Selecting all lines from same layer that have the same suffix

[marius.lechtenboehmer]

I have contour lines (polylines) with a precision of 0.25m. So 1.00m, 1.25m, 1.5m, 1.75m, 2.00m, 2.25m etc. They are all on the same layer. I want to select all the lines that have the suffix .00m (1.00m, 2.00m, etc.). How do I do that?

Using the quickselect feature and writing "*.00" doesn't work.

Hi,

Do you mean polyline with line weight 0.25mm?

drop some .dwg

No. All lines have an attribute names "height". I want to select all lines from the same layer that end with .00 on the attribute "height".

Doesn't work. The polylines are neither blocks nor text. In the screenshot it is the attribute "Erhebung".

try this but you need  map3d ore civil 3d

It's "Elevation" in English. And it cannot be done using built-in features.

If you post some sample dwg I could do some quick lisp.

Here's a sample of the data. A lisp would be amazing!

I also have AutoCAD Map3D available but I guess that won't help me.

I don't know MAP, but C3D will definitely helps since you can set styles that differentiate contours (eg by layer)

(defun c:SelectContoursbyElevation ( / m s r i e)
  
  (if (and (or (and (ssget "_I")
		    (sssetfirst nil)
		    (setq s (ssget "_P" '((0 . "LWPOLYLINE")))))
	       (setq s (ssget '((0 . "LWPOLYLINE")))))
	   (setq r (getreal "\nRemainder after division 1: "))
	   )
    (repeat (setq i (sslength s))
      (setq e (ssname s (setq i (1- i))))
      (if (not (equal (rem (cdr (assoc 38 (entget e))) 1) r 1e-9))
	(ssdel e s))))
  (sssetfirst nil s)
  (princ)
  )

That is awesome! Thanks a lot. Works like a charm.

You can also try ELEVLAYER.

It puts objects at certain elevation to a specific layer. Then you can use layer filter to handle them in groups.
