Circles Constructed Based on 2D Projection, 2D Fragment or Copy

Such circles can be created in the object snapping mode, if the respective flag is set in the command “SO:
Set System Options” on the “Snap” tab. Move the cursor over a graphic entity – a circle or an arc on a
2D projection, 2D fragment or a copy. The entity will be pre-highlighted. Clicking at that moment creates
a circle based on the selected entity.
If the object-snapping mode is off, then circles can be created based on 2D projection entities only. To do so,
use the option and select the desired projection on the drawing. The selected projection will be
highlighted, and the cursor will gain the glyph . Now, to create a circle, simply point the cursor at a
projection entity – arc or circle - and click .
The following options will then become available in the automenu:
Circle Parameters
Set Circle parameters
Cancel selection
Various parameters need to be defined when creating or editing circles. The geometrical parameters – the
radius or the offset for concentric circles can be defined in the transparent mode via the property window.
However, the general system parameters can only be accessed via the option that provides access to all
circle parameters via a dialog box.
Radius. Defines the circle radius. Allows numerical value, variable or
expression input.
Level. Places the circle being created on a certain visibility level, used
for hiding certain elements from display when necessary.
Layer. Is used for linking the circle being created to a certain layer.
Color. This parameter defines the color of displaying the circle on the
screen.
Set as default. When this flag is set, the parameters defined in this
dialog box will be used in creation of new construction entities
(except the “Radius” parameter).
