Using the Presspull command

The last command in our 2D-to-3D conversion group is called Presspull. It is used to directly create an extrusion (or cut into the material) out of the face of a solid body. In addition to that, it can also directly extrude an enclosed 2D shape as we will see in this section. To start the Presspull command, you can type the command name PRESSPULL (or just type PRES) then press Enter, or alternatively you can click on the Presspull button found in the Create panel in the 3D Basics workspace, and if you are using the 3D modeling workspace, you will find the Presspull button in the Modeling panel under the Home tab, or in the Solid panel under the Solid tab, as shown in the following figure:

Figure 12.33: Alternative methods to start the Presspull command

You can use the Presspull command to quickly extrude faces of existing 3D solid objects as follows:

  1. After starting the Presspull command, move to the object face that will be extruded. Notice that the face edges will be highlighted in blue. Click to confirm the selection.
  2. Move to specify the extrusion height, or alternatively, you can enter the required height using the keyboard.
  3. When you arrive at the desired height, click or press Enter to finish.

The following figure shows an illustration of the previous steps:

Figure 12.34: Steps for using the Presspull command

Notice that after Step 3, the command will not terminate, letting you select another face to extrude, or to end the command press Esc or right-click.

The previous example showed how to extrude a face of an existing solid body, but the Presspull command can also be used to directly extrude an enclosed region, as shown in the following step-by-step example:

  1. Move the mouse cursor to the middle of an enclosed region. The borders of the region will be highlighted as shown in the first panel of the following figure. Click to confirm the selection.
  2. Move the cursor vertically to specify the extrusion height, or alternatively, you can type the height value then press Enter.
  3. After the height specification, you will be prompted to select another face (or enclosed region) to extrude. Press Enter to end the command.

The following figure is an illustration of the previous steps:

Figure 12.35: Using the Presspull command to create an enclosure 

As shown in the previous example, the enclosed open region between the two rectangles was automatically detected by the Presspull command. The same can't be done using the Extrude command, where you will create two solids then subtract the inner one to create the same shape in the previous example.

The Presspull command has one option that appears in the command bar after you select the face to be extruded. The option is called Multiple, and to activate this option you can type M and press Enter or you can click on the option name in the command bar. The Multiple option allows you to select multiple objects to be extruded at once as shown in the following step-by-step example:

  1. After starting the Presspull command and selecting one face, type M and press Enter to activate the Multiple option.
  2. Select the other faces to be extruded.
  3. Move the mouse to specify the height of all the extrusions simultaneously. Alternatively, you can enter the value using the keyboard.

The following figure shows an illustration of the previous steps:

Now that we learned about the 2D-to-3D conversion commands, let's have a look at the Flatshot command, which is used to create a 2D drawing from a 3D model.
