Serpentine Block Walls

Serpentine block walls

Here's 1 I'm up against:

This could be brick, CMU or glass tile like shown:

The MEASURE command really sucks when it comes aligning a block along a serpentine path

Rules ( in this case )
  • The glass tile is 6 Wide x 6 High x 4 Thick -  GLSB-664
  • Horizontal grout joint : consistent 0.4 thick
  • Vertical grout joints :     Inside Radius of the curve : Minimum Width 0.2  Outside Radius of the curve : No Maximum Width

The BLOCK GLSB-664 has the horizontal grout joints built into it ( 6.40 high )
It has no vertical joints at all.  It would be arrayed @ 6.4 along a straight path

So how to calculate the INSERT points and angles from a curved path.  In the real world, the first and last blocks will probably be a short straight segment, then start the curve.

I will probably extrapolate the vertical joint points from the INSERT data. 

Any ideas?  Thanks  -David

Use the vlax-curve-* functions to calculate the necessary points and tangent directions (derivatives) along the curve.

I think I will have to offset the center line path 2" on either side and then find the paths of the inner radius with a curve function.  Transitioning from 1 direction to the other will be a challenge to say the least.

OK, So I cheated

  • Divide the path based of the nominal x value of the tile / opening.
  • Make the list of POINT entity values
  • Add the start and end point of the path to the point list
  • TRACE using the point list ( TRACEWID = the F-B Dim   THICKNESS = Tile Height + Grout Joint Width )
  • Convert the TRACE entities to blocks and grout or frames and openings

The wood could be real world correct, bricks and glass tiles, probably not.  But it looks good.

It certainly does!  8-)
