If you’re using AutoCAD for long period of time and you know how to use the AutoLISP and the importance of it. You probably know how to load the AutoLISP file in AutoCAD, and you certainly don’t need to read this tutorial. But if happens that you are relatively new on using the AutoCAD and you want to expand your knowledge in this drawing application software, then this tutorial is for you.

Sometimes while doing our job in AutoCAD there is some instances that happens unexpectedly. And one of that is the accidental turning off of the command line, and with that, you are unable to see the command that you’re keying-in.

Fig.1

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 came unexpectedly. 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.

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.

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?.

Traditionally, dimensioning in model space is the preferred method for dimensioning a drawing, whether it’s a single view, multi-view, complex or just a simple drawing.

I don’t know if this cool AutoCAD routine called Break-Line, in Express tools was already around in the previous version of AutoCAD. Because I haven’t saw this in the previous version of AutoCAD that I’m using, the AutoCAD 2004. It is only just this year that I’d use AutoCAD Architecture 2008, so I have no idea if, whether ther was a already Break-Line Symbol exists, or maybe I just to busy to notice its existence? hhmmm.
