PrefaceCATIA Version 5 FreeStyle Sketch Tracer is a new-generation tool used to import stylist'sdrawings into the 3D world.

Using this product you can convert 2D images into a 3D scene to create 3D geometry fromyour hand drawings, or other source such as pictures. You position the 3D model in relation tothe sketch and, in conjunction with other CATIA products, create geometric outlines directlyover the sketches.

The CATIA - FreeStyle Sketch Tracer User's Guide has been designed as an aid to using theFreeStyle Sketch Tracer by itself, but also in conjunction with other CATIA Version 5 FreeStyleproducts or any other CATIA workbench.

If you wish to use the whole screen space for the geometry, remove the specification tree clicking offthe View -> Specifications menu item, or using the F3 key.You could also directly choose Designer Workbench from the Start menu. It would automatically open anew CATProduct document, provided there already is a CATIA session running.



Importing a SketchThis task shows you how to load a sketch into CATIA.

A CATProduct must be open and the FreeStyle Sketch Tracer workbench active.

Click the Create an Immersive sketchicon .1.

The Image File Selectordialog box pops up intowhich you can navigate toopen the sketch you wish.

Here, navigate to theSamples directory andselect theSampleCar1_side.TIFimage.

Importing Sketches


Positioning in 2D ModeThis task shows you how to define the position a sketch according to a cylindrical view: front, top, bottom or sideview within the document.A image has been loaded as described in Importing a Sketch.

From the Sketch Parameters dialog box,choose the Set cylindrical view icon.

1.

The loaded image looks like this:

The displayed axis-system allows you to define the document's origin.

2D Positioning


Move the pointer over the axis-system's middlepoint.A manipulator is displayed and the pointerturns into a hand.

2.

Use the standard CATIA manipulations(translation, rotation, and so forth) to positionthe main axis-system at the correct location.

3.

Release the axis-system's middle point whenyou are satisfied with its position.

4.

Move over to one of the frame's corner.5.

Using the manipulators, you can rotate or zoom the positioning frame, depending on the selectedarrow.

Increasing/decreasing length RotatingWith the pointer still over the size manipulator,right-click, and choose the Edit contextualmenu item.

6.

The Tuner dialog box is displayed,allowing you to enter exact values, inrelation to the document's origin.

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

2D Positioning


The Relative option is used to positionthe frame corner in relation to the imageaxis-system's origin. In this case you canchoose to work in True Length mode, i.e.the value you enter corresponds to thelength between the axis-system's originand the defined point.

The Reset Origin button enable to switchthe reference origin to the currentlocation of the manipulated frame corner.

Once the Relative Origin has been set,you can still manipulate the frame. Asymbol and the Relative Origin textindicate the origin location.

Click the Flip text to invert the axis orientation, and therefore the frame. (See also Copying/Pasting aSketch.)

7.

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, theimage will be cropped to this size.

8.

Once you are satisfied with both the image sizeand the frame positioning, click OK in thedialog box.

8.

A Painting feature is added to thespecification tree.

You can now manipulate the image asany 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 alsochoose 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 Viewpointcontextual menu.
