DesignModeler-Line and Surface Bodies

Goals:

– Create a sketch representing beams used to stiffen a panel.

– Create a line body from the sketch.

– Choose a beam cross section to be used and assign it to the line body.

– Create a surface model representing the panel.

DM will Open. When prompted choose “mm” as the length unit

Create a rectangle in the XY Plane [Sketch] > Rectangle

1. Place the cursor near the origin until ‘P’ appears, click then drag to define the rectangle

Click “>Look At” & “>Zoom to Fit” tool buttons, and Triad ISO Ball as desired.

Dimension the rectangle 600X300 mm as shown [Sketch] > Dimension > General

Horizontal = 600 mm

Vertical = 300 mm

Fit the sketch and move dimensions as necessary [Sketch] > Dimension > Move

Add 2 vertical lines and dimension as shown

[Sketch] > Draw > Line

1. Place the cursor near the top line until the ‘C’ coincidence constraint appears. Move the cursor to the bottom line until the ‘C’ appears and a ‘V’ indicating a vertical constraint.
2. Repeat for second line

Apply horizontal dimensions as shown.

[Sketch] > Dimension > Horizontal

Adjust Details so all dimensions are as indicated

Create a Line Body from Sketch1

[Main Menu] > Concept > Lines From Sketches

1. Select “Sketch1” from the Tree (click the “+” near the XYPlane to expand that branch if necessary) and “>Details>Apply” it as the base object
2. Click >Generate

Select a rectangular tube type cross section: [Main Menu] > Concept > Cross Section > Rectangular Tube

After selection, the cross section is displayed with its dimensions.

In this case we will use the default dimensions.

If desired the cross section Details can be changed to modify the cross section.

 

With a cross section selected we now need to associate it with our line body.

1. Highlight the line body in the tree and the details shows that no cross section is yet associated with it.

[tree] > 1 Part, 1 Body > Line Body (at bottom of tree)

1. Click in the “Cross Section” field

1. Choose “RecTube1” from the drop down list

 

1. After assigning the cross section to the line body the default display shows the line body with its cross section alignment (see right). We can also display the beam with the cross section displayed as a solid.

[Main Menu] > View > Show Cross Sections Solids
