Description
Used to create a radius or chamfered blend between to faces that meet at a common edge. The edge is selected via the cursor, several edges may be selected then processed. The radius may be constant or linearly variable between two specified end values.
Alternatively used to assign a blend as an attribute to one or more edges or vertices. The network of blends so created is then processed in one operation using the FIX option. The command is also used to modify the setback information for vertex blends after the automatic algorithm has assigned values and to list the attributes of an edge or vertex.
Command Qualifiers
|
EDGE |
Specifies that the accompanying blend data is to be applied to an edge. |
|
/CHAMFER $N |
Specifies that a chamfer of width $N is to be created. Note: |
|
/ATTACH |
Specifies that the accompanying edge or vertex data is to be attached as an attribute to a selected edge or vertex for later processing. |
|
/VARIABLE $N $N |
Specifies that a variable radius blend is to be created. $N $N specifies the start and end radii respectively. |
|
$N |
With EDGE, specifies the radius value for a constant radius edge blend. |
|
/SETBACK $N <$N> |
Specifies the length of the setback on a selected edge at a chosen vertex blend. Optionally the setback length for the opposite end of the edge may also be given. |
|
/DIFFERENCE $N <$N> |
Specifies the difference between the upper and lower setback lengths for an angled setback at a selected end of an edge. Optionally the setback difference for the opposite end of the curve may also be given. |
|
VERTEX |
Specifies that the accompanying blend data is to be applied to a vertex. |
|
$N |
For VERTEX, specifies a bulge factor (0,1,2) to control the curvature of a vertex blend. |
|
/SETBACK $N |
Specifies the setback length for all edges that meet at a selected vertex. |
|
/AUTO |
For vertex blends specifies that the extent of the setbacks is to be automatically calculated. |
|
/FIX |
Causes the processing of a network of blend attributes by selection of an edge or vertex as specified. |
|
/LOCAL |
For edge blends, used to fix an edge that is not part of a closed network. |
|
/DELETE |
Deletes the selected edge or vertex attributes. |
|
/INQUIRE |
Lists the selected edge or vertex attributes. |
|
/SURFACE |
Specifies that the blend is to be created as a separate surface. No attempt is made to combine it with the original object. |
