77 The view is newly positioned.

78

79 Setting View Relative Positioning The purpose of this task is to re-position a Generative view relatively to Generative or Interactive elements (a line/callout, a point or the frame of a view). You need to open a 3D Part and generate projection views as well as an isometric view. Open the GenDrafting_part.CATPart document from the /online/samples/gendrafting directory. 1. Right-click view to be re-positioned, for example an isometric view. 2. Select the Set relative position option from the displayed contextual menu. A direction positioning line appears that is related to the isometric view. This isometric view can be positioned as desired and relatively to the front view. Note that the isometric view is assigned anchor points. 3. Select the direction positioning line end black square point. Once you have clicked the end square point, this point becomes a blinking red end point and remains so until you select a line. You can also click the direction positioning line. In this case, the positioning line becomes a blinking line and remains so until you select a line (callout line).

80 4. Click the edge according to which you want the isometric view to be aligned. 5. Click one anchor point, for example, the bottom left one. The view anchor point aligns to the green point and thereby to the direction positioning line.

81 Note that you may also select the front view frame and align the isometric view to the front view according to the barycenter. 6. Using the green point, you can rotate the isometric view around the front view.

82 7. Using the direction positioning line, translate the isometric view along the direction line and locate it at the desired distance. If you happen to modify the length of the direction positioning line, this new length will be kept whatever positioning modifications you may apply to the isometric view. Note that if you had previously positioned this isometric view according to a point, not only the line length but also the line angle will be kept. For leaving view relative positioning, click in the free space. Each time the cursor comes near the direction positioning line, the position and length coordinates of this line appear. As you use relative positioning, do not try to move the view outside of the anchor point frame. If you do so, you will leave view relative positioning. Additional Positioning: You can also perform the following: Align a view relatively to one edge of this view.

83

84 Locking a View CATIA provides the capability to lock views via the Edit->Properties commands. It might be interesting for you modify the part without modifying the generated views.

113 About Dimensions Generation This section provides the relevant information you need when performing dimensions generation, whichever the command you activate to do so. In other words, the rules described in the following section are valid either when performing a Dimension Generation in one Shot or a Semi-Automatic Dimension Generation. Now make sure, you customized the Dimension Generation settings via the Tools/options/Drafting/Generation. The generated dimensions are positioned according to the views most representative. In other words, a dimension will appear on a view so that this dimension needs not be also created on another view. The generated dimensions will be positioned according to the following criteria: 1. on the view on which the dimension may be generated. 2. on the view on which the dimension is better visualized. For example, a view on which elements are visualized in non-hidden lines instead of hidden lines. 3. on external views. For example on projection views instead of detail or section views. 4. on the view with a bigger scale. 5. on views including more dimensions. 1. If needed, modify the 3D part, for example, modify a constraint. 2. Click icon. The dimensions are generated on the views on the condition the settings were previously switched to the dimension generation option. For this, go to Tools/Options/Drafting (refer to Customizing the Dimension Generation What About the Dimensions that may be Generated from Constrained 3D Elements? To make sure the dimensions you need to handle in your session are those expected, here is a list presenting the constrained 3D elements and the resulting associated dimensions after generation. Constrained 3D Elements Generated Dimension Types Sketcher All dimensions: angle, distance, radius, diameter 3D part Angle, distance Features: The dimensions below:

116 Filtering Dimension Generation This task will show you how to set filters before or after (Tools/Dimension Generation) dimension generation using the Filter dialog box. Open the GenDraftingDimGeneration.CATPart document from the online/samples/gendrafting directory. You will then create views from this part. The default filter dialog box displayed means the generated dimensions refer to at least one generated element. If you checked the Generate all dimensions button, you obtain the maximum number of dimensions even if they are not associated with generated elements. The highlighted dimension represents a sketcher constraint, for example an Offset between two points, even if the points are not visible in the drawing.

117 Let's describe the dialog box more precisely: Generate all dimensions: generates dimensions even if they are not associated with generated elements. Sketcher wireframe constraints: generates dimensions from Sketcher wireframe constraints even if they are not associated with generated elements. 3D wireframe constraints: generates dimensions from 3D wireframe constraints (for instance an Offset between two planes) even if they are not associated with generated elements. Measured Dimensions: generates dimensions from measured constraints. Design Tolerances: applies the constraint tolerances to the corresponding generated dimension. : This icon allows to recover the excluded constraints. You need to select the constraints in the 3D Tile your window horizontally to visualize at the same time your drawing and the related part(s). In the default settings, this dialog box is not displayed at the end of dimension generation unless you specify it using the Tools->Options menu items. For more information please refer to Customizing Dimension Generation.

118 Note that you can perform dimension generation within the views of your choice. What you need to do is just select them. CATIA automatically highlight the selected views.

119 Analyzing Dimensions This task will show you how to perform an analysis via the Analysis dialog box. You can either perform the analysis before or after the dimension generation. The Generated Dimensions Analysis dialog box is used to highlight the dimensions in the drafting sheet as well as the associated 3D constraints you can visualize in your Part or Product Document. The Dialog box displays information about: Constraints Contraints associated with generated dimensions: note that if you select a dimension, the corresponding constraint is highlighted in the 3D and conversly. Other constraints: constraints not associated to generated dimensions. Excluded constraints: constraints not taken into account during the dimension generation. You previously excluded them using the icon.

120 Dimensions New Generated Dimensions: allows to identify new generated dimensions since your last dimension generation. Generated Dimensions: displays all generated dimensions. Other Dimensions: displays dimensions created via the Interactive Drafting workbench. In the default mode, this dialog box is displayed at the end of dimension generation unless you specify this via the Tools->Options menu items. For more information please refer to Customizing Dimension Generation.

121 Dimension Generation in One Shot This task will show you how to generate dimensions in one shot from the constraints of a 3D part.

In other words, a dimension will appear on a view so that this dimension needs not be also created on another view.

123 Semi-Automatic Dimension Generation This task will show you how to generate dimensions step by step from the constraints of a 3D part. Only the following constraints can be generated: distance, length, angle, radius and diameter. You need to open the Carter_Document.CATPart and, in this particular case, to manually create constraints from this part. You will then create views from this part. Note that in this task you will only use the Front View. Constraints may be of three kinds: created manually (i) via the sketcher or (ii) via the 3D part, or (iii) automatically created via internal parameters. 1. Make sure the Dimension Generation settings are in the default mode as shown opposite: Select Tools->Options->Drafting->Generation/Dimension Generation (please refer to Customizing the Dimension Generation ) 2. Click the Generating dimensions step by step icon. The Step-by-step generation dialog box displays and will remain displayed until the end of the generation. 3. Check the Visualization in 3D button to see the constraints corresponding to the dimensions to be created on the views. 4. Check the Timeout button. The default timeout is set to 2 seconds. Enter the timeout value you need for example, 3 seconds. 5. Click to start the dimension generation. Now, you might need to pause the generation for modifying the dimension position for example.

124 6. Click. The generation is paused. 7. Select the dimension to be modified. 8. Drag the dimension to its new position. Note that, at this step (pause), you can perform all kinds of modifications before the dimension generation. You want one particular dimension not to be generated on the view: click. The constraint is automatically excluded and the dimension will not generated. You want one particular dimension to be transferred (via a cut/paste). 1. Click the Transfer icon from the Step-by-Step Generation dialog box. 2. Select the view in which the current dimension, or the dimension last created, is to be pasted.

125 You want to modify the graphical attributes of the current dimension. You simply need to apply the desired attributes from the toolbar. 9. Click again and continue the process. The dimensions are automatically generated on all the views. The dimensions appear as shown, for example, on the front view documented in this particular case. The Generated Dimensions Analysis dialog box is automatically displayed with the pre-defined settings). This Analysis dialog box shows the corresponding constraints. It is described in detail in Dimension Generation Analysis.

126 Note that you can stop at anytime the generation by clicking or on the contrary accelerate the process by clicking.
