2D, 3D, BIM - 4: More Advanced Modeling

The Handrail

I used EXPLODE (as covered last week) on the array then edited the balusters on the middle step. Afterward, I created a spline along the top of the balusters and swept along the line.

To do this:

    1. Draw a 3D Polyline or Spline along the top points of the balusters.

      You can not fillet 3D polylines, so I used circles. Then trimmed and joined the lines together.
    
    1. Place a circle perpendicular to the end of the spline.2D, 3D, BIM - 4 More Advanced Modeling- sweep-1-1024x483
    2. Use SWEEP.
    3. Select the shape
    4. Hit Enter
    5. Then select the line.
      Tip: for more unusual results try using the twist mode.2D, 3D, BIM - 4 More Advanced Modeling- rail

The Newel

To make the newel I used a similar technique to model the balusters. I then extruded rectangles to remove the excess material, chamfered, added columns and applied a twist.

Note: Twist is only available in BricsCAD Mechanical or BricsCAD BIM.

To do this:

  1. Create your top and base parts in the same way as the balusters.
  2. Next use EXT Subtract, Both sides.
  3. Apply a chamfer to the hard edges.
    For this example I used a radius value of 20.
  4. Then draw in the columns. Use ARRAYPOLAR to repeat the object 4 times.
  5. Use UNI to create a solid object.
  6. Finally, apply TWIST. Use the centerline as your axis. Place the start and end points of twisting axis between the rectangular portions to prevent the rectangular portions becoming twisted.2D, 3D, BIM - 4 More Advanced Modeling- twistpoints-1024x530

Finishing Up

I removed the excess material by drawing the cutting line on to the steps and added wall details. Then I imported the newel and extended the handrail.

Dealing with the Concrete 'Crisis': Leveraging Point Cloud in CAD for Surface Deviation Analysis

In the wake of a concrete 'crisis' affecting existing buildings, such as many schools in the UK constructed with Reinforced Autoclaved Aerated Concrete (RAAC), the need for precise assessment and remediation strategies has never been more critical. Integrated into CAD software, point cloud technology becomes valuable for addressing surface deviation concerns in RAAC structures.
