Tipster James D. King shares a tip for using AutoCAD’s Change command to straighten linework.
"This tip can help you straighten a line or lines that are slightly askew. I use the Change command with Ortho on and osnap set to endpoint. I also use CH for my hot key. For this I set CH to '-change' in alias editor. First, type ch, then select the line and the endpoint of the line; the line will snap straight. It does this because Ortho will only allow this line to be searched in Ortho. You can also do multiple lines at one time. If you turn off Ortho and do multiple lines, it will pull them all together. This is cool, too, but I haven't found a use for it other than as a training exercise."
Notes from Cadalyst Tip Reviewer Brian Benton: The Change command in AutoCAD can alter many properties of an object. By default it changes the location of a point on a line (or object). This tip uses object snaps and the Ortho setting to have the command force a line’s endpoint to a horizontal or vertical position (relative to its first endpoint). You can also use the Change command to alter color, elevation, layer, line type, LT scale, line weight, thickness, transparency, material, or annotative setting.
