2 Copyright DASSAULT SYSTEMES Exercise Connector Housing: Presentation In this exercise you will learn Generative Drafting fundamental concepts by generating the drawing of the connector housing from the 3D Part. This process includes the creation or generation of all necessary views, dimensions and Annotations. You will also see the associatively of the 3D part to the drawing when the connector housing is modified.

3 Copyright DASSAULT SYSTEMES Design Intent: Connector Housing Define Datum A for the molds splitting or parting element. Generating dimensions for the general shape of the part; referencing the parting face as much as possible. Manual dimensioning of all additional geometry such as catch, detent and clip. Define tolerances in relation to the parts functional constraints. Mold parting face Catch Clip Detent

4 Copyright DASSAULT SYSTEMES Design Process: Connector Housing D Part Design Changes 2 Starting the drawing and creating the views 1 Adding views Editing of the view layout and properties 3 Dimensioning, tolerancing & Annotating and dressing up 4 Checking for changes and Printing 5

5 Copyright DASSAULT SYSTEMES Givens: Connector Housing Start from the 3D solid part called « Connector Housing 1 » Generate the following views: Front View Bottom View Section View passing through the holes Section View passing through the Catch mid plane A Detail View of the Catch A Detail View of the Clip A Detail View of the Detent 2 isometric views showing the outside and the inside of the part Add all necessary dimensions and associative annotations Add all necessary annotations Add a title block with the name of the part, the date, the scale and the standard used plus fields for Names and Comments Detent Catch Clip

6 Copyright DASSAULT SYSTEMES Exercise Connector Housing (1) : Views Generation In this step you will quickly Generate 3 main views and an isometric view of the connector housing. You will then check drawing default options. 05 min

7 Copyright DASSAULT SYSTEMES Do It Yourself While the Connector Housing 1 part is in the Part Design workbench, go to the Drafting workbench Set the ANSI standard and B ANSI sheet format Set the sheet properties to third angle projection standard Generate the Front, Top and Right views plus an isometric view Set the default fillet representation to off for later views Save the drawing with its link to the 3D part Connector Housing 1. Load: CATGDAConnectorHousing1.CATPart

8 Copyright DASSAULT SYSTEMES Catch Detent Clip 20 min Exercise Connector Housing (2) : Additional Views In this step you will add two section views and three detail views. You will also an extra isometric view. Do not dimension any views yet.

9 Copyright DASSAULT SYSTEMES Do it Yourself 1. Delete the right view and replace it with a section view A-A passing through the middle of the two threaded holes and located on the left of the front view 2. From the mid plane of the Catch, generate a section view B-B and position it above the Top view 3. From section A-A, make a detail view around the Detent with default scale of 2 4. From section A-A, make a detail view around the Clip with default scale of 2 5. From section B-B, make a detail view around the Catch with a rectangle callout and with default scale of 2 6. Add an isometric view showing the inside of the connector housing Load: CATGDAConnector_2.CATDrawing

10 Copyright DASSAULT SYSTEMES Exercise Connector Housing (3) : Properties In this step you will change the view properties of the name,scale, fillet representation and hidden line visualization. You will modify a detail view callout and redefine a section view profile. You will also change the position of a view and the hatching representation. Do not dimension any views yet. 15 min

11 Copyright DASSAULT SYSTEMES Delete name and scale on front view and bottom view and change section views name to A-A and B-B 2. Change scale of all detail views to 6 and change scale of isometric views to.5 3. Modify section B-B so that it passes through the catch and one of the through holes 4. Change the detail E callout such that the E is located between the breaks of the circle 5. Remove all unnecessary hidden lines in the Front View 6. Put a plastic hatching on all sections 7. Rearrange all views on the sheet as shown above Load: CATGDAConnector_3. CATDrawing Do it Yourself

12 Copyright DASSAULT SYSTEMES min Exercise Connector Housing (4) : Dimensioning & Tolerancing In this step you will dimension two parts with the automatic and manual methods. You will also add a datum and a Geometric tolerance

13 Copyright DASSAULT SYSTEMES Generate the 3D constraints in step by step, reposition, transfer and discard appropriate dimensions 2. Manually dimension the front and top views as shown above 3. Add datum A on section A-A and Geometric tolerances on Detail C as shown above Front view Top view Detail CSection A-A datum Load: CATGDAConnector_4. CATDrawing Do it Yourself

14 Copyright DASSAULT SYSTEMES Exercise Connector Housing (5) : Finalizing the Drawing In this step change the specifications in 3D and make the drawing up to date with the 3D parts new dimensions. Draw a title block and store it, and Print the drawing on a simple office printer 30 min

15 Copyright DASSAULT SYSTEMES Do it Yourself (1/2) 1. Open the source document and change to the Part Design Workbench. Change the length of the connector housing to 60mm, the distance between the hole and the edge to 12mm, the distance between the 2 holes to 30mm and the diameter of the holes to 2mm. 2. While the drawing is open, save the Part under the name Connector Housing Update the drawing and check that the dimensions are correct on the Front View Load: CATGDAConnector_5.CATPart

16 Copyright DASSAULT SYSTEMES Do it Yourself (2/2) 4. Using a macro create a Title Block in the background. 5. Add the above title block and general specification text 6. Remove all frames around views and print it on a A4 paper format
