How to fill a shape with a solid color or a pattern in BricsCAD?
Short Answer
Yes — in BricsCAD, the standard professional way to fill a closed shape with a solid color or pattern is to use the HATCH command. Pick a closed boundary, then choose a hatch pattern or Solid in the Hatch options. Limitation: open or broken boundaries usually prevent the hatch from generating correctly.
What You Need to Know Before
Warning: Hatching often fails when the boundary has tiny gaps, overlapping segments, or non-coplanar geometry, even if the shape looks closed on screen. Very dense patterns can also slow redraw and plotting in large drawings.
How to Fill a Shape with a Solid Color or a Pattern in BricsCAD
Command: HATCH
Shortcut: H
Quick Steps:
- On the Ribbon, go to Draw or type H and press Enter to start HATCH.
- In the Hatch panel, set Pattern to a hatch type or choose Solid, then adjust a real option such as Scale or Angle.
- Click Pick Points, click inside the closed area, then press Enter to create the fill.
Variables & Settings
Key Setting: Associative
Expert Setting: Turn Associative on if you want the hatch to update when the boundary changes. Turn it off if you need a static hatch that will not react to later edits.
Why it Fails
- Cause 1 (Geometry): The boundary is not fully closed, or it contains tiny gaps, duplicated segments, or objects at different elevations.
- Cause 2 (layers/Locks): The target layer or boundary layer is locked, frozen, or not plottable, which can block editing or make the hatch appear missing.
- Cause 3 (Command/Logic): The hatch scale is too large or too small for the shape, so the pattern looks blank, solid, or unreadable.
Quick Fix & Best Practice
- Quick Fix: Use PEDIT or BOUNDARY to create a clean closed boundary first, then run HATCH again with Associative enabled.
- Manager’s Verdict: Use Solid fills for clarity and plotting speed, and use patterned hatches only when they communicate real material or drafting meaning.
FAQ
Can I hatch with a gradient in BricsCAD?
Yes, if your BricsCAD version supports gradient fills in the Hatch options.
Can I edit a hatch after placing it?
Yes, select the hatch and change properties such as pattern, scale, angle, or associativity.
Why does my hatch not show after I create it?
The boundary may be invalid, or the hatch scale may be incorrect for the size of the area.
