Automatic lines from left points to right ones

Automatic lines from left points to right ones

Hi,

 

Does anyone know how to create automatic lines from left points to right ones as shown in the snapshots attached?

 

I have divided two arcs (right and left) into 160 segments. So, what I have got is these points which I would like link each other through lines/segments automatically instead of making them one by one.

 

Any thoughts would be appreciate .

 

Regards

Leandro

Hi,

 

i suggest to use ARRAY  command with known angle spaces that will achieve your need.

i forget to say that with Array ( Polar ) you can get it by specifying and filling :

  • Items : specify the number of items . 
  • Between : specify the angle between items . 
  • Fill : specify the angle between the first and the last item in the array .

If those Points are from DIVIDE-ing two concentric Arcs in the configuration that would result from Offsetting one to get the other [whether you actually made them that way or not], then there's a way to do this without the Points at all.  You can put those Lines in place directly from the original Arcs, without  DIVIDE-ing them first.

 

Go and get DivideMeasurePlus.lsp, >>here<<.  Load that.

 

Draw a vertical Line of the distance between the Arcs, anywhere.  You can draw it between Arc ends, and ROTATE it to be vertical.  [It needs to be vertical, for the options described below, so that the alignment direction tangent to an Arc at a given location along the Arc will place each copy of the Line perpendicular to the Arc.]

 

Call up the DIV+ command.  Choose the User-Selection option [one of the major enhancements compared to ordinary DIVIDE], and select that Line.  When it asks for a "Base point in relation to selection: ", pick the bottom end of the Line.

 

Accept the offered default Aligned option for the rotation.  Give it your number of segments [160 in your example].  Accept the offered Standard default for placement in relation to the segment-division locations, and the offered 0 default for inset from the ends [another option regular DIVIDE doesn't offer], and the offered Yes default for placement at the ends [yet another thing regular DIVIDE won't do].

 

When it asks you to "Select object to divide: ", pick the outer Arc, anywhere.

 

You can get the same result from it in some other ways:  you can pick the top  end of the Line as the base, and pick the inner  Arc to divide;  or you can draw the Line horizontally, and use the Relative-angle to the path rotation option [another choice not available in ordinary DIVIDE], and give it 90 degrees and pick the outer Arc, or 270 degrees and pick the inner one.
