How to join multiple lines into one single object in BricsCAD?
Short Answer
Yes — in BricsCAD, the most common way to join multiple lines into one single object is with the PEDIT command and its Join option. Convert the lines to a polyline when prompted, then join connected segments into one object. Limitation: the lines must touch or fall within a valid join tolerance.
What You Need to Know Before
Warning: If your lines are not exactly connected, even tiny gaps or different Z elevations can prevent them from joining. Also, if one of the objects is on a locked layer, BricsCAD may refuse the edit or leave parts unjoined.
How to Join Multiple Lines into One Single Object in BricsCAD
Command: PEDIT
Shortcut: PE
Quick Steps:
- On the command line, type PE and press Enter, or use Ribbon > Home > Modify panel > Polyline Edit.
- Select one of the lines; when BricsCAD asks whether to turn it into a polyline, choose Yes.
- Type J for Join, select the other connected lines, then set or confirm the fuzz distance/join tolerance if prompted and press Enter.
Variables & Settings
Key Setting: Join tolerance / fuzz distance
Expert Setting: This value controls how far apart endpoints can be and still join into one polyline. Use a small tolerance to avoid bad connections; setting it too high can join geometry you did not intend to merge.
Why it Fails
- Cause 1 (Geometry): Line endpoints do not actually meet, or the objects have different Z values even if they look connected in Top view.
- Cause 2 (layers/Locks): One or more selected objects are on a locked layer, preventing modification.
- Cause 3 (Command/Logic): PEDIT joins lines into a polyline, not into a single plain line object; curved or disconnected segments may remain separate.
Quick Fix & Best Practice
- Quick Fix: Use FLATTEN first if the objects may have different elevations, then run PEDIT > Join again with a small join tolerance.
- Manager’s Verdict: Use PEDIT for drafting and production work whenever you need connected segments to behave as one object. Avoid forcing joins with a large tolerance in precise drawings, especially survey, fabrication, or architectural base files.
FAQ
Can I join lines without converting them to a polyline?
No, the standard professional method uses PEDIT, which converts them into a polyline.
Can BricsCAD join arcs and lines together?
Yes, PEDIT can join connected lines and arcs into one polyline if the geometry is compatible.
Why do my lines look connected but still will not join?
They often have tiny gaps or different Z elevations that must be corrected first.
