Boring Fixture The intent of the first part of this step-by-step exercises book is to let you practice the various ways of using the workbench for designing jig, foundation or other tooling The other part of the exercises book will enable you to enrich your tooling with using catalog parts and extract documents like BOMs or drawings 3
Step (1): Create a Grid We will first open the Boring_Fixture CATProduct 1 Select the File + Open menu 2 Look in Step1 directory 3 Select Boring_Fixture CATProduct in Step1 4 Click on Open 4
We will now place the grid 5 Select the Grid icon 6 Define the grid as shown in the picture below 7 Click on OK Step (2): Place Members 5
Next we will place members (beams) using the grid as support If you don t succeed in creating the grid in step1, open Boring_Fixture CATProduct stored in \Data_Student\Step2 directory 1 Double-click on Member on Support Icon We need first to select a section in the EN catalog of profiles 2 Select Other Section in Section: field as shown in the picture below 3 Browse to open the EN catalog 6
4 Select the Square tubes family in the EN catalog 5 Select TUBEC250x120 in the sections list 6 Click on OK 7
7 Define the member to place as shown in the picture below 8 Place Beam_1 as shown below 9 Place Beam_2 as shown below 10 Place Beam_3 as shown below 8
We will now carry on member placement with Infill menu 11 Double-click on Infill icon 12 Select a new section TUBEC180x100 in the EN catalog 13 Define infilling members as shown below 14 Select Beam_3 as reference 1 and Beam_2 as reference 2 15 Click on OK 9
16 Modify the definition of the other infill to be created as shown below Next we will use Member menu to carry out member placement 17 Select Member icon 10
18 Define member as shown below 19 Place Beam_6 as shown below using intersection points of the grid 20 Place Beam_7 as shown below using intersection points of the grid 11
21 Place Beam_8 as shown below using intersection points of the grid 12
22 Define a new direction and a length value for the next two beams 23 Place Beam_9 as shown below using intersection point of the grid as start point 24 Place Beam_10 as shown below using intersection point of the grid as start point Both last ones! 13
25 Define member and direction 26 Select the free extremity of the left vertical beam as shown below 27 Select Point Definition icon 14
28 Select Point on Member 29 Select the vertical beam: TUBEC250x120 30 Key-in 1500 in the Offset field or slide the Offset handler 31 Repeat on the right side with a Top Left anchor point 32 Hide the grid 15
Step (3): Create Planar Elements We will now place all the plates, end plates and gussets using the Plate and End Plate menus If you don t succeed in placing members in step2, open Boring_Fixture CATProduct stored in \Data_Student\Step3 directory 1 Select the Plate icon 2 Select the support for the plates as shown in the picture below 3 Key-in 20 for Thickness 4 Select the Sketch icon 5 Select the Rectangle icon 6 Sketch the first plate as shown below 16
7 Select the Exit icon 8 Click on Reverse Direction 9 Click on OK 10 Repeat steps 42 to 50 on the right We are now going to create gussets 11 Select again the Plate icon 12 Select Gusset as type 13 Select the support for the plates as shown in the picture below 14 Select the Sketch icon 15 Select the Right View icon 16 Select the Profile icon 17
17 Sketch the gusset profile as shown in pictures 18 Select the Exit icon 19 Click on Reverse Direction 20 Click on OK 21 Repeat steps 48 to 56 on the right 18
We would like now instantiate both right and left gussets 4 times To do that, as Structural plates are CATPart, we will use the Assembly Design workbench 22 Activate Boring_Fixture 23 Select the Assembly Design workbench icon 24 Select the Define Multi Instantiation icon 25 Select the gusset in the Product tree 26 Key-in 4 as New Instance(s) 27 Key-in 300 as Spacing 28 Click on the Y Direction icon in the Reference Direction frame 29 Click on Reverse in the Reference Direction frame 30 Click on OK 31 Repeat steps 60 to 66 on the right Return to workbench 32 Select the workbench icon 33 Select the Plate icon 19

And to finish with plates, we will place now the two end plates on top of the vertical beams 43 Double-click on the End Plate icon 44 Key-in 250 for Length and Width 45 Key-in 5 for Thickness 46 Select the free extremities of the vertical beams using Ctrl-Click 47 Click on OK 21
Step (4): Create Joints We will now cut all the beams using the Join menu If you don t succeed in creating planar elements in step3, open Boring_Fixture CATProduct stored in \Data_Student\Step4 directory 1 Double-click on Join icon 2 Select Miter cut as Type 3 Select member to trim 4 Select trimming member 5 Click on OK 6 Repeat steps 87 to 90 for each miter cut as indicated in the Exercises book 7 Select Weld cut as Type and do the same operation as for miter cut 8 Save and Close Boring_Fixture Step (5): Modify Your Design 22
