Drawing spirals in Corel
You can draw two types of spirals: symmetrical and logarithmic. Symmetrical spirals expand evenly so that the distance between each revolution is equal. Logarithmic spirals expand with increasingly larger distances between revolutions. You can set the rate by which a logarithmic spiral expands outward
AutoCAD OFFSETGAPTYPE System Variable
Type: Integer
Saved in: Registry
Initial value: 0
Controls how potential gaps between segments are treated when polylines are offset.
0 Fills the gaps by extending the polyline segments
1 Fills the gaps with filleted arc segments (the radius of each arc segment is equal to the offset distance)
2 Fills the gaps with chamfered line segments (the perpendicular distance to each chamfer is equal to the offset distance)

You can quickly create a closed object from line segments by selecting which lines you want to connect and the shape of the connecting line.
You can connect lines using the closest nodes between lines. The connecting line can be either straight or curved. You can also connect lines using the start to end nodes of the lines. The end node of the first selected line connects directly with the starting node of the closest selected line. The connected lines will take on the properties of the first line selected.
Closing multiple line segments can be the starting point for more complex drawings.
To close multiple line segments
Hold down Shift, and select each object using the Pick tool .

Corel Tutorial : Drawing spirals
You can draw two types of spirals: symmetrical and logarithmic. Symmetrical spirals expand evenly so that the distance between each revolution is equal. Logarithmic spirals expand with increasingly larger distances between revolutions. You can set the rate by which a logarithmic spiral expands outward.
To draw a spiral
- Open the Object flyout , and click the Spiral tool .
- Type a value in the Spiral revolutions box on the property bar.
- On the property bar, click one of the following buttons:
Symmetrical spiral
Logarithmic spiral
If you want to change the amount by which the spiral expands as it moves outward, move the Spiral expansion slider.
Drag diagonally in the drawing window until the spiral is the required size.
You can draw a spiral from its center outward by holding down Shift as you drag.
You can also draw a spiral with even horizontal and vertical dimensions by holding down Ctrl as you drag.
