object snap.
But others are more elusive.
For example, recently someone asked me, “I would like to ask if there is a simple way to select a center of a rectangle.”
My answer was: If […]
