Process Overview: Creating Multi-View Block Definitions
There are four general steps for creating a multi-view block:
Step 1: Create a set of view blocks for each view direction in every display representation you need.
For example, if you need a multi-view block definition that displays in Model view and Reflected Plan view,
create a set of views for each representation. You create views only for those view directions where you want
a different result. For example, if the top and bottom views are supposed to look the same in the Reflected
Plan display representation, you draw the view block only once, and assign it to both view directions.
Step 2: Create a multi-view block definition in which you assign the view blocks to view directions in individual
display representations.
Step 3: If you want the new multi-view block definition to be available through DesignCenter
™
, add the definition
to DesignCenter.
Step 4: If you want the new multi-view block definition to be available from a tool palette, add it to a palette.
Creating View Blocks
Use this procedure to create AutoCAD blocks to represent each view of the multi-view block definition in display
representations.
1 Draw the views you need for a specific display representation:
Then… If you want to…
draw them on the XZ plane. create views for the front and back directions
draw them on the YZ plane. create views for the left and right directions
draw them on the XY plane. create views for the top and bottom directions
create a block containing objects, such as mass elements, to
be used as the subtractive body. create a block for an interference condition
2 Specify additional insertion points on the Defpoints layer through the AutoCAD point command, if
necessary.
NOTE The points added to view blocks are cumulative. For example, if you add one point to a view block used
for the top view and two points to the view block used for the model view, you have a total of four points to
cycle through. The fourth point is the regular base point defined during the creation of the block.
3 Select the World Coordinate System before making blocks from these individual views.
For more information about coordinate systems, see “Use Coordinates and Coordinate Systems” in AutoCAD
Help.
4 Define each view as a block, and coordinate the location of the insertion base point as you define each
block.
For example, if you specify the insertion base point of the model view block as the midpoint of the bottom
edge on the back side, the front and back view blocks have an insertion base point at the midpoint of the
bottom edge. Then, the left and right view blocks have an insertion base point at the bottom corner on
the back side, with the insertion base point for the top and bottom view blocks at the midpoint of the back
edge.
For more information about blocks, see “Create and Use Blocks (Symbols)” in AutoCAD Help.
