Update: Convert text to Mtext and back

autocad_tips_text-to-mtext-back-1This is an update of an earlier post Convert Text to Mtext and Vice Versa.

AutoCAD offers several types of text or annotation objects. Some are for dimensions or at the end of leaders, for example. But the most common type is text that you use as labels–and there are 2 types. The original type was called single-line text (or Dtext). When you use single-line text, every line is a separate object, ideal for short labels.

But many drawings require lengthy annotation in paragraph form and for that reason Mtext (multiline text) was introduced many years ago. You can format text almost any way you format text in your favorite word processor.autocad_tips_text-to-mtext-back-2

But sometimes, you have single-line text that should be Mtext, or vice versa. I have some old drawings that were created before Mtext! Here are 2 ways to convert between text and Mtext.

Convert single-line text to Mtext

Here’s some text in an old drawing that is single-line text. You can see that one of the lines is selected. It’s a plat description and of course, it should be Mtext. To convert it, use the Express Tools command TXT2MTXT. From the ribbon, choose Express> Text> Convert Text to Mtext.

autocad_tips_text-to-mtext-back-4At the Select objects: prompt, select the text objects that you want to convert. Usually, a window works best for selecting. After all, you don’t want to have to select each line of text individually!

If you press Enter instead, you get the Text to MText Options dialog box, shown here. By default, the command sorts from the top object downward and tries to word wrap the Mtext that it creates. You can choose to order the text by the order you selected it.autocad_tips_text-to-mtext-back-3

One cool feature of TXT2MTXT is that if you select the text objects first, the command executes without further input — very efficient! Also, the command does a true conversion by deleting your old single-line text objects.

You can see that you now have a single MText object.

autocad_tips_text-to-mtext-back-5

Convert Mtext to single-line text

Sometimes, you need to reconfigure your text because it won’t fit anywhere as a paragraph. In these situations, you can convert the Mtext to single-line text.

One way to convert Mtext to text is to copy and paste. Double-click the Mtext to open the Mtext editor. Select the text and copy to the clipboard. Then close the editor.

Start the TEXT command. Specify the start point, height and rotation angle as usual. You’ll then see a small box and cursor. Paste from the clipboard and press Enter to end the command. The text becomes all one line (which can get pretty long if you have a lot of text). Then delete your Mtext object.

Or you can simply explode the Mtext. This method keeps the line wrapping. It all depends on which result you want. A plus is that you don’t have to delete the original object.

Using the Geometric Center object snap

The Geometric Center object snap is new for AutoCAD 2016. It seems to me that there hasn’t been a new object snap for a long time. Am I right? When do you think that last new object snap was introduced and what was it?

Now that the trivia contest is set, let’s get into it. It’s really very simple. You need a closed polyline to use it.

  1. Start a command, such as the LINE command
  2. Access the list of objects snaps — by pressing Shift and right-clicking or using the list on the status bar. You can also use the keyboard shortcut, GCE.
  3. Choose Geometric Center and click to specify the start of the line.autocad-tips-geometric-center-2
  4. End the line wherever you want.

One cool point is that the geometric center doesn’t have to be inside the polyline. In this example on the right, the X marks the geometric center of the closed polyline.

The 1-minute video below shows an example of drawing a line from the geometric center of a closed polyline.

Are you going to use this new object snap? How will it be useful to you? Leave a comment!

AutoCAD 2016 – 30 releases young and still going strong – Part 3

lee ambrosiusThis is a guest post from Lee Ambrosius, who was my co-author for the AutoCAD 2015 and AutoCAD 2015 LT Bible. As you can tell from the photo, he’s a runner — even in some pretty cold Wisconsin weather! Lee is both an Autodesk Authorized Developer and Authorized Author. He’s also the author of the upcoming AutoCAD Platform Customization, His website is hyperpics.com

AutoCAD 2016 is the latest in a long line of AutoCAD releases that dates back over 30 years ago. The latest release offers a number of changes that improve 2D drafting operations, rendering 3D models, and much more.

There is a lot to cover, so Lee suggested that we split it up. In Part 1 we started with changes to the user interface and 2D drafting. Part 2 covered annotation and external file changes. Here in Part 3, we talk about new 3D and CAD management features.

Replace text in AutoCAD

Suppose that you want to rename some text labels. For example, you have some part numbers that start with G- and now you want them to start with J- or you want to change every instance of “box” to “rectangle”.

First, it may be hard to find all of the instances of the text you want to change and if there are a lot of changes, it would be very time consuming to change each one individually. Instead, you can use the FIND command, which lets you find and replace text anywhere in your drawing. It finds the following types of text:

  • Single-line text
  • Multiline text
  • Text in tables
  • Block attributes
  • Dimensions
  • Hyperlinks and hyperlink descriptions

autocad_tips-replace-text-1Choose Annotate tab, Text panel, Find Text, and enter the text you want to find in the Ribbon’s text box. Then click the Find Text button or just press Enter.

The Find and Replace dialog box opens with the text you entered in both the Find and Replace text boxes.

You can use wildcard characters: Continue reading Replace text in AutoCAD

Guest Tutorial: Make a 3D speaker in AutoCAD

This week’s very cool guest post is by Jaiprakash Pandey.jaiprakash pandey Jaiprakash is a Mechanical Engineer, Blogger, Corporate trainer and yes, self proclaimed charcoal artist too!  He is active on many CAD forums including Autodesk and AUGI forums, and is a certified AutoCAD 2014 professional who has been doing corporate training for three years. You can read more at his blog, SourceCAD.

In this project, solid and surfacing tools have been used to create the 3D model of speaker,   LOFT, TORUS , SPHERE, SLICE and PRESSPULL have been used primarily. This project is intended for advanced users. Although a beginner can also follow instructions and make the drawing easily, it is strongly suggested that the beginner explore basic projects before moving to these advanced projects.

Guest Post: Draw a circle with radius tangent to two objects

Today’s post is from Jason Bewerk. Jason is a blogger and CAD-enthusiast. He works full-time at a design firm and enjoys helping others with CAD and thus started 12CAD.com to provide detailed tutorials and exercises for everybody to use.

In the exercise below, you don’t draw the entire figure, but just focus on creating the circles that would be the basis for the figures perimeter.

We have the image below to replicate, and luckily we are given all dimensions, which will make the task simpler. Today’s difficulty is simply to learn how to draw a circle with specified radius tangent to two objects. As you can see from the figure below, we need to be able to create the R180 circle and R75 circle.

hatchautocad

The line AB in the figure below forms an angle of 30 degrees with the horizontal. To draw this line, follow these steps:

  1. Activate the LINE command
  2. Click on point A
  3. Write @210<30
  4. Hit the ENTER key

create a circle tangent in autocad

To obtain the two large circles, you will have to make sure the OBJECT SNAP mode is set in a way to let AutoCAD detect Tangent points, and use the CIRCLE command shown below.

tangent circle autocad

Find this command and use it to draw the two large circles. I hope this exercise was simple and you were able to complete it. If you had trouble, please check the previous exercises. Otherwise, I look forward to having you here for Day 9’s exercise.

Track the time you spend on a drawing

autoacad-tips-time-commandWhether you need to bill your clients the time your work on a drawing or just want to know how efficient you are (maybe your boss wants to know), you can do it in AutoCAD. You do this with the TIME command, which automatically tracks the time you work on a drawing.

To use the TIME command, enter time on the command line.

You see the following listing:

  • Current time: Obviously, this shows the current time, but also includes the date
  • Created: The date and time  the drawing was created
  • Last updated: The time when the drawing was last saved
  • Total editing time: The accumulated ime spent in the drawing from session to session. AutoCAD does not include plotting time or time that you worked but quit without saving your changes
  • Elapsed timer: Also accumulated time spent in the drawing, but you can turn this on and off as well as reset it
  • Next automatic save in: Shows when your drawing will be automatically saved. Use the OPTIONS command and display the Open and Save tab to set how often you want to automatically save your drawing

Next is the Enter option [Display/ON/OFF/Reset]: prompt. Here’s what those options do:

  • Display: Updates the listing with current times
  • ON and OFF: Turns the elapsed time on and off
  • Reset:  Resets the elapsed time to zero

Using these options, you can keep track of the time you spend on a drawing.

Another option

The Express Tools EDITTIME command (type it on the command line) tracks active editing time. It can represent your actual work more accurately than the TIME command, but you need to start it to start tracking. You can reset the time and use the timeout option to suspend counting after a certain period of inactivity.
