Creating the Metallic Shell
 
 
 

In this lesson, you will create another reference object and apply additional polygon editing techniques that will cloak the building in a metallic shell.

Set up the lesson:

Create a metallic shell for the building:

  1. Press H and use the Select From Scene dialog to select the Building 1 - Glazing object. On the Modify Panel, in the modifier stack, click the (light-bulb icon) to the left of each modifier to turn off the effect of the modifier.

  2. From the menu bar, choose Edit Clone. In the Clone Options dialog Object group, choose Reference and change the name of the object to Building 1 - Metallic Shell.

  3. With the shell object selected, right-click the active viewport and from the quad menu, choose Isolate Selection.
  4. From the Modifier List, choose Edit Poly.
  5. Right-click the Perspective viewport if it is not already active. Zoom, orbit, and pan until the bottom of the building is clearly visible.
  6. On the Selection rollout, click (Polygon) to turn it on.
  7. Select the middle polygon on the bottom of the building. On the Selection rollout, click Grow repeatedly until you have the entire bottom selected. Press Delete to remove the polygons.

    You now need to remove additional polygons to create the window pattern on the building exterior.

Create openings for the front and back of the building shell:

  1. Press Shift+Z repeatedly to undo viewport changes until you can see the entire building again.
  2. In the Perspective view, click Front on the ViewCube, then right-click the ViewCube and from the pop-up menu, choose Orthographic.

    TipIf the ViewCube is not visible in your viewports, from the General viewport label menu (“[+]”) choose ViewCube Show The ViewCube.

    You will be selecting faces on both the front and back of the building, and this is more reliable in Orthographic views. (In a Perspective view, the Perspective projection can cause selection to choose back faces that are out of alignment with the front.)

  3. On the Selection rollout, make sure that Ignore Backfacing is turned off (it is off by default).

    While Ignore Backfacing is off, selecting a face on the front of the building also selects the corresponding face on the back.

  4. Press Alt+W to maximize the viewport.
  5. Turn on (Select Object). Ctrl+click+drag to select a 5x15 grid of polygons in the upper portion of the model, leaving one row of polygons unselected at each edge of the building.

    This selects polygons on both the front and back faces of the model.

  6. Alt+click to remove each corner polygon from the selection, as shown in the illustration. This removes the selected polygons on the front and back faces of the model.

  7. Ctrl+click+drag to select the remaining polygons, as shown in the next illustration. Use the Alt+drag technique to remove polygons from the corners of the window patterns, and the archway of the entrance.

  8. Press Delete to delete all of the selected polygons on the front and back of the building.

    Next, you will remove polygons from the sides of the building, using a slightly different pattern.

Create openings for the sides of the building shell:

  1. Use the ViewCube to change to a Left view of the building.
  2. Select polygons in a pattern of 5x7, 5x15, 5x15, and 5x8, with the corners removed, as shown in the illustration.

  3. Press Delete to delete the polygons.
  4. Press Shift+Z until the viewport shows a perspective view again.

    Next, you will edit the building edges to make them rounded.

Chamfer the corners of the shell:

  1. On the Selection rollout, click (Edge).

  2. In the Perspective view, zoom in to see the shell more closely. Use the ViewCube to rotate the view so you can see all four corners of the shell, whether inside or out.

  3. At one level of the shell, click and Ctrl+click to select the four vertical edges at each corner of the building.

  4. On the Selection rollout, click the Loop button. This selects all four edges of the building in their entirety.
  5. On the Edit Edges rollout, click the Settings button next to the Chamfer button (just to the right of the main button).

    3ds Max Design displays the caddy controls for the Chamfer tool.

  6. On the Chamfer caddy, set the first control, Amount, to 2.0m. This sets the width of the bevel created by the chamfer operation. Set the second control, Segments, to 4. This divides the chamfered region into four segments. The more segments you set, the more rounded the edge will be. Click (OK).

  7. Click (Edge) again to exit the Edge sub-object level.

Give thickness to the shell, and inspect the result:

  1. From the Modifier List, add a Shell modifier and on the Parameters rollout, set the value of Outer Amount to 2.0m.

    This gives the metallic shell a thickness of two meters.

    Now, let’s look at the building with the modifiers applied.

  2. Exit Isolation Mode.
  3. Click Alt+W to view all four viewports again.
  4. On the Modifier Stack, turn on the three modifiers you turned off earlier: FFD, Twist, and Taper.

  5. In the Perspective view, click (Zoom Extents Selected).
  6. Click an empty area of the viewport to deselect the building.

    The modeling phase of the building is now complete. Next, you will add materials to the building exterior.

Apply materials to the building:

  1. Press H and on the Select From Scene dialog, highlight the Building 1 - Glazing object, and then click OK.

  2. On the main toolbar, click (Material Editor) to open the Slate Material Editor.
  3. On the Material Editor menu bar, open the Options menu and turn off Propagate Materials To Instances.
  4. In the Sample Slots section of the Material Editor Browser (on the left), locate the Glass material, then drag it to the View1 window (in the center).

    3ds Max Design asks whether to make this a copy or an instance. Choose Instance, then click OK.

    TipTo navigate conveniently in the Slate Material Editor, enlarge the window from its default size. It also helps to drag the width of the Browser panel to make it wider.
  5. On the Material Editor toolbar, click (Assign Material To Selection) to apply the Glass material to the glazing object.

    3ds Max Design applies the glazing material to the glazing. In the Scene Materials section of the Browser panel, now you can see a Glass entry, and the object name.

    NoteIf Propagate Materials To Instances is on when you do this step, then all of the buildingl is assigned the Glass material.
  6. Press H again, and select the Building 1 - Metallic Shell object.
  7. In the View1 panel, click the Glass material to highlight it, then press Delete.

    This removes the Glass material from the active material view, but doesn’t remove it from the scene.

  8. In the Sample Slots section of the Browser panel, locate the Metal material, and drag it to the View1 panel.
  9. This time drag from the Metal material node’s output socket, the round control at the right,

    Dragging from a material’s output socket

    ... and in the viewport, drop the wire on the metal shell object.

    ... and dropping onto an object

    Dragging and dropping is another way to assign a material.

    NoteYou won’t see the wire as it crosses the panel at the right of the Slate Material Editor, or in the viewport.
  10. Press H again, and select the Building 1 - Mullions object.
  11. In the Sample Slots section on the Browser panel, locate the Mullions material (you’ll have to scroll down), then apply it to the mullions object using the methods described in the previous steps.

    The Mullions material is a matte gray, not shiny like the metallic shell.

  12. Close the Slate Material Editor.

Summary

This tutorial demonstrated how easy it is to quickly visualize architectural concepts using 3ds Max Design. You learned how to build an organically-themed architectural model from simple geometric objects by adding Twist, Taper, and FFD modifiers. You also saw how basic polygon editing techniques can be used to create detailed elements such as mullions, and to round off building corners.
