How to Disable the Creation of BAK file

By default AutoCAD, creates a back up copy of the drawing every time you save or save as either with the current drawing name or with another name. Every update you’ve done, AutoCAD updates the back up files at the same time.

The Case of the Invisible Point Symbol

Why is it in my drawing the Point symbol is not visible? but when I open the other drawing the Point Symbol is visible?. That is the question thrown at me by my colleagues while doing her assigned task. 

To answer her question, the Point Symbol became invisible because of the POINTSTYLE. Perhaps  the default point style in her drawing was the first two point style type. [Fig.1]

Anyway to set your point style and size, just click Format menu then Point Style. [Fig.2]

How to Place a Text in an Arc

arcalignedtextHow to write a text around a circle? that was the question  that I have received in one of the yahoo groups that I recently joined. I have been doing AutoCAD works for 14 years and counting, but I have not known yet if there is a command regarding, writing a text in a circle.

However there is a command that I know that will allow you to place a text in an arc. And this command is Arc Aligned Text or ARCTEXT, this command can be found under the Express menu of AutoCAD, under the Text, then Arc-Aligned Text (fig.1). Or simply key-in on your command line  ARCTEXT (fig.2).

[fig.1)

[fig.1)

Firstly, you have to draw an arc and then use ARCTEXT command to place your desired text along the arc. You can sets control for text location relative to the arc and its length by using the pick boxes on the dialog box, the Drag Wizard on the pick box controls the behavior of the text  when the arc has been moved.  You can also specify the text height, width factor, offset from left or right, as well as character spacing on the properties section of the dialogue box. And lastly you can as well specify your desired fonts on the Text section.

Perhaps, there is already a command or a LISP for placing a text in a circle, I just don’t discover it yet. And that will be my assignment.

How to Draw a Straight Angular Line

Normally in AutoCAD you can only draw two types of straight lines, one is vertical line, the other is horizontal line, provided you’re working on ortho on mode. However you can always draw a straight angular line by turning your cursor to ortho off mode. But inspite of this, you cannot specify the exact angle of the line you’re going to draw.

So the easiest way in drawing a straight angular line with specific angle is by using another AutoCAD command, and one command I know that can be useful to perform this certain task is the SNAPANG command. SNAPANG is an AutoCAD command that sets the snap and grid rotation angle for the current viewport relative to the current UCS at your own specifc angle.

At the command prompt, just type, SNAPANG, then enter. Then enter the new value (e.g. 45). the current UCS will turn to 45 degrees. You can always get you cursor to the original rotation by entering 0 angle to your new value of SNAPANG.

snapang @ 0 degrees

snapang @ 0 degrees

 

snapang @ 45 degrees

snapang @ 45 degrees

Thats all for now.

Using TEXTFILL

 Have you sometimes encountered a scenario, when you plot your drawing then the TEXT in your drawing appeared only as an outline? (Fig.1) but if you look at it in AutoCAD it is appear as normal filled text. This happen specially if you are using the ARIAL type kind of fonts.
Fig.1

Fig.1

 

 Sometimes this thing happens because the value of the TEXTFILL was set in zero (0)by default the value of TEXTFILL is one (1).

So what is TEXTFILL?

TEXTFILL, is an AutoCAD command serve as to control the fillings of  TrueType fonts while plotting and rendering. You might wanna ask why the TEXTFILL value was set to zero (0) when the default should be one (1). The only scenario I can think of is, maybe the drawing that you are doing was just saved in a existing AutoCAD drawing file, and maybe the author of that existing AutoCAD file changed the default value of the TEXTFILL from (1) to (0).

Anyhow, if happens that you’re in this situation, just type-in TEXTFILL at the command prompt, then changed its value from zero (0) to one (1).

The next time you plot your drawing the TEXT will appear as it is in the image above.

How to Unhide Layout and Model Tabs

Just a moment ago, while doing my work on my AutoCAD, I accidentally hide the Layout and Model Tabs ( Fig.1)in AutoCAD.  At first, I was confuse what was just happen with my AutoCAD for I haven’t figured out that the Model Tabs was missing.

Text Under the Dimension Line

How do you put a text under a dimension line? No, I’m not talking about literally putting a Text under a dimension line using the command Text or Mtext then putting it under the dimension line manually. What I’m talking about is how are you going to a put Text under a dimension line automatically, without doing any command other than DIMEDIT or Edit.

Here is how, after a dimension was made in the object in your drawing, key-in command DDEDIT or just ED. Then click the text on the dimension line and add a backward  slash and a capital X after the dimension text (\X your text here). The result will be like those on the picture below (Fig.1).

Underlining a Text in AutoCAD

underlineSometimes putting a mark or putting a note in our drawing is necessary, specially if you want to specify something, then highlighting it, in order to notice it easily. In my case, whenever this  kind of scenarios arises, I always put an Underline and OverLine on my Text or Mtext, as a highlighter, making it easier to caught the readers of my drawing’s attention.

In AutoCAD, putting an underline or overline in a Text or Mtext is easy, that is, if you know the symbol or the special code to be use. So if happens that you don’t know what to be use, or you knew but forgotten it already due from not using it often. This blog post is for you.

So here is the code on how to put an Underline and Overline in a Text or Mtext. As well some other useful special codes to create an special symbols in AutoCAD.

How to Load an AutoLISP File

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.

AutoLISP a Brief Description

AutoLISP is based on the LISP programming language, which is simple to learn and very usefull in everyway. AutoLISP Applications or routines can interact in AutoCAD in many ways. These routines can prompt the user for input, access built-in AutoCAD commands directly, and modify or create objects in the drawing database. By creating AutoLISP routines you can add discipline-specific commands to AutoCAD. Actually, some of the standard AutoCAD commands are AutoLISP applications. Knowing how to load and use these routines can enhance your productivity.

Loading the AutoLISP

There are two methods to load an AutoLISP file, one is loading it by using the Customize User Interface editor or CUI, the other is by using the command Load Application or simply APPLOAD. Customize User Interface editor can be found by clicking the CAD Manager pulldown menu, then Customize, then Interface (fig.1).

Fig.1

Fig.1

Alternatively at the command prompt, key-in CUI. Then in the Customize Interface editor tab, in the Customizations in all CUI files pane, right-click LISP files, then click Load LISP. Then in the Load LISP dialog box, locate and select the AutoLISP file you want to load. Remember only files with the extension LSP can be selected here. After you selected the AutoLISP file that you want, click OPEN.

Load Application or simply APPLOAD, using this command is the easiest method in loading an AutoLISP file. You can find this command under CAD Manager pulldown menu on the same place where the Customize User Interface can be found. Or at the command prompt key-in APPLOAD. The good thing in using this method is, not only the AutoLISP files can be loaded but also some other AutoCAD Application files as well. Such as ObjectARX files (arx), VBA files (dvb), ObjectDBX files (dvx), Visual Lisp Executables (vlx), and Fast-load AutoLISP Format (das) [Fig.3].

How to Hide/Unhide Command Line

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

Fig.1

 

There is two way actually to hide the command window of AutoCAD or in these case to unhide.  One of these is on the keyboard shortcut, by pressing CTRL+9. The other is at the Tools pulldown menu, then Command Line (fig.1). Alternatively if you are using AutoCAD Architecture 2008 and beyond, you can find the command line in Window pulldown menu as well (fig.2).
