DESIGN AND ASSEMBLY OF PREDATOR YATCH WITH PHOTO REALISTIC RENDERING USING SOLIDWORKS

 

OBJECTIVE

The main objective of this project is to understand the basics of SOLIDWORKS surface modeling and assembly by designing and assembling of Predator Yatch and also creating Photo realistic rendering.

 

INTRODUCTION

Computer aided design (CAD) is the method of using a computer with CAD software for design and drafting applications. CAD has taken the place of manual drafting. The drafter or designer creates a   3-D model or 2-D engineering drawing of a part using CAD Software

The SOLIDWORKS CAD software is a mechanical design automation application that lets designers quickly sketch out ideas, experiment with features and dimensions, and produce models and detailed drawings.

 

DESIGN INTENT

It determines how your model should behave as a result of the changes made to the model. For instance, if you make a boss with a hole in it, the hole should move along with the boss, whenever it is moves.
                                              

                                      

 

WORKING WITH SURFACES

 

With surface modelling, can build a shape face by face. Faces made by surface features can be knit together to enclose a volume, which can become a solid. With solid modelling, can build many faces at once in a single feature to make the volume. In fact, solid modelling is really just highly automated surface modelling. Obviously, there’s more detail to it than that, but this definition will get you started.

can drive a car without knowing how the engine works, but you cannot get the most power possible out of that car by only pressing harder on the gas pedal; you have to get under the hood and make adjustments with an understanding of how it works. In a way, that is what working with surfaces is really all about—getting under the hood and tinkering with the underlying functionality.

The goal of most surface modelling is to finish with a solid. Some surface features make faces that will become faces of the solid, and some surface features only act as reference geometry. Surface modelling is inherently multibody modelling because most surface features don’t merge bodies automatically.

 

INTRODUCING SURFACES

In the end, you may never really need surfaces. You can perform workarounds using solids to do most of the things you need to do. However, many of these workarounds are inefficient, cumbersome, and raise as many difficulties as they solve. Although you may not view some of the typical things you now do as inefficient or cumbersome, after you see the alternatives, you may change your mind. The goal for this chapter is to introduce surfacing functions to those of you who don’t typically use surfaces. I’m not showing how surfaces are used in the context of creating complex shapes—just how you can use them for various general 3D modelling tasks.

The word surfacing has often been used (and confused) to signify complex shapes. Not all surface work is done to create complex shapes, and many complex shapes can be made directly from solids. Many users think that because they don’t make complex shapes, they never need to use surface features. This chapter shows mainly examples that don’t require complex shapes, in situations where surfaces make it easier, more efficient, or simply possible to do the necessary tasks. Although some of the uses of surfaces may not be immediately obvious, by the end of this chapter, you should have enough information and applications that you can start experimenting to increase your confidence in surfacing techniques. Many surfacing techniques have some sort of equivalent or analogue in the solid modelling world, but not all. When the analogue does exist, I’ll share it to help you understand the function of specific surfacing tools.

 

UNDERSTANDING SURFACING TERMINOLOGY

When dealing with surfaces,   may hear different terminology from the terminology typically used with solid modelling. This special terminology also often exists for surfaces because of important conceptual differences between how solids and surfaces are handled.

These terms are fairly universal among all surfacing software. The underlying surface and solid construction concepts are generally uniform between the major solid and surface modelling packages. What varies from software to software is how the user interacts with the geometry through the software interface. You may never see some of these terms in the SolidWorks menus, Help files, training books, or elsewhere, but as you use the software, you’ll see why the concepts are relevant.

 

HYBRID MODELLING

The term hybrid modelling can take on a lot of different connotations. can have a mix between solid and surface, surface and subdivision, history and direct. So be careful when using the term; it means different things to different people. In this case, I’m using it to mean a combination of solid and surface modelling.

Surface modelling tends to be slower than solid modelling. model each face individually and then manually trim and knit. Cutting a hole in a surface model is much more involved than cutting a hole in a solid. To cut a hole in a surface model, you first trim a hole on one side, then the other side, then make the cylindrical face of the hole, and then knit together the new and old faces as a single, enclosed volume.

Solid modelling is essentially highly automated surface modelling; however, as any software user knows, automation almost always comes at the expense of flexibility, and this situation is no different. Surface modelling puts the compromised power back into your hands, and that’s really why we take the time to learn it.

Solid modelling strengths are predisposed to a type of part with square ends or a flat bottom because solids are creating all sides of an object at once, and capping off a solid feature with a domed shape is difficult. For example, think about an extrusion: Regardless of the shape of the sketch, you have two flat ends. Even lofts and sweeps typically end up with one or two flat ends because the section sketches are often planar. Surfaces enable you to create one side at a time. Another way of looking at it is that using surfaces requires you to build parts in sections. Sometimes, you’ll find that, even with prismatic modelling, surfacing functions are extremely useful. I don’t propose that you dive into pure surface modelling just to benefit from a few of the advantages, but I do recommend that you consider using surface techniques to help define your solids when appropriate. This hybrid approach is sensible and opens up a whole new world of capabilities. I have heard people say after taking a SolidWorks surfacing class that they would never look at CAD geometry in the same way again

 

SURFACING TOOLS

Surface feature equivalents are available for most solid features such as Extrude, Revolve, Sweep,

Loft, Fillet, and so on. Some solid features don’t have an equivalent, such as the Hole Wizard, Shell, and others. Several surface functions don’t have solid equivalents, such as Trim, Untrim, Extend, Thicken, Offset, Radiate, Ruled, and Fill.

 

USING BOUNDARY SURFACE

The Boundary Surface feature was created as a higher-quality replacement for the Loft feature, but certain limitations mean that Loft has not been removed from the feature list. The Boundary Surface feature most resembles a loft, but it has elements of the sweep and fill. Loft also does a few things that Boundary cannot, such as a closed loop loft without a direction 2 curve, and most importantly, a centreline loft.

 

USING THE OFFSET SURFACE

The Offset Surface feature’s closest relatives are the Thicken feature and the Sketch Offset. It may also fail for the same reasons. For example, if you offset a .25-inch radius arc by .3 inches to the inside, it will fail because it cannot be offset up to or past a zero radius. The same is true of offsetting surfaces. Complex surfaces don’t have a constant curvature; they’re more like a spline by having a constantly changing curvature. If the offset is going in the direction of decreasing radius and is more than the minimum radius on the face or faces being offset, then the Offset Surface feature will fail.

 

USING KNIT SURFACE

The Knit Surface functionality was discussed previously in the “Understanding Surfacing Terminology” section as well as in the “Using Radiate Surface” section. If the knit operation results in a watertight volume, the Try to Form Solid option turns the volume into a solid. You can also make a solid from a surface using three other functions. The Fill Surface feature has an option to merge the fill with a solid or to knit it into a surface body; if the knit surface body is closed, then it gives you the option to make it a solid. This is a very nice, complete interface design, with options that save you many steps. The Fill Surface feature is described in more detail later in this chapter.

Create Solid is available only when you use Knit Surface or Fill Surface. Whenever you want the surface to become a solid body using Fill or Knit Surface, Create Solid highlights but remains inactive until all the surfaces are merged together and create a closed volume. Create Solid only highlights when you check Merge Result.

 

USING THICKEN SURFACE

The other function that also creates a solid from a surface is the Thicken feature. If a surface body that encloses a volume is selected, then the option Create Solid from Enclosed Volume appears on the Thicken Property Manager, You can access the Thicken feature by choosing Insert ➢ Boss/Base ➢ Thicken from the menus.

 

USING PLANAR SURFACE

Planar surfaces can be created quickly and are useful in many situations, not just for surfacing work. Because they are by definition planar, you can use them to sketch on and for other purposes that you may use a plane for, such as mirroring, cutting, or dimensioning

 

USING EXTEND SURFACE

The Extend Surface feature functions in much the same way that the Extend function works in sketches. However, spline-based surfaces are more difficult to extend than sketch entities.

 

USING TRIM SURFACE

The Trim Surface feature was described briefly earlier in this chapter, but it warrants a more complete description here. Surfaces can be trimmed by three types of entities:

 Sketches

 Planes

 Other surfaces

When you use surface bodies to trim one another, you have two options: Standard or Mutual Trim. The Standard option causes one surface to act as the Trim tool and the other surface to be trimmed by the Trim tool. When you select the Mutual Trim option, both surfaces act as the Trim tool, and both surfaces are trimmed.

 

The Fill Surface feature is referred to by the SolidWorks interface and documentation as either Fill or Filled, depending on where the reference is made. In my opinion, it is one of the most powerful tools in the surface modeler’s toolbox. It is sometimes amazing what this feature can do. The Fill Surface feature is intended to create oddly shaped holes between surface bodies. You can use constraint curves to drive the shape of the fill between the existing boundaries. It can even knit a surface body together into a solid, all-in-one step. Beyond this, you can use Fill Surface directly on solid models and integrate it directly into the solid automatically (much like the Replace Face function, which is described later in this chapter). While in development, it was referred to as an N-sided patch.

 

USING RULED SURFACE

Ruled surfaces are discussed in general in the section “Understanding Surfacing Terminology.” Here, I discuss the topic in more detail, specifically with regard to the SolidWorks interface for creating ruled surfaces.

The Ruled Surface feature in SolidWorks is one of those features that you may never miss

until you see it in action. It’s extremely useful for constructing faces with draft, extending faces tangent to a direction, making Radiate Surface types, building molds, and many other applications. It can also be frustratingly unreliable.

RADAR

Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect  aircraft, ships, space craft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microw waves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s). Radio waves (pulsed or continuous) from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed.
