Is it possible to view a drawing in 3D perspective in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — in BricsCAD, you can view a drawing in 3d perspective by switching the viewport to a perspective visual style using the DVIEW command, which is the most common professional method for perspective viewing. This works best in model space. Limitation: it changes the view only, not 2D geometry into true 3D objects.

What You Need to Know Before

Warning: perspective view in BricsCAD can make flat 2d drawings look distorted, which often misleads users into thinking the geometry has changed. If your UCS, view direction, or visual style is wrong, the result may appear blank or unusable.

How to View a Drawing in 3D Perspective in BricsCAD

  • Command: DVIEW

  • Shortcut: No default shortcut

  • Quick Steps:

    1. In Model space, open the drawing and switch to a 3D-friendly view from the View controls if needed.
    2. Type DVIEW and select the objects, or press Enter to use the whole drawing.
    3. Choose the POints or TWist options if needed, then use the Distance option and enable Perspective to turn the view on.

Variables & Settings

  • Key Setting: Perspective toggle in the viewport/view settings

  • Expert Setting: If Perspective is off, the model stays in parallel projection even when you orbit in a 3D view. Turning Perspective on adds depth visually, but it can reduce precision for drafting tasks and make alignment harder on 2D-only files.

Why it Fails

  • Cause 1 (Geometry): The drawing contains only 2D linework on a flat plane, so perspective changes the camera view but does not create real depth.
  • Cause 2 (layers/Locks): Important objects may be on frozen, off, or locked layers, so the perspective view seems empty or incomplete.
  • Cause 3 (Command/Logic): The user applies perspective in paper space or from an unsuitable top view, where the effect is minimal or visually confusing.

Quick Fix & Best Practice

  • Quick Fix: Use DVIEW, then switch to a SW Isometric view before enabling Perspective so the depth effect is clearly visible.
  • Manager’s Verdict: Use perspective only for review, presentation, or visual checking. Avoid it for precise drafting, dimensioning, or production sheet setup because parallel views are more reliable.

FAQ

Can I use 3D Orbit instead of DVIEW?
Yes, but DVIEW is the more standard method for explicitly enabling perspective.

Does perspective view turn 2D drawings into 3D models?
No, it only changes how the drawing is displayed.

Can I print a perspective view in BricsCAD?
Yes, if the viewport is set correctly, but it is usually better for presentation than documentation.
