Can I convert a simple line into a polyline in BricsCAD?
Short Answer
Yes — in BricsCAD, you can convert a simple line into a polyline using the PEDIT command, which is the most common professional method. Select the line, confirm conversion to a polyline, then continue editing as needed. This works well for individual lines, but disconnected geometry may need extra joining first.
What You Need to Know Before
Warning: If the line is part of a broken or slightly misaligned chain, conversion alone will not create one continuous polyline. A very small gap, different elevation, or locked object can cause the join process to fail even when the segments look connected on screen.
How to Convert a Line into a Polyline in BricsCAD
Command: PEDIT
Shortcut: PE
Quick Steps:
- Type PEDIT in the command line, or go to Modify panel if shown in your workspace.
- Select the line you want to convert, then choose Yes when prompted to turn it into a polyline.
- Press Enter to finish, or use the Join option if you want to combine connected lines and arcs into one polyline.
Variables & Settings
Key Setting: Join option inside PEDIT
Expert Setting: When using Join, pay attention to the join tolerance behavior. If endpoints are not exactly touching, the objects may not join into one polyline unless the gap is within acceptable tolerance or the geometry is cleaned up first.
Why it Fails
Cause 1 (Geometry): The selected objects are not truly connected, or they have different elevations/Z values, so BricsCAD cannot form one continuous polyline.
Cause 2 (layers/Locks): The line is on a locked layer, or one of the objects you want to join is locked, preventing modification.
Cause 3 (Command/Logic): PEDIT converts a single line to a polyline, but it does not automatically fix broken topology or force unrelated objects into valid polyline geometry.
Quick Fix & Best Practice
Quick Fix: Run PEDIT, select the line, confirm conversion, then use Join after correcting small gaps or flattening inconsistent geometry if needed.
Manager’s Verdict: Use PEDIT for routine line-to-polyline conversion because it is fast, standard, and reliable. Avoid using it as a repair tool for messy imported geometry until gaps, overlaps, and Z-value issues are cleaned up.
FAQ
Can PEDIT convert multiple lines into one polyline?
Yes, if the lines are connected and join successfully.
Can I convert a line and arc into one polyline?
Yes, PEDIT can join lines and arcs into a single polyline when their endpoints match.
Why does BricsCAD ask if I want to turn it into one?
Because a basic line is a different object type and must be converted before polyline editing options can be used.
