3.CREATING CONNECTORS BETWEEN THE COMPONENTS:
i)SEAM QUAD (ANGLED + CAPPED + L) BETWEEN RIGHT RAIL 2 & FRONT TRUSS 1 :
FIG 5 CONNECTORS TOOL IN THE 2-D TOOL BAR
The Seam connector in connectors tool in the 2-d tool bar is selected
FIG 6 SEAM CONNECTOR IN THE 2-D CONNECTORS
The node path is selected in the Seam quad connector and the Spacing 0f 5 mm which is the distance between the elements of the two components is given. The Connector type is Seam Quad (Angeled + Capped + L) & the connector is created.
Note: Please Refer the Attached Word File CREATING THE SEAM QUAD (ANGLED + CAPPED + L) for FIG 7
Note: Please Refer the Attached Word File CREATION OF THE SEAM QUAD (ANGLED + CAPPED + L) for FIG 8
ii)QUAD ELEMENTS BETWEEN LEFT RAIL 2 & FRONT TRUSS 1:
The Seam connector in connectors tool in the 2-d tool bar is selected
FIG 9 CONNECTORS TOOL IN THE 2-D TOOL BAR
The nodes are selected in the Seam quad connector and the Spacing 0f 5 mm which is the distance between the elements of the two components is given. The Connector type is Quad & the connector is created.

FIG 11 CREATION OF THE QUAD ELEMENTS
iii)SPOT WELD OF 3 LAYERS & 5 MM DIAMETER BETWEEN FORNT TRUSS 2 , FRONT TRUSS 1 & RIGHT RAIL 1:
The Spot Connector option in the 2-d Connectors is selected.
FIG 12 CONNECTORS TOOL IN THE 2-D TOOL BAR
In the Spot connector tool, the nodes for which the Connectors are to be created are selected. The SPACING value is kept at 5mm and the TOLERENCE Value is kept at 10mm. The Connector Type is WELD & Diameter value is kept at 5mm and the number of layers is choosen to be 3. The 3 Components between which the Connectors are to be created are selected and then the Create button is hit.
FIG 13 CREATING THE SPOT WELD WITH 3 LAYERS OF 5MM DIAMETER
The Spot Weld connector with 3 Layers and 5mm diameter are cretedbetween the 3 Components I.e Front Truss 1, Front Truss 2 & Right Rail 1.

iv)HEXA ADHESIVE BETWEEN FRONT TRUSS 2,FRONT TRUSS 1 & LEFT RAIL 1:
The Seam connectors from the connectors tool panel is selected
FIG 15 SEAM TOOL IN THE CONNECTORS PANEL
The Nodes for which the adhesive connector is to be produced is selected along with the component between which the connector is to be created and the thickness of the connector is given after measuring the distance between the nodes of the two different components is measured.
