So, if from variable pts you get something like "<Selection set: 3121e>", that means the TEXT is inside the polygon, otherwise, you will get nil. Instead of (0 . "POINT") you need to use (0 . "TEXT"). This part I don't understand.

Also, you didn't mentioned what is that point in the polygon, what it present. Can you describe it more or give an example file?

Hi @maahee, You can first select that object using (setq obj (car (entsel "\nSelect the object:"))) ;an example Then you can read a X, Y values from closed polygon (if it's from polyline) using (setq ptlist (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget obj)))) And at final, you can use (setq pts (ssget "_WP" ptlist '((0 . "POINT"))) I hope you will find a right way to do that.

I will not answer your question for now, because I am interested in knowing the possible solutions proposed by others.

That's a good question. It's not as easy as it might seem at first glance. Although having a closed polyline makes the job easier. Just one thing should be clear: calculating the polygon's centroid isn't always effective. A more elaborate algorithm is needed.

@Steven P, I think the @Mountain_XD want to draw a rectangle between two selected points in that way the rectangle will be drawn inside the yellow polylines (I think that is walls) at desired height (T) in total length between two selected points. I think I understand correctly based on drawing.

Dear @pkenewell, thank You for help, it works like a charm Best greetings M

Use DATE instead of CDATE: https://help.autodesk.com/view/ACD/2023/ENU/?guid=GUID-CBB24068-1654-4753-BE2E-1D0CE9700411 DATE stores the date value as a Julian date, which simply counts the number of days which have elapsed from a given epoch - as such, you can easily subtract two integer Julian date values to calculate the number of elapsed days between two dates, e.g.: (< 7 (- (getvar 'date) (atoi (getenv "TELNUMBERS")))) (assuming you have changed TELNUMBERS to store the DATE value instead of CDATE)
