Add different blocks based on the angle of the polyline or lwpolilinha.

Add different blocks based on the angle of the polyline or lwpolilinha.

Hello people,
I have some cases and I do not know if it is possible to altoma them with a .lsp, these are my cases:

1. st Block * B * must be inserted in all verticies of my Polylines or LWpoliline.

2. If the angle is straight or up to a maximum of 174 beyond block B, block D will also be added.

3. At the beginning and end of my Polylines or LWpoliline Block A will be added. also at angles greater than 174
However 2 blocks should be added.

I'm going to attach a .dwg file to help with the result, as expected.
Thank you in advance for your help.

Correct file.

I sort of understand 2. but could do with a slightly better explanation of the highlighted red items.

@dlanorh  Thanks for your replay.

In my current file file I show with an example a simpler way of understanding.

 

2. Block B must be inserted when the angles are straight or with a minimum difference (up to 174 °).

 

3. At the beginning and at the end, block A will be added. When there is a greater angle
(174 °), 2 blocks will be added as in the example.

Is this a Hawaiian polyline?

@ronjonp I have a bad English, and this is how it is written in my country kkk

No worries .. I'm sure your Portuguese is better than mine.

I think the penny dropped about half an hour after I replied. Lisp is partly written (1 & first part of 2) ,  tested and working.

Sorry.  re "The penny dropped.." is a local english way of saying that i realised what you meant at a later time.

1. Is finished and working

2 & 3 are half finished as i am still working on the condition statement for the angles

Can you look at the attached dwg and answer the mleadered questions (?)

question.dwg

[JuniorNogueira]

@dlanorh  Exactly!! see .dwg with the expected result.

questionRP.dwg

[dlanorh]

OK. Attached is documented Lisp. This works as I expect it to, but you have the final say. Still not sure I am getting the correct block at intermediate vertices.

 

Any problems let me know.

Very very much Thank you @dlanorh
For an hour this will serve me well !!! you are the best!!!

@JuniorNogueira  You're welcome.

 

Please check that it works correctly for all cases.

 

It can be easily adapted to use a selection set if required.

Yes @dlanorh It works very very well !!! It was fantastic !! 

A selection set would be great !!

 

is it possible to apply a different condition if you see a parallel polyline?

I'll sort the selection set.

 

Re the parallel polyline, send me a drawing showing the condition and i'll let you know.

 

[dlanorh]

Attached is revised lisp to allow polyline selections via selection set.

Hello, how to replace block A to rotate in this position.
I have attached the .dwg example
