Combine several functions into one dynamic block

1. With some study, you could create a custom block which scales, rotates, and stretches specific objects within the block having different effects, depending on which operation you perform first. 
2. The possibilities are endless and you only need some imagination to find powerful uses for these dynamic blocks.

Parameters and Parameter Sets - A Parameter Set is a combination command in the Block Authoring Palette which combines the parameter with its Action. 

1. Visibility- Allows several instances of the block to reside simultaneously together by turning on and off various objects. An example block can be found in the 24-36 SHEETSET TITLE Tab of S:/ACAD/CIVIL3D Template/C3D Template.dwt as the barscale in the lower right corner.  Click on the block, click on the Pentagonal grip, select the scale for the sheet.

         1. Highlight the Visibility Parameter
         2. Right click
         3. Select Visibility States

            3. Click on Set Current
            4. Click OK
      2. Set Visibility Status
         1. Highlight Object
         2. Right click/ Select Object Visibility
            1. Select one of the four visibility options for those objects
               1. Hide for current state
               2. Show for current state
               3. Hide for all states
               4. Show for all states
2. X-Y Stretch Box Set--This parameter set allows you to stretch an object in each of two mutually perpendicular directions at the same time.  An example is in S:/ACAD/Design Center/Design Center.dwg in the 340-720Chamber block.  By stretching the gravel border, the gravel hatch follows because it is associative to the border.
   1. Make sure you have in mind which objects you want to be able to stretch in each linear direction. 
   2. Select X-Y Stretch Parameter Set
   3. Click on the corner of the origin of the stretch action
   4. Click on the diagonal corner of the stretch action
   5. Click on one stretch action and right click
   6. Select Action Selection Set/New Selection Set
   7. Click on the first corner of the selection frame and then the opposite corner, just as you would in the standard stretch command
   8. Select the objects you wish to stretch...in the example, just the rectangular pline (the hatch is associative and does not stretch)
   9. Press Enter
   10. Repeat steps 2-9 for the other stretch parameter.
   11. If you wish to have the stretch operate incrementally,
       1. Highlight the distance parameter
       2. Right click and select Properties
       3. Type in the increment under Horizontal Distance and Vertical Distance.
3. X-Y Array Box Set-This parameter set allows you to repeat a rectangular array using any of four grips.  The arrayed objects simply repeat in both directions like a checkerboard.  An example is in S:/ACAD/Design Center/Design Center.dwg in the 340-720Chamber block.
   1. Select X-Y Array Box Set
   2. Click on  the origin corner
   3. Click on the end point diagonally from the origin
   4. Highlight one Array Action
   5. Right Click and select Action Selection /New Selection set
   6. Click on the objects you want to be in the array
   7. Press Enter
   8. Repeat steps 4-7 for the other Array Action
   9. To Set the Row and Column Offsets
      1. Highlihgt the Array Action in one direction
      2. Right Click and select Properties
      3. Type in the Row Offset and Column Offset
4. Rotate - The Rotate parameter set provides a quick way to rotate something in the block, and even the entire block using a grip.  An example can be found for the Text orientation for the dynamic north arrow so you can insert the block at north orientation and then rotate the text to plan view. S:/ACAD/C3D Template/C3D Template.dwt   (north-dyn block)
   1. Select Rotation parameter set
   2. Click on the center point of rotation
   3. Click on the outer radius
   4. Click for the maximum angle
   5. Click for the location of the grip
   6. While these items are highlighted, you may grip and adjust each one of them individually
   7. Highlight the name Rotate
   8. Right Click
   9. Select Action Selection Set/New Selection Set
   10. Select the objects you wish to rotate with this command
   11. Click Enter
5. Point Parameter allows you to insert a grip for moving the block (you must use the move parameter to move parts of the block)
   1. Select the Point Parameter
   2. Click at the exact place where you wish the grip to reside
   3. Click on another location to place the point label
   4. Right click on the label
   5. Select Rename Label
   6. Type in the new name for the label
6. Alignment Parameter - allows you to orient the block either parallel or perpendicular to line or p-line in the drawing.  This does not work with AEC objects like pipes and surfaces.
   1. Select Alignment Parameter
   2. Click to position the grip point
   3. Rotate and click to establish the orientation line
   4. Toggle orientation
      1. Highlight the Alignment Parameter

   3. Click (may use snaps or ortho) to specify the other end of the mirror plane.
   4. Drag the grip to a convenient location

   6. Add Selection Set
      1. Highlight the name Flip Set
