DIVIDE

      The DIVIDE command divides an object mathematically by the NUMBER of segments you specify. A POINT (object) is placed at each interval on the object.

      Note: the object selected is NOT broken into segments. The POINTS are simply drawn ON the object.

       EXAMPLE:

Image

      1. First open the Point Style box and select the POINT STYLE to be placed on the object.

Ribbon = Home tab / Utilities Panel / / Point StyleorKeyboard = ddptype <enter>
Image

      2. Next select the DIVIDE command using one of the following:

Ribbon = Home tab / Draw Panel / / orKeyboard = DIV <enter> Image

      3. Select Object to divide: select the object to divide

      4. Enter the number of segments or [Block]: type the number of segments <enter>

      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 / orKeyboard = E <enter> Image

      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 the 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 Image from the Quick Access Toolbar. This will Undo the last command. More about Undo and Redo later.

      The EXPLODE command changes (explodes) an object into its primitive objects. For example: A rectangle is originally one object. If you explode it, it changes into 4 lines. Visually you will not be able to see the change unless you select one of the lines.

      1. Select the Explode command by using one of the following:

Ribbon = Home tab / Modify panel / orKeyboard = X <enter> Image

      2. The following will appear on the command line:

      Command: _explode

      Select objects: select the object(s) you want to explode.

      Select objects: select <enter>.

Image

      (Notice there is no visible difference. But now you have 4 lines instead of 1 Rectangle).

       Try this:

      Draw a rectangle and then click on it. The entire object highlights. Now explode the rectangle, then click on it again. Only the line you clicked on should be highlighted. Each line that forms the rectangular shape is now an individual object.

      The EXTEND command is used to extend an object to a boundary. The object to be extended must actually or theoretically intersect the boundary.

      1. Select the EXTEND command using one of the following:

Ribbon = Home tab / Modify panel / orKeyboard = EX <enter> Image

      2. The following will appear on the command line:

      Command: _extend

      Current settings: Projection = UCS Edge = Extend

      Select boundary edges ...

      Select objects or <select all>: select boundary (P1) by clicking on the object.

      Select objects: stop selecting boundaries by selecting <enter>.

      Select object to extend or shift-select to Trim or [Fence/Crossing/Project/Edge/Undo]: select the object that you want to extend (P2 and P3). (Select the end of the object that you want to extend.)

      Select object to extend or [Fence/Crossing/Project/Edge/Undo]: stop selecting objects by pressing <enter>.

Image

      Note: When selecting the object to be extended (P2 and P3 above) click on the end pointing towards the boundary.

      Fence Use a “Fence” line to select objects to extend

      Crossing You may select objects using a Crossing Window

      Project Same as Edge except used only in “3D”.

      Edge (Extend or No Extend)
