using Dimension Space

July 22, 2009 in AutoCAD, CAD

Dimension presentation is vital in a drawing, a drawing plans cannot be use if the dimension is not readable. Thats why it is important for us AutoCAD Drafters and Architects that we assure that, the dimensions are shown in a nice and in a readable way. But sometimes, in an unavoidable situation like rushing up yourself to finish your drawing and eventually making it to submission day. This is the time when your drawing presentation might suffer, specially the dimension presentation.

Goodthing, AutoCAD has this routine, that can automatically adjust existing parallel linear and angualr dimension in a drawing, so they are equally spaced or aligned at the dimension line with each other.

This routine called, the Dimension Space, or DIMSPACE, you can find this routine at the Dimension Pulldown menu, Dimension Space, you can also find it at the dimension toolbar (fig.1). Alternatively, at the command prompt, type DIMSPACE, then ENTER, then select the dimensions you want to adjust. The dimension that to be selected must be linear or angular, of the same type (rotated or aligned), parallel or concentric to one another, and on the extension line of each other. See the example below (fig.2 and fig.3).

Chamfering by Specifying Length and Angle in AutoCAD

July 9, 2009 in AutoCAD, CAD

You can chamfer two objects by specifying where on the first selected object the chamfer line starts. Then specify the angle the chamfer line forms with this object. In the following example, you chamfer two lines so that the chamfer line starts 1.5 units along the first line and forms an angle of 30-degrees with [...]

Chamfering by Specifying Distances in AutoCAD

July 9, 2009 in AutoCAD, CAD

The chamfer distance is the amount each object is trimmed or extended to meet the chamfer line or to intersect the other object. If both chamfer distances are 0, chamfering trims or extends the two objects until they meet but does not draw a chamfer line.

The default setting for the first distance is the last [...]
