setting layers based on object selection

shillmanB5QQZ — Fri, 18 Dec 2020 20:06:32 GMT

Definite LISP newbie. This is my first. I know, big undertaking. I have been working this lisp routine that you select the wall, select point on wall for the start of the break, select door width and a point on perpendicular line and it will break both lines and draw the ends of the walls in on the correct layer, and inserts the door block on the correct layer. I have 4 possible scenarios for the wall layers, (EXST-WALL-INTR, EXST-WALL EXTER, NEW-WALL-INTR, NEW-WALL-EXTR) and 4 scenarios for the door layer (EXST-DOOR-EXTR, EXST-DOOR-INTR, NEW-DOOR-EXTR, NEW-DOOR-INTR ) I have accomplished this task . . . . to an extent. I have figured out setting the wall layers. The issue is having 4 possibilities of door layers based on what wall layer is picked. I have made 2 lisp routines, one for existing and one for new. I would like to have one routine for all scenarios. I am wonder if there is a way to to have one routine (Door.lisp) that can process all existing and new conditions and set appropriate layers. I have found help from various sites on the internet to put this routine together but can seem to find an answer to what I am looking for. Hence the reason for this post. Here is what I have found, pieced together and figured out so far.

;Program to cut door opening in wall and insert door on correct layer -- DoorExst.lsp

);end extr

);end if

(princ)
);end doorexst

Any help would be greatly appreciated. Also, I know the structure is probably less than desirable. All suggestions on lisp structure are welcome as well. New to these forums, if this needs to be move to a more appropriate location feel free to move.

Thanks in advance,

Why don't you just install and run AutoCAD-ARCHITECTURE? Its free with every AutoCAD subscription for the past 2+versions now, it does all that, plus so much more, and you get actual smart doors/walls/ceilings/roofs etc. to boot.

Are you able from layer of breaking wall tell the layer of door? Like

Do you still need to decide whether its interiour or exteriour? Isn't it given by a wall layer?

Re: setting layers based on object selection

shillmanB5QQZ — Fri, 18 Dec 2020 21:31:33 GMT

Yes in this program selecting the wall sets the layer for drawing the ends of the walls at the cutout and determining whether the existing door goes on an interior or exterior door layer. Where I am running into trouble is with the new door layers. Being that I am very new to writing lisp and I am having a problem with how to incorporate the NEW doors into this routine. Currently I have one lisp file for existing doors and one lisp file for new doors.

Not sure if I do follow... I thought it's all given by layer of cutting wall. anyway, try the code and see...

BTW don't you want to incorporate the doorsize too?

Yes! I would like to incorporate door size and openangle, which are both dynamic values in the door block.

Now you show up. Find the line causing this trouble!

btw it works for me.

Here's the code. I'm not versed with imperials... so test it yourself better.

Also, have a bit issues with degree sigh of yours... "Closed" vis state works, but not the others. Either find and use the ascii num or rename the states. Good luck

Thank you for the help. All the layering is working great. I am having issues with the "OpenAngle" value of the door block, and the rotation angle during block insertion. I tried making some adjustments to the lisp and totally messed up the routine. Here is what I am getting when I try inserting a door on any angle wall other than a horizontal wall.

Thanks again!

Re: setting layers based on object selection

Kent1Cooper — Mon, 21 Dec 2020 16:36:44 GMT

I am looking at this line:

(command "-insert" "door" pt3 1 1 ang2)

which includes both X and Y scale factors. When I Insert your Door Block manually, even though it doesn't claim to be defined for uniform scaling, as a dynamic Block it wants only one. The ones in your sample drawing have rotation angles listed in Properties at the directions of the wall Lines, but something about their being dynamic must be why they don't look like it. [I'm not well versed in dynamic Blocks, so others could advise better than I.]

At least try taking the second scale factor out:

(command "-insert" "door" pt3 1 ang2)

Re: setting layers based on object selection

shillmanB5QQZ — Mon, 21 Dec 2020 17:43:43 GMT

Thanks Kent1cooper, I redefined the block to scale uniformly and took away a "1".

(command "-insert" "door" pt3 1 ang2)

Now when I run the routine the first door (horizontal wall) is inserting correctly, 0 rotation. The second door I inert, the one in the angled wall, is inserting at a rotation angle of 1 instead of "ang2", and the third time I try and insert the door (vertical wall) the door inserts at a rotation angle of 2 degrees.

Also, the "AngleOpen" value in the block is not working either. The prompt is only reading 90, closed. 90 is not working closed is working. The prompt should read " 30, 45, 60, 90, Closed". If I try and change that the routine fails to work. Sorry to be such a pain. I have not worked with either of the "OR" function, the "COND" function nor the "nentselp".

Thanks again!

Very bizarre!

On that issue, they're not at 1 and 2 degrees -- those are only rounded-for-display values. [This is why I never have angular values displayed to the nearest whole degree.] They are the directions of the Lines, in degrees but with the numerical value of the angles in radians. If you're using @ВeekeeCZ 's code, ang2 is still in radians when the Insert happens. Your original had a multiplier to convert the angle between points to degrees [there's a more precise way, but that could be close enough for your purposes].

I expect if you typed in one of those other values, it should "get" it. But to be able to pick them from the prompt, they would need to be included in it, something like:

..."\nOpening Angle [30/45/60/90/0/Closed] < ....

[I haven't fully traced through what that gets used for.]
