Creating custom vents

Here are two ways to make a standard vent slot with rounded ends. If you use the Grid, you can place (and evenly space) many of them quickly.

To make a vent slot using the grid

1. Turn on the grid.
2. Draw a rectangle and make it the size you want it to be. It will snap to the grid lines.
3. Draw a circle at each end of the rectangle, and let them snap to the top and bottom of the rectangle.
4. Merge the three objects.

To make a vent slot without using the grid

1. Draw a rectangle and specify its Width and Height in the Properties panel.
2. Draw a circle at each end of the rectangle, and make their Diameters the same as the Height of the rectangle.
3. Click the Measure tool, select the center of the rectangle and the center of one circle, change the distance to "0.0", then repeat this step for the second circle.
4. Merge the three objects.

Note: You can make a vent cutout of any shape using the Path tool.
