1. Workshop 3.1 Sketching
DesignModeler

2. Goals
Using a simple example, let’s see how we put to use what we’ve seen so far (note RMB = Right Mouse Button).
Goal:
Sketch a rectangle 50mm high and 75mm wide with the bottom left corner at the origin.
Add a 10mm radius circle within the rectangle with the center 20mm from the left side and 30mm from the bottom.
Place all dimensions where they can be easily viewed.
R = 10mm
50mm
75mm
30mm
20mm

3. Launch DesignModeler
Start Workbench. Double click on Geometry under component systems.
This will create a ‘Geometry component’ in the Project Schematic area.

4. Launch DesignModeler…
Right click on and click on “New Geometry…”
This will launch a DM Window with a prompt to select desired length unit. Select “Millimeter” and click OK.

5. Create Geometry
Icon
RMB
When DM starts, switch to sketch mode using the Sketching tab.
Note: use the “Look At” icon (or RMB options) to orient the sketch plane in the normal direction.
Select the “Rectangle” tool and place the cursor at the origin.
Once the “P” (point constraint) symbol shows, click, hold and drag, then release to create the rectangle.
Click
Release
Drag
Hold

6. Create Geometry…
Icon
RMB
Before continuing, click the “Zoom to Fit” icon (or RMB menu).
Now choose the “Circle” tool and click at an approximate location within the rectangle where the center would be, drag and release to create the circle.
Release
Drag
Click, Hold

7. Create Geometry… We’ll now formalize the sketch by adding dimensions.
Width of Rectangle: Select the Dimension toolbox and leave the default selection at “General”.
Click on the top line of the rectangle to display the horizontal dimension ‘H1’.
Move the mouse upwards to move the dimension above the rectangle.
Click again to place the dimension.
Click
Move

8. Create Geometry… Height of Rectangle: With the “General” selection
Click on the right line of the rectangle to display the height dimension.
Move the mouse to select a location for the dimension.
Click to place the dimension.
Diameter of Circle: With the “General” selection
Click on the circle to display the diameter dimension.
Horizontal Distance of Center of Circle: With the “General” selection
Click on the center of circle then click on left vertical edge of the rectangle.
Move the mouse to select a location for the horizontal distance dimension.
Vertical Distance of Center of Circle: With the “General” selection
Click on the center of circle then click on bottom horizontal edge of the rectangle.
Move the mouse to select a location for the vertical distance dimension.

9. Create Geometry…
Next modify the details for each dimension to the desired values as shown.
50mm
D = 20mm
75mm
30mm
20mm

10. Create Geometry…
Use the “Move” function in the Dimension toolbox to position the dimensions
Select Move in the Dimensions toolbox.
Click on the dimension to be moved.
Move the mouse to select a position for the dimension.
Click to place the dimension.

11. Create Geometry… Now try animating several dimensions:
Choose the “Animate” function then click on a dimension in the graphics window
Change the dimension display from “Name” to “Value”.

12. Create Geometry…
As a last check of our stated goals go to the details for sketch 1 and change “Show Constraints?” to “Yes”.
Scroll down to the details for Line7 and note the base point is coincident with the origin - - DM captured our design intent during sketching.
Note: leave DM session running as we will continue with this geometry later.
