REFEDIT or Reference Edit, is a command that modify blocks and external references  or Xref, and redefine block definitions within the current drawing. So if there something you want to modify, some portions of the blocks or external reference from your drawing. Then REFEDIT is the command you can always trust in doing so.

I know all of us AutoCAD users, has experienced losing our drawing files when a program system failure unexpectedly came. Or sometimes when a power failure or a software problem happens right in the middle of doing our work. And because it is too sudden, most of the times we haven’t saved our drawings.

Object Snap or Osnap for short, is an AutoCAD command primarily use to specify precise locations on objects, from your drawing. Therefore this command works to make your drawing more accurate and reliable. For example, you can use an object snap to draw a line to the center of a circle, or to the midpoint or endpoint of any polyline segment.

I think it is safe to say that, most of the advance AutoCAD users, knows how to use AutoLisp, they might even know how to do a routine by themselves as well.  Just like some of my colleagues, back in the previous company that I’ve been work with. Some of my colleagues there are AutoLisp fanatics, they even develop an AutoLisp routine of their own. And I can even say that I know how to do a AutoLisp routine, albeit not that complex as some of my colleagues does.

Regions are two-dimensional enclosed areas that have physical properties such as centroids or centers of mass. Two or more existing regions can be combine into a single, complex region to calculate an area.

A multi-faceted object on your drawing, will consumed most of your time dimensioning it, if you don’t know the techniques, or the commands that can be use to dimension it continuosly and automatically.

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.

How to add a breakline symbol to a dimension line?, that’s the question. Sometimes in a AutoCAD Draftsman’s career, they will encounter such drawing that has an object that needs to be shown with breakline symbol in order to fit the drawing inside the drawing area. And ofcourse a drawing cannot be called as a working drawing if the drawing has no Annotations, Title, and specially if no Dimensisons.

While doing some visitor tracking in this CAD blog, I came across with a search query “how to change dimension text” in this site’s referral url. Which makes me wonder, what does the searcher really need to know, when he/she makes that search. Is the searcher wants to change the Text content of the dimension or was he/she wants to change te properties of the text in the dimension?.
