Does anyone have or know of a LISP application that
will making the selection of a group of level lines, it is possible to click freely among them, and the application calculates (and writes in the drawing) the height by interpolation of the two pairs of points closer to the adjacent level curves.
- select Pair of points (two texts) and calculate the beween elevetions (photo1)
- select level lines (polilynes with angle of inclination) and calculate the beween elevetions (photo2)
You're looking for a lisp routine that will calculate and input a spot elevation based upon a random point you select that falls between two contours. Does that accurately describe it?
I need a lisp to do two things
1) if i have two points with elevetion text click the first elevetion text then the second elevetion text and when i click between them like the (photo 1) to caclulate the elevetion and write the text
2) if i have contours (polylines ith elevetion) to select them all and when i pick to any point writes me the correct elevetion
I believe the same logic applies to both, for number 1) are the points elevated to correspond with the text value? are these attribute values? [bTW, i dont see any point entity on the snapshot], for number 2), yes, but whats confusing is the "select them all" part, or do you mean two at a time regardless if its adjacent to each other or not?
The first two statements pointing to the TEXT string as the source now you're saying its the Endpoints of the line?
To write an effective code you need the distance between two points. so can we assume if it is indeed the text entity the "point" will be the insertion point?
How about posting a sample drawing file to clear the confusion.
