Many IDers are not familiar with the surfacing in Solidworks. It might be handy to go through a simple product like a mouse to walk through how you might go about modelling in solidworks. Over the next few days I will go over how to go about doing this in Solidworks.
I sketched this concept over lunch so the design might change over the next few days hehee Hopefully we will have a helpful series

作者: quijote 时间: 2005-5-30 01:13
Here are some approaches that we can possibly take. Approach 1 has the disadvantage of having a degenerate point where all the isoparms come together. This can make the surface quality difficult to control. We will probably have a hybrid of Approach 2 & 3 taken to another level

作者: quijote 时间: 2005-5-30 01:14
This is not the mouse we are planning to model just a quick stand in to show some basic modeling techniques

作者: quijote 时间: 2005-5-30 01:21
Over the next few days, I will try and break down how to make this mouse. It is composed of surfaces that are later knit, shelled and split into various components. This kind of method is what is referred to as a "top down" assembly. The actual construction method turned out to be a variant of Approach 2. My sketch shows a crease in the mouse. I decided not to model it because first it would have taken a little longer to think through and explain and second-it wasnt looking all that good .

作者: quijote 时间: 2005-5-30 01:21
These are the underlying surfaces to model

作者: quijote 时间: 2005-5-30 01:22
The following part deals with inserting backgound bitmaps to use as underlays. Also the curve formed at the interface of the red part and the grey plastic is important. So we will define the character line by means of a 3D curve (3D sketch).

Solidworks uses flat planes called construction planes to create flat curves (2D sketch). These curves are then used to create geometry. The default construction planes are the Right, Front and Top plane. Designers used to Rhino and Alias can be confused by the construction planes. The default constuction planes are not actually views. Refer to Solidworks documentation to learn more to pan, zoom and dolly the camera.

Inserting Background Sketches:
1) Click Right plane.
2) Insert >Sketch, to start a sketch on the Right plane
3) Within the sketch Insert&gt

icture to insert a background sketch. Insert a cropped view of the mouse in the right hand view. I used Photosop to crop out the different views. It is useful to crop each view as close to the bounding envelope as possible.
4) Draw a line that passes through the origin, and dimension the line to 120 mm. This line will be used as a reference to scale the background bitmap
5) Double click the bitmap. Drag handles will appear that will allow you to scale the jpeg to the 120 mm construction line. position the highest point of the sketch over the sketch origin by dragging and dropping

作者: quijote 时间: 2005-5-30 01:23
Repeat the previous procedure on the Front and Top Plane. It is convenient to position the jpegs so that the baseline passes through the origin.

作者: quijote 时间: 2005-5-30 01:24
Sometime it is more useful to have more than one view of the model

作者: quijote 时间: 2005-5-30 01:24
Creating the 3D sketch:

In addition to 2D sketches, SWX allows you to create 3D sketches. which are splines with control points that can move in three axes. They are very useful to define character lines/ bone lines of a product.

1)insert>3DSketch
2)in the right view use the spline tool to trace over the bitmap. It defualts to create a flat curve in the Right Plane.

作者: quijote 时间: 2005-5-30 01:25
Similar to Rhino and Alias you can move the control points in the Top View to match the bitmap. (Hint: Hit Spacebar to get default views like left , right , top etc

作者: quijote 时间: 2005-5-30 01:26
Solidworks Rant Time:
The spline functionality is still not fully implemented. The spline control handles of 3D sketches are VERY buggy unless you constrain them horizontal, vertical or tangent to a construction line.

eventhough you cannot use spline handles to the same degree in 3D that you can in a 2D sketch they are stiil a big leap over 3d splines in 2004. The curves will just be a little heavier because you use control points to define curvature rather than the spline handles

作者: quijote 时间: 2005-5-30 01:26
Tweak the curve to match your sketch lines. You have just defined a 3D character line!

作者: quijote 时间: 2005-5-30 01:27
This is what you should see when you open the file from the beginning of the tutorial. You will see a trimmed surface loft and a bunch of curves. I wanted to start with just curves, but the side section curves are created with curves that are tangent to the trimmed loft surface. The side section curves are also constrained to pierce the 3D character line that we previously created

作者: quijote 时间: 2005-5-30 01:28
Start a Loft between the Edge of the Trimmed Surface and the 2D sketch "

lan View" All required sketches should be in the folder "Sketches for the Main Surfaces" which is nested in the history tree.

作者: quijote 时间: 2005-5-30 01:28
Start editing the loft so that it is curvature continuous at the top. This is done by editing the Start Constraint to "Curvature Continuous" in the drop down menu.

Define the loft a little more with guide curves. This can get a little squirrelly along the center line because the guide curves at the rear and front (Rear Section of Side Profile and Front Part of Side Profile ) along the center-line are cut (convert entities) from the Profile Sketch. Use the secondary history tree in the modeling window to pick the right sketch

To create a smooth connection along the center line click the guide curves and choose Normal to Profile to make the loft smooth along the center line.

作者: quijote 时间: 2005-5-30 01:29
Mirror the surface bodies along the Right Plane. Generally mirroring the bodies (as opposed to Faces or features) is the most straight forward because the computer does not have to calculate too much information

作者: quijote 时间: 2005-5-30 01:29
If at any point the sketches become annoying or too busy CLick View>Sketches to toggle visibility of Sketches. You can do the same thing with planes, curves, origins etc:

I have toggled sketch visibilty so that I can choose the edges of the surfaces to define a planar surface

作者: quijote 时间: 2005-5-30 01:30
Use the bottom edges of the lofts to define the bottom planar surface

作者: quijote 时间: 2005-5-30 01:30
Knit all the surfaces together to create a Solid. Check the box that says "Try to form a Solid" (the process is similar to creating a closed polysurface in Rhino)
This will give the model mass properties and gives you the ability to use solid modelling tools on the model

作者: quijote 时间: 2005-5-30 01:30
Shell the solid to give wall thickness of 2mm. If you click on any faces that will create an opening in the shell because those selected faces will not be included in the final shell. So in this case Dont click on any faces because we are interested in keeping all the surfaces

作者: quijote 时间: 2005-5-30 01:31
Fillet the bottom edge 2mm

作者: quijote 时间: 2005-5-30 01:31
Created an extruded surface with the 2D sketch that defines the material break between the two colored plastics.

This will be used to split the solid body into two bodies along the character line that we defined earlier

作者: quijote 时间: 2005-5-30 01:32
Split the body using the extruded surfaces.

Pick the surface
Cut the part
Pick the Bodies that you want to keep from the resulting bodies

作者: quijote 时间: 2005-5-30 01:33
Go to the Solid Bodies folder and pick the top part of the mouse and hide it

作者: quijote 时间: 2005-5-30 01:33
You can see the wall thickness now that you can see inside. Fillet the top edge. Fillets are cool from an engineering perspective they eliminate stress risers at sharp edges, and allow for easier ejection from tooling. Fillets also make your final renders look good because they catch light well.

作者: quijote 时间: 2005-5-30 01:33
Hide the bottom and fillet the edge of the top component

作者: quijote 时间: 2005-5-30 01:34
Create an extruded surface to split the top component again.

作者: quijote 时间: 2005-5-30 01:34
Split the model with the extrude. In hindsight it would have been better to combine all the splits in to one command

作者: quijote 时间: 2005-5-30 01:35
You can change the color properties of any object by right clicking on it and going to color

作者: quijote 时间: 2005-5-30 01:35
Cut extrude the opening for the mouse wheel. Offset the sketch plane from the sketch plane by about 5mm (this option can be found in the first drop down menu).

作者: quijote 时间: 2005-5-30 01:35
Extrude the mouse wheel and in the Direction1 and Direction 2 options set them to offset from surface. Create the extrude .5 mm offset from the inner walls of the opening. Uncheck the box that says merge result. SWX by default tries to chunk features together into one solid mass whenever Solid features are used. Most times this is preferred but sometimes you might might to makuse of multi- body features (as in the case of the scroll wheel.

作者: quijote 时间: 2005-5-30 01:36
This fillet is a full round fillet. Pick the three consecutive faces of the cylinder to create the fillet

作者: quijote 时间: 2005-5-30 01:37
此楼无语

作者: quijote 时间: 2005-5-30 01:37
I figured out how I wanted the ribs to look like in the sketch in the folder "Rib sketches" Extrude a surface that goes past the outer surface of overmold

作者: quijote 时间: 2005-5-30 01:38
This creates a rib that you can lay onto the surface of the overmold

作者: quijote 时间: 2005-5-30 01:39
Create a 3D sketch and create intersection curves between the surface extrude and the outer surface of the overmold.

(Hit Esc after you create the curves to back out of the intersection command)

作者: quijote 时间: 2005-5-30 01:39
The curves in green are the curves on the surface of the overmold that you want to map your gripping ribs to. as you can see there are four ribs to be mapped by means of the deform tool.

So we will have to make copies of the revolve.

原站图片错误

作者: quijote 时间: 2005-5-30 01:40
Use the Copy/move Body Feature to make 3 copies of the revolve. Do not specify a displacement (all the copies will overlap and look like one revolve even though there are 4 bodies). This is so that we can use the centerline of the Revolve sketch as an initial curve
(Ignore the surface extrude . You can hide it)

作者: quijote 时间: 2005-5-30 01:40
The Deform tool uses curves to map your geometry to curves. The initial curves map to your geometry, and then Solidworks interpolates the change in geometry from the change between the Initial and Target Curves

又出错

作者: quijote 时间: 2005-5-30 01:40
When you are performing the deform command, hide all the revolved bodies except for one. This makes it easy to select the body you want to work on.

As you can see in the tree, there are 4 deforms performed t omodel each rib

作者: quijote 时间: 2005-5-30 01:41
Mirror the grippy bodies to the other side

作者: quijote 时间: 2005-5-30 01:42
Combine all the grey parts into one Solid body

作者: quijote 时间: 2005-5-30 01:42
Renszu-Photoworks does have the capability of z-depth rendering. Here is a progression to give you an idea of what Rensu was talking about Norah. You can even uses the raw render below and the depth cue rendered image to approximate DOF. As you can see you dont really have to go to the effort of doing a depth cue render if you already have a picture in your minds eye of what is farthest and nearest to the viewer

LIke Ive said before-Photoworks is not the best rendering system by any means but it can do decent stuff
