Chapter 4. Advanced Intersect and Follow Me Techniques The Follow Me and Intersect tools are used together frequently to create complex 3D objects. Follow Me is used to create individual objects by extruding a face along a path, and the Intersect tool is then used to get edges where the Follow Me objects meet themselves or other objects. After these intersection edges are created, trimming is easy. This chapter offers some advanced techniques for using them in tandem as well as separately. Specifically, you’ll learn to do the following. Figure 4-3. Figure 4-3 The solution is to create a temporary face on which to draw the Follow Me face. After the Follow Me is complete, you can easily remove the temporary face.
In this recipe’s first example, you’ll start with the model shown in and use Follow Me to make a jewelry box with a rounded top. Adding a notch in the box will give you a temporary face for the Follow Me face; you can fill in the notch after the top is rounded. The second example starts with a round object and ends with a round casserole dish with a rounded lid. You’ll get there by creating a temporary face from one of the object’s straight segments. Want to Create This Model Yourself?
There are two ways to create a box like this. One method is to draw the basic rectangle in Top view, and draw arcs in each corner. When the arc preview is magenta, you know it is equidistant from the corner along both edges. Trim the corners to make a rounded rectangle and then pull it up. Alternately, you can draw a rectangle and pull it up.
Then draw arcs in each corner of the top face, and use Push/Pull to push each arc face down to the bottom of the box. Draw a rectangle on the top or front face and push the rectangle inward, making a small notch. Note If you work with round objects often or hide objects often, it’s helpful to create a keyboard shortcut for the View→Hidden Geometry toggle. I prefer the Function keys (F1, F2, and so forth) for all display commands, which also include Wireframe, X-Ray, and so on.
Setting up shortcuts can be done via the Preferences window. Use Push/Pull with the Ctrl/Option key to pull out one of the segments. One of the vertical faces created by this operation will be used to create one of the Follow Me faces. Figure 4-10. Figure 4-10. Erase all new faces except for one vertical face on the inside and one vertical face on the outside.
Draw a small half-circle face on the outside vertical face (shown in in yellow) and a tall arc (shown in orange) on the inside vertical face. The orange face will be used to create the lid, and the yellow face will be used to create the lip around the bottom of the lid. Trim the rest of the temporary vertical faces. If you paint your new faces, be sure to paint both the front and back face, to ensure that the colors will show even if the Follow Me operation reverses the faces. Figure 4-19. Figure 4-19. Make the circle any size you want and be sure to align it to the red or green axis. To make it easier to copy the round object to other corners later, paint the rounding face a different color (shown in in cyan).
Because it’s hard to know which side of the rounding face will appear after Follow Me, you should paint the back face too. The easiest way to do this is to right-click on the painted face and choose Reverse Face.
(This switches the back and front faces.) Paint the reversed face the same color you just used for the first side. Now this face is painted on both sides. Figure 4-25. Figure 4-25 It you were to make a round object for the corner now, using the technique from, the top face of the table would be broken by the top face of the Follow Me object. To protect the existing faces of the table, you need to use a group. Activate Select and double-click one of the vertical end faces of the pulled rounding faces. This selects both the face and its surrounding edges.
Right-click on the face and choose Make Group. The face will then appear with bold edges and surrounded by a bounding box. Figure 4-26. Figure 4-26. The next step is to draw the Follow Me circle, and it is important that the circle have the correct number of sides. Because this model is based on a hexagon, the number of circle sides should be divisible by six. This ensures that the segments of the circle, and therefore the segments of the resulting round corner, will align with the edges of the Push/Pull faces. Activate Circle and make sure the number of sides is a multiple of six (24 is a good number).
As you did for the rectangular table, place the center directly above the corner of the table. Do not click yet to complete the circle. Note You can set the number of sides of a circle by entering the number before you place the circle’s center point. After you place the center, you can still change the number of sides by typing 24s either before or right after clicking the point along the radius. To establish the radius of the circle, click on any point along the top edge of the group. This ensures that a circle segment will start just above the group, so the round Follow Me object will align perfectly with the Push/Pull objects. Figure 4-29. Figure 4-29.
While the group is still open for editing, run Intersect with Model on the whole group. This creates edges where the group meets the rest of the table. If there are any edges that aren’t created but should be, trace them manually. This is easiest to do with the rest of the model displayed, which can be set in the Components page of the Model Info window. Be sure to check that all edges are drawn, including those on the top and bottom faces of the rounding object.
While the component is still open, open the Components page of the Model Info window to hide the rest of the model, and trim away the extra portions of the group. Discussion The problem discussed in this section deals with different Follow Me faces that are extruded around edges of the same shape. In these cases, you might have difficulty selecting a path in advance, particularly if edges are broken by other operations. The solution is to copy a set of edges elsewhere so that they can be easily selected.
Another problem encountered in the same model is that two sets of Follow Me faces within the same closed shape can interfere with one another. The solution here is to temporarily move one of the faces away, run Follow Me on it, and then move it back into place. After all faces are in place, they can be intersected and trimmed.
The main example that will demonstrate these techniques is a skate park, in which two Follow Me faces create the skate ramp and the spectator seating. In, you will see the same technique applied to a picture frame. Note If you don’t want to bother moving up and down, you could have made the arc and step sections into groups. Then you could use the Edit Group method within Follow Me, without having to move anything. But you would have to Explode both groups before intersecting.
You could also make just one of the sections a group. Hide the fence group and run Intersect with Model on the arcs and steps. Then trim away all the extras.
Check in X-Ray or Wireframe mode to be sure all extra edges are erased. Discussion Using extended Follow Me paths results in Follow Me objects that extend past the faces they are supposed to intersect. This ensures that all faces and edges of the Follow Me objects are long enough to intersect, and it makes trimming after intersection easy. The main example uses the extended path technique to create a hot tub with curved walls and steps leading down into the tub.
The paths for both the tub steps and the curved walls extend past the final limits of the tub, so that extra faces are easy to trim. In the section, the same technique will be applied to window frames. Discussion demonstrated how to use grouped reference geometry to create a 3D Follow Me path. This recipe presents another technique for creating a 3D path, in which intersection edges between two objects create the Follow Me path. This technique is helpful in cases where reference geometry is not easy to draw, but you do know the basic 3D parameters of the path.
In this recipe, you will model a pair of glasses. The frame around each lens proceeds along a 3D path, which is the intersection of a partial sphere and the frame shape. In the section, the same technique is used to create a window frame around a curved window. Figure 4-81. Figure 4-81. To prevent the Follow Me frame from breaking the lens, make the Follow Me face a group.
You know that when a face is 2D, you can select it to define its boundary as the Follow Me path. But when the path is 3D, you need to select the Follow Me edges, and not the face. To select the edges bordering this face, double-click the front face of the lens and then Shift-click to unselect the face. This leaves only the edges selected. Run Follow Me on the frame shape group. To remove the little edges throughout the frame, select everything inside the group, right-click, and choose Soften→Smooth Edges. Adjust the sliders until the edges disappear.
