6 Copyright DASSAULT SYSTEMES Creating a Polyline Other Enhancements : Creating a Spline Curve Creating a Connect Curve Intersecting Elements In this lesson you learn how to create some types of Wireframe Elements : Creating Wireframe Elements

7 Copyright DASSAULT SYSTEMES You will learn how to create a polyline. Creating a Polyline V5R8

8 Copyright DASSAULT SYSTEMES Why create Polylines ? You can use this tool to create rapidly a polyline : V5R8 Not using the point-point chain mode tool : Using the line point-point chain mode tool : Creating the lines point-point : n-1 operations Input data : 4 points Creating the polyline: 1 operation Whatever the number of point you want to use, only one operation is necessary to create the polyline.

9 Copyright DASSAULT SYSTEMES Lets see now how to create a Polyline... How to create a Polyline V5R8

10 Copyright DASSAULT SYSTEMES Click OK to create the Polyline. 1 2 Select already existing points Creating a Polyline 3 You can now create a Polyline in one operation. V5R8

11 Copyright DASSAULT SYSTEMES You will learn other enhancements in the Wireframe Creation of the Wireframe and Surface Design workbench Other Enhancement about Wireframe V5R8

12 Copyright DASSAULT SYSTEMES Creating a Spline Curve You can now use a curve to specify a tangency condition at a point of the spline Create the spline selecting existing points. 1 2 Select the point on which you want to add a tangency condition and expand the Parameters panel. 3 In the constraint type field, choose the new option From curve that allows you to choose a curve to add the tangency constraint. Now you can select a curve to specify the tangency constraint : V5R8 4 Note : the point of the spline must lie on the selected curve.

13 Copyright DASSAULT SYSTEMES Select the first curve to connect and a point on this curve. Creating a Connect Curve 4 If needed click on the red arrow located on either point to reverse the orientation of the associated curve, or use the dialog boxs new option. Curve 1 3 Select the second curve to connect and a point on this curve. Point 1 Point 2 Curve 2 Curve orientation Creating a connect curve, you have now the possibility to invert the orientation of the associated curve from the dialog box V5R8

14 Copyright DASSAULT SYSTEMES Select the two curves. Intersecting Elements : Type of created Elements (1/2) 3 Choose the type of element you want to generate. You can choose the type of elements that is created when you perform an intersection operation : V5R8 The type of element that was selected is created (in our exemple, it is a curve that is created).

15 Copyright DASSAULT SYSTEMES Intersecting Elements : Type of created Elements (1/2) Four different type of element can be generated : V5R8 - Points : when intersecting two curves or a curve and a surface. - Curves : when intersecting two curves or a curve and a surface. - Faces : when intersecting a surface with another or a surface with a pad. - Contours : when intersecting a surface with another or a surface with a pad.

16 Copyright DASSAULT SYSTEMES Creating an Offset Surface In this lesson you learn how to create some types of Surface Elements : Creating Surface Elements

17 Copyright DASSAULT SYSTEMES Creating an Offset Surface 2 Select the reference surface and key in the offset value. Click OK to confirm the offset creation. If you want to create both side of the offset surface, choose the Check both side option. 3 4 You can now create both side of an offset surface with the same offset distance. Reference surface V5R8

18 Copyright DASSAULT SYSTEMES Transforming Elements Axis-to-Axis Other Enhancements Splitting and trimming Elements Healing Surfaces Joining Surfaces In this lesson you learn how to perform some Operations : Performing Operations

19 Copyright DASSAULT SYSTEMES You will learn how to perform an Axis-to-Axis transformation. Applying an Axis-to-Axis transformation V5R8

20 Copyright DASSAULT SYSTEMES What is an Axis-to-Axis transformation ? An Axis-to-Axis transformation transform geometry positioned according to an axis system into another axis system : V5R8 Reference Axis System Target Axis System Element to transform Transformed Element The green surface has been duplicated and positioned according to the new axis system.

21 Copyright DASSAULT SYSTEMES Lets see now how to apply an Axis-to-Axis transformation... How to apply an Axis-to-Axis transformation V5R8

22 Copyright DASSAULT SYSTEMES Click OK to create the transformed surface. 1 2 Select the element to transform. Applying an Axis-to-Axis transformation 3 Select the reference Axis System. 4 Select the target Axis System. 5 V5R8

23 Copyright DASSAULT SYSTEMES You will learn other enhancements in the Operations of the Wireframe and Surface Design workbench Other Enhancement about Operations V5R8

24 Copyright DASSAULT SYSTEMES Splitting and Trimming : Intersection Computation While splitting or trimming elements, you can now compute their intersection. Select the elements you want to trim or to split : 1 2 You can now compute the intersection while performing the split or trim operation. 3 V5R8 The elements intersection is computed and the intersection is added in the tree.

25 Copyright DASSAULT SYSTEMES Healing two surfaces, you have now the possibility to allow a remaining gap between the surfaces. Healing Surfaces : distance objective Select the surfaces to heal : 1 2 If you should decide to allow a remaining gap between the surfaces, key in the maximum tolerated value of this gap. Then CATIA inform you about the value of the remaining gap : mm gap Key in a merging distance superior to the gap value. V5R8

26 Copyright DASSAULT SYSTEMES Joining Surfaces : Angle Tolerance While joining surfaces, you can specify an angle tolerance. If the angle value on the edge between two elements is greater than the Angle Tolerance value, the elements are not joined Select the elements to be joined. The tangency discontinuity between these surfaces is 6deg : 1 2 V5R8 3 Click OK to confirm the join creation. 4 Activate the new option Angle Tolerance. CATIA refuses to create the join surface because the tangency discontinuity between the surfaces is greater than the specified angle tolerance:
