Preface

Preface CATIA Version 5 FreeStyle Sketch Tracer is a new-generation tool used to import stylist's drawings into the 3D world. Using this product you can convert 2D images into a 3D scene to create 3D geometry from your hand drawings, or other source such as pictures. You position the 3D model in relation to the sketch and, in conjunction with other CATIA products, create geometric outlines directly over the sketches. The CATIA - FreeStyle Sketch Tracer User's Guide has been designed as an aid to using the FreeStyle Sketch Tracer by itself, but also in conjunction with other CATIA Version 5 FreeStyle products or any other CATIA workbench.

2D Positioning

2. Move the pointer over the axis-system's middle point. A manipulator is displayed and the pointer turns into a hand. 3. Use the standard CATIA manipulations (translation, rotation, and so forth) to position the main axis-system at the correct location. 4. Release the axis-system's middle point when you are satisfied with its position.

5. Move over to one of the frame's corner. Using the manipulators, you can rotate or zoom the positioning frame, depending on the selected arrow.

Increasing/decreasing length 6. With the pointer still over the size manipulator, right-click, and choose the Edit contextual menu item. The Tuner dialog box is displayed, allowing you to enter exact values, in relation to the document's origin.

This let's you define the model's size.

file:///E|/WWW/FmoCXR5/FskEnglish/fskug.doc/src/fskugbt0201.htm (2 of 4) [10/26/2000 3:05:48 PM]

Rotating

2D Positioning

The Relative option is used to position the frame corner in relation to the image axis-system's origin. In this case you can choose to work in True Length mode, i.e. the value you enter corresponds to the length between the axis-system's origin and the defined point. The Reset Origin button enable to switch the reference origin to the current location of the manipulated frame corner.

Once the Relative Origin has been set, you can still manipulate the frame. A symbol and the Relative Origin text indicate the origin location.

7. Click the Flip text to invert the axis orientation, and therefore the frame. (See also Copying/Pasting a Sketch.) 8. Move the pointer over the green dot, in a corner of the image bounding box. A manipulator is displayed. Use it to set the imported image size. When clicking OK in the dialog box, the image will be cropped to this size.

8. Once you are satisfied with both the image size and the frame positioning, click OK in the dialog box.

A Painting feature is added to the specification tree. You can now manipulate the image as any element into a .CATProduct or .CATPart document. Click on the Focus Off text at the bottom of the image to reset the image parallel to the screen. You can also choose the Activate Viewpoint contextual menu. Once you have clicked this text, it changes to Focus On and lets you zoom or move (grabbing the red triangles) the image within the document, independently of the compass. To return to standard document manipulations, click the Focus On text, or choose the the Deactivate Viewpoint contextual menu.

Refreshing an Imported Sketch

Refreshing an Imported Sketch This task shows how to refresh an image, that is update the document into which it has been imported when the sketch has been modified outside CATIA. Open the CarSideView.CATProduct document from the Samples directory and select Designer Workbench from the Start -> Infrastructure menu. 1. Double-click the image name from the specification tree (Painting.1). The Sketch Parameters dialog box is displayed, containing the imported image's name and location path.

2. Click the Reload Image file icon from the dialog box. The image is updated taking into account modifications done outside CATIA. 3. If needed, re-position the frame on the new image. 4. Click OK to save this new image within the Painting.x feature.
