Car Trim

Trim - Grill - Page 1

 

The grill is not overly complicated to model, just a little tedious. Now that I've built up your excitement sufficiently, we can get down to it! Just like the rest of the trim we are doing, this is a good exercise in using existing geometry to begin working on other objects.

 

Let's go back to the grill area that we defined earlier and use some of the points.

In point mode, select the points that define the outside edges of the lip face. (The lip face being forward facing surface of the bordering rim around the opening...)

 

 

 

Using the structure manager, copy these points and paste them into a new polygon object. This picture is difficult to discern, but it is just showing 8 pairs of points floating in space... trust me! :-)

 

Using the bridge tool, create polygons between these point pairs so that we basically have a duplicate surface of the original lip face.

Select all the polygons and make sure all polygon normals are facing forward (toward the front of the car).

 

From there, you should be able to perform a 'Bevel' operation on the selected polygons. Basically this extrudes the polygon shape back around the lip of the grill opening while increasing the thickness of this grill border trim. Afterwards, select all polygons and make sure the normals are aligned and facing outwards.

 

Now, inevitably we toss this object underneath a HyperNURBS parent, and will also add a symmetry object in just a minute... but to prepare the object for symmetry, we need to select the end polygons (that would be the two polygons as shown that will be closest to the plane of symmetry).

 

 

Delete these polygons to open the ends of the trim up.

Next, select the points that define the edges of these ends and set the X value of these points to zero.

 

 

Once the end points are zeroed along the X axis, the object can be made symmetrical and should have a flawless transition across the plane of symmetry.

 

Now make the car front visible again and get ready to adjust this trim! We'd like it to fit the edge of the grill opening a little better, and the best way to make sure it will is by using point manipulation.

Select the inner row of points on the back edge of the bevel.

 

Move these points into position such that the inner surface of the trim becomes a wide, flat strip that encircles the grill opening more accurately. The extra depth on the inner surface is mainly for aesthetic reasons... (I felt like it!) ;-)

 

 

This shot shows the inner trim surface being affected by an 'extrude inner' operation. This is to sharpen the edges of the grill border trim where it makes the transition from the outward facing lip to the inner surface.

 

Once an extrude inner is performed on a polygon object under symmetry, it will create extraneous polygons along the plane of symmetry. These should be deleted and the corresponding edge points must be zeroed using the Set Value command on the X axis. The gaps left by polygon deletion should close up.

 

The end result, hopefully, is a border that follows the shape of the grill opening we had modeled before.

And it will look even better once it's done up in chrome!

 

Now it's time to move onto the part of the grill that looks like a grill. Mainly the, uh...grill. ;-)
