Selection set by window selection

Anonymous — Fri, 25 Sep 2020 20:50:07 GMT

I am trying to create a selection set by selecting entities by a window. i thought it was

(prompt "\nSelect Objects by Window")
(setq p1 (getpoint "\nFirst Corner: "))
(setq p2 (getpoint p1 "\nSecond Corner: "))
(setq ss1 (ssget "w" p1 p2))

i am having some trouble though. I must be missing something & just not thinking of it.

What is the feedback after the 4. line?

(copy paste the line to your commandline)

Then [F2] to see the feedback

If it is not "nil"

Start move command and select the items by type in P<enter>

What is your product/version?

Are the objects visible?

fully inside the window corners of p1 and p2?

[EDIT]Using a english version?[/ EDIT]

This works for me in 2012. Are you using an English or International version of AutoCAD?

I'm using vanilla AutoCAD 2016. United States English version. Its just a floor plan consisting of lines, & some blocks of windows, doors, etc. I'm trying to create a selection set by selecting the objects with a window. I get a dashed single line when I try to run it instead of the window selection I was expecting

To me, that sounds like maybe you're viewing the whole situation edge-wise to the current Coordinate System. If you do UCS World / PLAN World, does it still do that?

This is caused by collecting the preselecting the points p1 and p2 using getpoint. Try just using

(prompt "\nSelect Objects by Window") (setq ss1 (ssget "w" (getpoint) (getpoint)))

So is this your "trouble" ? It works (object selection), but you want this dashed rectangle?

LOL, then i missed your point, sorry.

Maybe i should tell you guys what i'm trying to do. i will have a drawing open. The routine will get every multileader in the drawing & explode them. It will then select some entities with a window & then change the color of all entities to the white color. It will then wblock those entities to the directory that the drawing is open to naming it pool.dwg. It will do the same thing to a second bunch of entities naming that pool2.dwg. i found a Lee Mac routine on one of the forums that handles the multleader part, but i'm having trouble with the window to select the entities. Finally it will undo back to the point where the multleaders are exploded making the drawing look like it did with the routine was run. i am attaching the file.

If you want a box as input you need a GRDRAW box function to temporary draw a box , other way is use rectang and get max min cnrs.

Need to google draw a box.

Look at yinyang I am sure there is a draw box some where. https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/grread/td-p/2706707

i mostly want to be able to select the entities. I was just expecting it to be a window selection. much like if i just typed change properties into the command prompt it asks me to select the objects.

(prompt "\nSelect Objects by Window") (setq p1 (getpoint "\nFirst Corner: ")) (setq p2 (getcorner p1 "\nSecond Corner: ")) (setq ss1 (ssget "w" p1 p2))

Also you can use command SELECT, and after that you have selection set as:

(command "Select")(setq ss (ssget "p"))

Just curios, why simple

(setq ss (ssget)) is not enough?

That allows you a window selection within dashed rectangle... what am I missing?

It is just enough to create selection set.

I was getting an error message when i tried that originally. It turns out that the area i thought was creating the problem was not correct. Right after the selection set i want to change all the colors of the objects selected to color white. The code that i had is (COMMAND "change" ss1 "p" "COLOR" "7" ""). This seems to be causing the error.

I am attaching the error i am getting. After that i want to wblock that same selection set to the directory that i am working from

you still need to close the ss

hmmm. It doesn't seem to be running the change command. I wonder if i need a progn statement or something.

(prompt "\nSelect Objects for Pool.dwg by Window")
(setq p1 (getpoint "\nFirst Corner: "))
(setq p2 (getcorner p1 "\nSecond Corner: "))
(setq ss1 (ssget "w" p1 p2))

(COMMAND "change" ss1 "" "p" "COLOR" "7" "")
