Understanding Polyline Creation in Draftsight
Draftsight provides powerful tools for creating and modifying polylines, which are essential for drafting precise designs. This guide outlines the process for utilizing polylines effectively within Draftsight.
Steps to Create a Polyline
Open Draftsight: Launch the Draftsight application and open a new or existing drawing file.
Access the Polyline Tool: Navigate to the Drafting tab on the ribbon. Under the Draw panel, locate and click on the Polyline option.
Define Initial Point: Click in the graphics area to establish the starting point of your polyline.
Set the Endpoint: Move your cursor to designate the endpoint of the first line segment. If transitioning to arcs, type
A
for Arc mode when prompted.Continue Drawing: To add additional segments, continue specifying endpoints as necessary. Each click will create a new line or arc segment.
- Finalize the Polyline: To conclude the polyline creation, either press Enter, which will leave it open, or enter
C
to close it, forming a loop.
Modifying an Existing Polyline
Revising polylines in Draftsight can enhance design flexibility:
Select the Polyline: Click on the polyline you wish to edit from the drawing area.
Utilizing the Editing Tools: Access the Modify tab on the ribbon, and select Edit Polyline. Alternatively, use the command line and type
PEDIT
to activate the polyline edit tool.Options for Modification: You will be presented with various editing options. These can include:
- Joining segments
- Changing widths
- Smoothing curves
- Apply Changes: Follow the command prompts to apply your desired modifications. Confirm each change with Enter as required.
Transforming Objects into Polylines
To convert existing line segments or arcs into a polyline:
Activate the PEDIT Command: Type
PEDIT
into the command line and press Enter.Select Line or Arc: Choose the object(s) you want to convert and press Enter.
Convert to Polyline: When prompted, type
M
for multiple objects. After selection, press Enter again.- Complete Conversion: To finalize, type
J
and press Enter once more.
Creating Arc Segments within Polylines
For drafting curved designs using polylines:
Select Polyline Tool: Follow the initial steps to access the polyline tool.
Specify Segments: As you specify points, switch to Arc mode by typing
A
to create arcs instead of straight lines.- Continue Adding: Repeat this process until you have designed your desired shape, finishing with Enter or closing with
C
.
Common Polyline Questions
What is the main difference between a line and a polyline?
A line is a discrete straight segment with two endpoints, while a polyline can consist of multiple joined segments, including both straight and curved forms. Polylines have properties like total length and area that lines do not possess.
Can I edit a polyline after creation?
Yes, you can modify an existing polyline using the PEDIT command or through the modify features in the Draftsight interface, allowing changes to shape, width, and other attributes.
How do I smooth out a jagged polyline?
To smooth a polyline, use the S (Spline) or F (Fit) options within the PEDIT command to adjust the vertices into smoother curves, reducing sharp corners and facilitating a more fluid design.
