completely enclosed will be selected.
Fence:
With the Fence option of the Lasso selection you can place the mouse cursor in any position you choose. For this example place your cursor at (P1) then press and hold the left mouse button. (Do not release the mouse button.) Move the mouse until you see either the green or blue lasso, then press the Spacebar until you see just a Dashed Fence Line. Move the mouse over the objects you want to select (P2) then release the left mouse button. Only the objects that the Fence line crosses will be selected.
Note: You may have to press the Spacebar twice to activate the Fence Line option.
There are 3 methods to erase (delete) objects from the drawing. They all work equally well. You decide which one you prefer to use.
Method 1.
Select the Erase command first and then select the objects.
Example:
1. Start the Erase command using one of the following:
Ribbon = Home Tab / Modify Panel /
or
Keyboard = E <enter>
2. Select objects: Pick one or more objects
Select objects: Press <enter> and the objects selected will disappear.
Method 2.
Select the Objects first and then the Delete Key.
Example:
1. Select the object to be erased.
2. Press the Delete Key.
Method 3.
Select the Objects first and then select Erase command from the Shortcut Menu.
Example:
1. Select the object to be erased.
2. Press the right Mouse button.
3. Select Erase from the Shortcut Menu using the left mouse button.
Note: Very Important
If you want the erased objects to return, select the Undo tool
More about Undo and Redo on the next page.
The Undo and Redo tools allow you to undo or redo previous commands.
For example, if you erase an object by mistake, you can UNDO the previous “erase” command and the object will reappear. So don’t panic if you do something wrong. Just use the UNDO command to remove the previous commands.
The Undo and Redo tools are located in the Quick Access Toolbar.
Note:
You may UNDO commands used during a work session until you close the drawing.
How to use the Undo tool.
1. Draw a line, circle and a rectangle.
Your drawing should look approximately like this.
2. Next Erase the Circle and the Rectangle.
(The Circle and the Rectangle disappear.)
3. Select the Undo arrow.
You have now deleted the ERASE command operation. As a result the erased objects reappear.
How to use the Redo command:
Select the Redo arrow and the Circle and Rectangle will disappear again.
Starting a new drawing means that you want to start with a previously created Template file. That is why I taught you “How to create a template” at the beginning of this lesson. You will use either the inch-helper.dwt or the metric-helper.dwt template each time you are instructed to start a new drawing.
Note: Do not use the New tool if you want to open an existing drawing.
Refer to page 2-19 to open an existing drawing file.
How to start a new drawing
1. Select the New tool from the Quick Access Toolbar.
2. Select either the inch-helper.dwt or the metric-helper.dwt from the list of templates.
Note If you do not have these templates, refer to page 2-2 for instructions.
3. Select the Open button.
Opening an Existing Drawing File
Opening an Existing Drawing File means that you would like to open, on to the screen, a drawing that has been previously created and saved. Usually you are opening it to continue working on it or you need to make some changes.
1. Select the Open tool on the Quick Access Toolbar.
2. Locate the Directory
