AutoCAD 2010 Training



Aims and Objectives

The aim of this tutorial is to let you practice solid modeling by revolving 2D polyline, making primitive solid box, and subtraction. After studying this tutorial, you should be able to:

     dot.gif (829 bytes)use the paper space of a drawing to construct a drawing document,
dot.gif (829 bytes)construct floating viewports, and
dot.gif (829 bytes)construct a 2D engineering document from a 3D object.


AutoCAD has two working environments, model space environment and paper space environment. To construct a model, you work in model space. To construct a 2D engineering drawing from the objects that you construct in model space environment, you switch to paper space environment. In paper space environment, you perform two tasks, inserting an engineering title block and constructing floating viewpoints to display orthographic views of the objects constructed in model space. Figure 1 shows a 3D solid model and Figure 2 shows the engineering drawing of this model.

Command: MENUBAR
Enter new value for MENUBAR <0>: 1

Then, unit of insertion scale is set to mm.

Select <Format> <Units…>. See figure 3 and 4

To display the Layout and Model Tab, right click PAPER /MODEL of the Windows status bar and select Display Layout and Model Tabs. See Figure 5.

To hide the Layout and Model Tab, right click Layout and Model Tabs and select hide Layout and Model Tabs. See Figure 6.

As we have said, documentation consists of two main tasks: Insertion of an engineering drawing title block and making of floating viewports. To change to paper space environment, select the [MODEL] button of the Windows status bar. See Figure 7.

After setting to paper space, the screen becomes white. And the UCS icon changes to a set square. See Figure 8.

Then, the format of layout should be set. See figure 9

Before you construct a document from your 3D object, you should have an engineering title block ready for insertion. See Figure 13. This title block has miscellaneous information. You can define attribute in this title block to save your time during insertion. Download the a4 template here

Insert Title Block

Use the DDINSERT command to insert a drawing title block. See Figure 18, the Insert dialog box. Select the file A4.dwg. Then uncheck the Specify Parameters on Screen box. After that, select the [OK] button. See Figure 18.

Because the linetype Center and Hidden are required, use the LINETYPE command to load these two linetypes to your drawing. See Figure 22.

<Properties panel> <Linetype...>

Now use the SOLVIEW command to construct an engineering drawing view. The SOLVIEW command enables you to construct four kinds of drawing views: UCS views, orthographic views, auxiliary views, and section views. Because the orthographic, auxiliary, and section views require a parent view, you have to use UCS views. Select the WCS as the UCS view and set the view display scale to 0.5. Then select a center position and two diagonal corners. After that, specify a drawing view name. See Figure 23.

<Modeling panel> <Solid View>

Command: SOLVIEW
Enter the option [Ucs/Ortho/Auxiliary/Section]:
Enter the option [Named/World/?/<Current>]:
Enter view scale<1>:
Specify view center:
[Select A (Figure 23).]
Specify view center:
Specify first corner of viewport :
[Select B (Figure 23).]
Specify opposite corener of viewport
: [Select C (Figure 23).]
Enter view name:
Enter the option [Ucs/Ortho/Auxiliary/Section/<eXit>]:

Use the LAYER command. You will find that 11 additional layers are constructed. They are:


For each viewport except the section view, there are three layers. Their names are the viewport name suffixed by -dim, -hid, and -vis. They will be used for dimensioning, placing the hidden lines, and placing the visible lines, respectively. For the section view, there is the fourth layer, -hat, which is used for the hatching lines. Finally, the Vports layer is reserved for the floating viewports.

See Figure 27.

The viewports now show the 3D object. To project a 2D drawing from the 3D objects, use the SOLDRAW command to construct drawing views. See Figure 28.

To complete the drawing, turn off layer Vports and set the current layer to 0. See Figure 29.

Key Points

Documentation of a 3D solid involves two major tasks to be done in paper space environment, insertion of an engineering drawing title block and making floating viewports.
