Can I draw a construction line that extends to infinity in BricsCAD?
Short Answer
Yes — in BricsCAD you can draw a construction line that extends to infinity by using the xline command, which is the standard professional method for creating infinite reference geometry. It is fast, precise, and ideal for layout, alignment, and projection work. Limitation: XLINE objects are non-plotting only if you manage their layer correctly.
What You Need to Know Before
Warning: Infinite construction lines can visually clutter a drawing very quickly, especially in dense model space files. If you place XLINEs on a normal plotting layer or forget to isolate them, they can confuse selection, snapping, and downstream editing.
How to Draw an Infinite Construction Line in BricsCAD
Command: XLINE
Shortcut: XL
Quick Steps:
- Start XLINE by typing
XLor go to the Ribbon and open the Draw panel if your workspace shows it. - Choose the most common option, usually Hor, Ver, or click two points for an angled construction line.
- Place the line in the required direction, then press Enter to finish or continue placing more XLINEs.
- Start XLINE by typing
Variables & Settings
Key Setting: Layer Plot toggle
Expert Setting: Put construction lines on a dedicated non-plot layer, then turn off the layer’s Plot option in layer properties. This keeps XLINE geometry available for drafting and snapping without printing it.
Why it Fails
Cause 1 (Geometry): The XLINE was created at the wrong angle or through the wrong base point, so it appears unusable even though the command worked correctly.
Cause 2 (layers/Locks): The current layer is locked, frozen, or set to an unsuitable color/linetype, making the construction line hard to see or impossible to create.
Cause 3 (Command/Logic): Users sometimes use LINE instead of XLINE, which creates a finite segment rather than a true infinite construction line.
Quick Fix & Best Practice
Quick Fix: Run XLINE, use the Hor or Ver option, and place the result on a dedicated non-plot construction layer.
Manager’s Verdict: Use XLINE for temporary alignment, projection, and setup geometry, but avoid leaving excessive infinite lines in production deliverables. For final documentation, clean them up or isolate them on controlled layers.
FAQ
Can I trim an XLINE in BricsCAD?
No, an XLINE remains infinite; use LINE or ray if you need limited length behavior.
What is the difference between XLINE and RAY?
XLINE extends infinitely in both directions, while RAY extends infinitely in one direction only.
Can XLINE objects be snapped to like normal geometry?
Yes, you can use object snaps on XLINEs for alignment and construction work.
