SolidWorks Session 1 Ferdowsi University of Mashhad Dr. Behnam Moetakef Imani Winter 2011

SolidWorks –a feature-based, –history-based, –associative, –parametric –3D CAD program

“Feature-based” modeling means –build the model by incrementally identifying functional shapes and applying processes to create the shapes –Many different feature types in SolidWorks enable you to create everything from the simplest geometry to more complex artistic or organic shapes. –most common features

SolidWorks is also history based –a panel to the left side of the SolidWorks window called the FeatureManager –FeatureManager keeps a list of the features in the order in which you have added them –enables you to reorder items in the tree (in effect, to change history) –the order in which you perform operations is important

1. Create a sketch. 2. Extrude the sketch. 3. Create a second sketch. 4. Extrude the second sketch. 5. Create a third sketch. 6. Extrude Cut the third sketch. 7. Apply fillets. 8. Shell the model. FeatureManager design trees

Sketching with Parametrics –Sketching is the foundation that underlies the most common feature types. –sketching in parametric software is vastly different from drawing lines in 2D CAD SolidWorks sketches are parametric –you can create sketches that change according to certain rules, and – maintain relationships through those changes –It extends beyond sketching to all the types of geometry you can create in SolidWorks –Creating sketches and features with intelligence is the basis of the concept of Design Intent

SolidWorks has three main data type files: –parts, –assemblies, and –drawings

Terminology: Basic Geometry Face – The surface or “skin” of a part. Faces can be flat or curved, can be analytic or parametric Edge – The boundary of a face. Edges can be straight or curved, can be analytic or parametric Vertex – The corner where edges meet Vertex Edge Faces

Terminology: Basic Geometry Face Edge Vertex Surface Curve Point Topologic VariableGeometric Variable Relations of Geometric Variables Representation of geometric Objects

View Control Magnify or reduce the view of a model in the graphics area. Zoom to Fit – displays the part so that it fills the current window. Zoom to Area – zooms in on a portion of the view that you select by dragging a bounding box. Zoom In/Out – drag the pointer upward to zoom in. Drag the pointer downward to zoom out. Zoom to Selection – the view zooms so that the selected object fills the window.

Display Modes Illustrate the part in various display modes. Wireframe Hidden lines Visible Hidden Lines Removed ShadedShaded Without Edges

Standard Views Isometric View Top View Back ViewLeft ViewFront ViewRight View Bottom View

View Orientation Front Right Bottom Isometric Top Left Back Normal To (selected plane or planar face) Changes the view display to correspond to one of the standard view orientations.

View Orientation The views most commonly used to describe a part are: –Top View –Front View –Right View –Isometric View Viewing the model or drawing through one, two, or four viewports Link view ?

Default Planes –Front, Top, and Right Correspond to the standard principle drawing views: –Front = Front or Back view –Top = Top or Bottom view –Right = Right or Left view

Isometric View Displays the part with height, width, and depth equally foreshortened. –Pictorial rather than orthographic. –Shows all three dimensions – height, width, and depth. –Easier to visualize than orthographic views.

Selection Methods Highlighting Select Entity Box Selection Cross Selection Invert Selection Select Loop Select Chain Selection Filter Tangent Selection

Creating a 2D Sketch 1.Click Sketch on the Sketch toolbar. 2.Select the Front plane as a sketch plane. 3.Click Rectangle on the Sketch Tools toolbar. 4.Move the pointer to the Sketch Origin.

Creating a 2D Sketch 5.Click the left mouse button. 6.Drag the pointer up and to the right. 7.Click the left mouse button again.

Adding Dimensions Dimensions specify the size of the model. To create a dimension: 1.Click Dimension on the Sketch Relations toolbar. 2.Click the 2D geometry. 3.Click the text location. 4.Enter the dimension value. 2D geometry Text location
