Is there a specific tool for drawing construction lines in BricsCAD?

Short Answer

Yes — in BricsCAD, the most common professional way to draw construction lines is with the xline command. It creates infinite reference lines used for layout, alignment, and projection work without needing fixed endpoints. A key limitation is that XLINE objects can clutter drawings quickly if they are not placed on a dedicated layer.

What You Need to Know Before

Warning: XLINE creates infinite geometry, so construction lines may extend far beyond your visible workspace and interfere with selection, snapping, plotting control, or cleanup. If they are placed on a normal working layer, users often mistake them for production geometry.

How to Draw Construction Lines

• Command: XLINE

• Shortcut: XL

• Quick Steps:

  1. On the Ribbon, go to Home > Draw and start XLINE, or type XL and press Enter.
  2. Choose a common option such as Hor, Ver, or Ang from the command line, depending on the construction direction you need.
  3. Pick the reference point to place the construction line, then continue placing more lines or press Enter to finish.

Variables & Settings

• Key Setting: Use the Layer control to place construction lines on a dedicated non-plot layer

• Expert Setting: Creating a layer such as CONST and turning off Plot for that layer keeps XLINE geometry available for drafting and snapping while preventing accidental output on printed drawings.

Why it Fails

• Cause 1 (Geometry): Users expect XLINE to behave like a finite line, but it is infinite and may overlap the entire drawing area.
• Cause 2 (layers/Locks): If the current layer is locked or frozen, the construction line may not be created where expected or may appear unavailable for editing.
• Cause 3 (Command/Logic): Choosing the wrong XLINE option, such as Horizontal instead of Angle, creates valid but unusable reference geometry for the intended layout.

Quick Fix & Best Practice

• Quick Fix: Run XLINE, use the correct option like Hor or Ver, and place the result on a dedicated non-plot construction layer.
• Manager’s Verdict: Use XLINE for fast layout references, alignments, and projections, but avoid leaving construction lines mixed with final geometry in issued production drawings.

FAQ

Can I trim a construction line in BricsCAD?

Yes, but the standard XLINE object is meant to stay infinite, so professionals usually keep it as a reference instead of trimming it.

Is there a shortcut for construction lines in BricsCAD?

Yes, the common shortcut is XL.

Should construction lines be placed on a separate layer?

Yes, that is best practice so they can be isolated, turned off, or excluded from plotting easily.
