Step 3: Fitting the Blocking to the Geometry

The block vertices and edges need to be fit to geometry points and curves.

  1. Create a Composite Curve

    Even though curves can be automatically grouped while associating edges to curves, sometimes it beneficial to group them first. One such benefit is the ability to group all curves that tangentially meet (smooth transition at the ends of two adjacent curves).

    In this step, you will group the tangential curves around the base of the hemisphere.

    Blocking > Associate   > Group Curve  

    1. Retain the selection of Group Curves.

    2. Select All tangential for Group.

    3. Click Apply in the Group/Ungroup curves DEZ.

      Note:  This feature needs geometry connectivity. If you had not run build topology, the software will prompt you to do so now.

      All four base curves forming the circular perimeter of the hemisphere will be grouped as shown in Figure 69: Grouped Tangential Curves.

  2. Project Edges to Curves

    Blocking > Associate   > Associate Edge to Curve  

    1. Click   (Select edge(s)) and select the four bottom edges using the left-mouse button. Click the middle-mouse button to accept the selection.

    2. Click   (Select compcurve(s)) and select the grouped circular curve using the left-mouse button. Click the middle-mouse button to accept the selection.

    3. Click Apply in the Associate Edge -> Curve DEZ.

      The selected edges will turn green.

  3. Verify that the correct associations have been set as shown in Figure 70: Projection of Edges to the Associated Curves.

    1. Enable Vertices and display by Numbers, in the display control tree.

       Blocking > Vertices

       Blocking > Vertices > Numbers

    2. Enable the display of Surfaces and select the Solid display.

       Geometry > Surfaces

       Geometry > Surfaces > Solid

    3. Select Show association.

       Blocking > Edges > Show association

    4. Disable Show association before proceeding.

    5. Disable Surfaces before proceeding.

        Geometry > Surfaces

  4. Move the vertices to the curves and surfaces.

    Blocking > Associate   > Snap Project Vertices  

    1. Retain the selection of All Visible for Vertex Select.

    2. Click Apply (Figure 71: Vertices Moved to Geometry).
