Assembling Lines to Polygons
Convert a group of lines and arcs to a polygon or create a polygon by setting an enclosed space.
\aspol
You can create a polygon from:
A selection group
Whole file
Enclosed area
Polygon from a group of lines
Search for a closed loop of lines connected to the entity that you indicate can limit the search to a selection group or search all of the lines connected to the indicated line. Specify if you want to limit the search a selection group only or to all the connected entities. The group must be comprised of contiguous line entities in a closed loop. Indicate a line (or arc) in the group of lines and arcs forming the closed loop. The loop is highlighted and you are asked to confirm your selection.
If you want to select a different loop, do not confirm the selection. Alternative groups are then searched, and additional possibilities are highlighted. This allows you to select the correct loop when the indicated line is included in more than one loop. If you confirm the loop, a closed positive polygon is created.
The system then returns to the beginning of the command and prompts you to assemble another group. If you continue to assemble additional groups in this manner, they become part of the first polygon entity. If you enter n, you terminate the command.
Polygon from enclosed area
A new option enables you to assemble a polygon entity from an enclosed space that is an area closed or bordered on all sides by other entities, such as lines, polygons and walls (not help lines).
You can indicate multiple enclosed spaces as well. These will be considered as a single polygon with multiple loops
The new option creates a new polygon superimposed on the area without changing the original entities, unlike the other options that actually convert the component entities.
Polygons can be exploded into lines. See the Exploding a polygon into lines (\expol) command.
HINT If the command does not identify an area that you know to be enclosed, try changing the advanced settings. The tolerances may be too small (or large) for the scale of your model. See Hatching & Patterns, Hatching a polygon (\hatch).
