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:
- 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.
- Place a circle perpendicular to the end of the spline.
- Use SWEEP.
- Select the shape
- Hit Enter
- Then select the line.
Tip: for more unusual results try using the twist mode.
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:
- Create your top and base parts in the same way as the balusters.
- Next use EXT Subtract, Both sides.
- Apply a chamfer to the hard edges.
For this example I used a radius value of 20.
- Then draw in the columns. Use ARRAYPOLAR to repeat the object 4 times.
- Use UNI to create a solid object.
- 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.
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.
Join me next week when I make the bathroom. Learn even more advanced CAD modeling techniques.
