• ## Free AutoCAD course - online

This is the content of the free online AutoCAD course. It is made up of 8 consecutive sections, within which there are more than 400 videos and explanations of how AutoCAD works. FIRST SECTION: BASIC CONCEPTS Chapter 1: What is Autocad? Chapter…

• ## 12.1 Geometric Restrictions

As we just mentioned, geometric constraints establish the geometric arrangement and relationship of objects with respect to others. Let's see each one: 12.1.1 Coincidence This restriction forces the second selected object to coincide in some of its points...

• ## CHAPTER 12: PARAMETRIC RESTRICTIONS

When we use an object snap endpoint, or center, for example, what we are actually doing is forcing the new object to share a point of its geometry with another object already drawn. If we use a reference...

• ## CHAPTER 11: POLAR TRACKING

Let's go back to the “Drawing Parameters” dialog box. The “Polar Tracking” tab allows you to configure the feature of the same name. Polar Tracking, like Object Snap Tracking, generates dotted lines, but only when the cursor crosses…

• ## CHAPTER 10: TRACKING OF REFERENCE TO OBJECTS

“Object Snap Tracking” is a valuable extension of the “Object Snap” features for drawing. Its function is to lay out temporary vector lines that can be derived from existing “Object Snaps” to signal…

• ## 9.1 .X and .Y Dot Filters

References to objects such as “From”, “Midpoint between 2 points” and “Extension” allow us to understand how Autocad can indicate points that do not exactly coincide with the geometry of existing objects but can be derived from it, an idea that…

• ## CHAPTER 9: REFERENCE TO OBJECTS

Although we have already reviewed several techniques to accurately draw different objects, in practice, as our drawing becomes more complex, new objects are usually created and always located in relation to what has already been drawn. I mean, the…

• ## 8.5 Tables

With what we have seen so far, we know that "pulling" lines and creating text objects from one line is a task that can be done quickly and easily in Autocad. In fact, it would be all that would be needed to create tables…

• ## 8.4 Multiple Line Text

On many occasions, drawings require no more than one or two descriptive words. In some cases, however, the necessary notes may be two or more paragraphs. So using one line text is absolutely...

• ## 8.3 Text Styles

A text style is simply the definition of various typographical features under a certain name. In Autocad we can create all the styles we want in a drawing and then we can associate each text object to a style...

• ## 8.2 Editing Text Objects

From chapter 16 onwards we cover topics that have to do with editing drawing objects. However, we must see here the tools available for editing the text objects we just created…

• ## 8.1.1 Fields in text

Text objects can include values ​​that depend on the drawing. This feature is called "Text fields" and they have the advantage that the data they present depends on the characteristics of the objects or parameters...

• ## 8.1 Text in a line

In many cases, drawing annotations consist of one or two words. It is common to see in architectural plans, for example, words like "Kitchen" or "North Facade". In situations like this, text on one line is easy...

• ## CHAPTER 8: TEXT

Invariably, all architectural, engineering or mechanical drawings require text to be added. If it is an urban plan, for example, it may be necessary to add the names of the streets. Drawings of mechanical parts are usually…

• ## 7.4 Transparency

As in the previous cases, we use the same procedure to set the transparency of an object: we select it and then set the corresponding value in the “Properties” group. However, it should be noted here that the value of transparency does not…

• ## 7.3 Line thickness

Lineweight is just that, the width of an object's line. And as in the previous cases, we can modify the line thickness of an object with the drop-down list of the “Properties” group of…

• ## 7.2.1 The alphabet of lines

Now, it is not about applying different linetypes to objects without any criteria. In fact, as you can see from the linetype names and descriptions in the “Type Manager…

• ## 7.2 Types of Lines

The linetype of an object can also be changed by choosing it from the corresponding drop-down list in the Properties group on the Home tab, when the object is selected. However, the initial settings of Autocad for new drawings only…
