Get a point of a polilyne

[Anonymous]

Hi masters!

I am working in a new LISP, to change the dimensions of a drawing for an aligned dimension. Dimensions you can see in the drawing are made of simple lines.

So, first of all i tried to identify the point nº3 of the triangles. After that i will make a dimensions between those 2.

I am stuck in this point and dont know how to get it. I imagine i need to identify the coordinates of those point. If anyone knows any other way to make it easier i will apreciate it.

How i will run the lisp? I will select only the items i need to change, and will run the lisp. I will do the same action again and again until all the dimensions are changed.

There is no need to create the dimstyle and layer, because both will be already created in the drawing.

Thanks in advance!

Hi @Moshe-A , please clear me how the 

(vlax-curve-getEndParam ename)

 can receive a  ename. 

As far I can see at the ACAD help 

(vlax-curve-getEndParam curve-obj)
curve-obj
Type: VLA-object

The object to be measured.

It state that it shall be a VLA-obj

Thanks in advance

@devitg  hi,

Yes years ago i was also amazed to see that on this forum. i think it was Kent Cooper who brought it. apparently it looks like it's undocumented even on new releases 😀

let's hope they will not take it out some day 🙏

I learn a new one today .

Thanks @Kent1Cooper for your update. I will inplement in my lisp.

Thanks @Moshe-A for your lisp. Its a bit complex for me as i see some functions i didnt know. Will check it with calm and see if i can update for other projects i have in mind.

@Anonymous ,

No doubt you can use it in this 'project'. here are the issues that you still have to take care:

1. set reasonable dimension style.

2. set layer for the dimension.

3. set the appropriate DL_OSET_DIST 

these are simple tasks to do and i will be here to help 😀

@Moshe-A  hi , maybe I'm wrong , but it seem to be:  a parenthesis is lost at  

( t
      (command "._dimaligned" "_None" p0 "_None" p1 "_None"     pos_dimlin p0 p1))
     )

after the last NONE , before pos_dimlin

yes thank you. you caught me 😀  my mistake...that's the result of last second change, i added "none" there
