Is it possible to include a point entity (rather than a zero-length line as in the standard SQDOTS pattern) in a custom hatch pattern?
If so what's the exact format of the line in the .pat file that defines the point?
I am trying to entmake a hatch entity from a hatch template.
After entget the template hatch entity, i get the followings
Select object: ((-1 . <Entity name: 7ed11b78>) (0 . "HATCH") (330 . <Entity

Now I wrote the following code using the above data as follows
(entmake (list (cons 0 "HATCH") (cons 67 0) (cons 410 "Model") (cons 8 "SECTION-LABEL") (cons 62 255) (cons 10 (list 0.0 0.0 0.0)) (cons 210 (list 0.0 0.0 1.0)) (cons 2 "SOLID") (cons 70 1) (cons 71 0) (cons 91 1) (cons 92 1) (cons 93 8) (cons 72 1) (cons 10 pt1) (cons 11 pt2) (cons 72 1) (cons 10 pt2) (cons 11 pt3) (cons 72 1) (cons 10 pt3) (cons 11 pt4) (cons 72 1) (cons 10 pt4) (cons 11 pt5) (cons 72 1) (cons 10 pt5) (cons 11 pt6) (cons 72 1) (cons 10 pt6) (cons 11 pt7) (cons 72 1) (cons 10 pt7) (cons 11 pt8) (cons 72 1) (cons 10 pt8) (cons 11 pt1) (cons 97 0) (cons 75 0) (cons 76 1) (cons 98 1) (cons 10 (list 0.0 0.0 0.0)) (cons 450 0) (cons 451 0) (cons 460 0.0) (cons 461 0.0) (cons 452 1) (cons 462 1.0) (cons 453 2) (cons 463 0.0) (cons 63 5) (cons 421 255) (cons 463 1.0) (cons 63 7) (cons 470 "LINEAR")))
The point variables pt1, pt2....pt8 are all defined. But when I run the code the hatch is not being created? Why?
I need to let the user pick on an entity to get an elevation.
I was using getpoint, with osmode set to nearest, but it allows them to pick 2d items under the 3d items I want picked.
Without doing fancy laer manipulation to turn off 2d stuff, are there any tricks to avoid snapping on the 2d item?
I am thinking I might do an entselp, then try again at same point until i get a 3d one (non 0.0 z coord).

I am looking for some code that would allow me to select a MTEXT Entity - or other entity - (as the DEFAULT option) but also to allow me to type in some text manually or to pick a point in the drawing. Something that would present the user with:
"Select an object or [P to pick a point]" or
"Select MTEXT or [M to type].
I can write some code to type in text manually as the default option and get the second option to select entity using get string and then write some condition of if code but I don't know how to do it having entsel as default option.
Basically I have one hatch pattern that was used at different UCS values. The hatch patterns are correctly shown on the screen as shown in the attached image. But the puzzling thing is that they both have a pattern angle of 0.
I have been writing a program that globally changes hatch patterns, but the problem is that once I update the pattern, they all have the same angle. I need them to keep their current rotation when the patterns are updated. I cannot seem to find object access to what that actual angle is.
vla-get-patternangle does not seem to provide the data I am looking for.
I'm trying to create a hatch pattern to match a floor tile. I want a 24" long x 6" wide plank tile. The tiles should be offset from each other 8" (a 2/3 1/3 pattern lengthwise). My problem is I only can get a 6" offset (3/4 1/4 pattern).Here's the code I've got:
0, 0,0, 0,6
90, 0,0, 6,6, 6,-18
i'm newbie in customizing tools in autocad especially in creating hatch pattern. i understand that to create new hatch pattern is by adding a new hatch pattern in acad.pat file with specific angle.
my question is is it posibble to create a hatch pattern that can use specific angle follows the object shape?
This is what autocad can do by default this is what i'm trying to create
I am in need of a lisp routine which will automatically pick up all hatch and solid hatch patterns within a drawing and change the colour to colour 254.

how to draw a text entity in 3d, where I know the 3d ins point, and the plane it should be flat to.
I have not drawn text or inserted blocks programatically before where the plane they lie on is not flat.
I have done it before by setting a ucs and drawing stuff, but now I want no switches of UCS involved.

presuming I have a selection set of different entities, that might have different linewight.
The code that is responsible for this property is 370
370Lineweight enum value. Stored and moved around as a 16-bit integer.not omitted from here
I need to make all of the entities have the same layer, and to make sure the each entity has the "ByLayer" lineweight.
The problem that I encountered, is the lineweight changement.
This is the colution that I came with, but it doesn't work for me:
(defun c:test () (setq en (car (entsel))) (setq el (entget en)) (setq el1 '()) (setq indx -1) (repeat (length el) (setq indx (1+ indx)) (if (/= (nth indx el) (assoc 370 el)) (setq el1 (cons (nth indx el) el1)) ) ) (setq el el1) (entmod el) (princ) )
Having tested it in different ways, it looks like at the end, el1 represents the association list that I want my object to have, but it doesn't want to update.
I need to return the entity name of the largest (longest closed) polyline in a selection set. At this point I have no trouble creating the selection set and even getting the area of the boundingbox, which is not the most accurate way to find the true size, but it's a start. The part that has me stumped is: if I iterate through the selection set, then how can I compare one to the other when I have access to the current entity. I've been staring at examples of lambdas but it seems to me that iterating through the selection set is going about it wrong in the first place.
Below is my current code with a remaining issue. I can return the largest area of the polylines (no good for more than two entities in selection set), but I do not know how to return the entity name:
(IF (> (SETQ SS (SSGET "x" '((0 . "*POLYLINE") (8 . "POOL") (-4 . "<OR") (62 . 5) (62 . 256) (-4 .

I know you can modify a vertex, but what about add and delete with entmake and entmod? I also considered using activex for this task, but you can only add verticies from what I could tell in the object browser of VBA, not delete them.
What I will be doing is deleting all the verticies and adding back the correct ones. Or if there was a way to transfer a handle to a new entity after deleting the old, that would suffice too.
I have a Lisp that I have been working on with some folks in the office, and i feel like i am close, but i am not getting the cigar. The idea would be to have the lisp allow the user to select a nested x-ref entity, and change the color and linetype of the selected layer, similar to the old "LAP" command (I know it is a dinosaur, but I still miss it). I seem to be doing swimmingly, code I have quasi-plagiarized. It seems to crap out where i try to pass the selected linetype back to the layer. I get the nastygram "Command: ; error: no function definition: GETLINETYPE" right after selecting the linetype from the dialog.
Code below...

is there a way to convert multiple 2d solids to hatches.
View 9 Replies View RelatedLisp that can select all hatch in a drawing with a layer called AELE, even if it is embedded in a block and change it to layer AHAT with Green colour?
The layer AHAT may or may not already exist in the drawing.
We need to run the lisp on a lot of drawings (exported from Revit) so I need to use the script to run this lisp on multiple drawings.
I'm looking for a lisp routine which will 'convert' number of 2dsolid into hatch. Drawing contains dozens of 2dsolids (solids are on one layer, there are also other entities on this layer) which have different colors, have common verticies and edges. i.e. I want to kind of 'join' solids of the same color and convert them into one hatch colored as original solids and placed on existing layer (let it be layer '0' zero for now). Same color solids can exist in few locations - there is a case to make few separate hatches of the same color (all joined solids should be represented as 1 hatch, should not separate after separate hatch command). There is max of 20 different colors (all of them from ACI index). Solids are not crossing themself or other solids (just joining with 1 or 2 verticies).
There are also 2dsolids with 'zero-area' - represented as a line - those should be erased at the beginning (not to have a line-like hatch).
Example drawing attached.
I have the following code to delete all hatch in a drawing. At the end of the command there is a notice that all hatch have been eliminated.
However, the last message displayed is: "Hatch boundary associativity removed".
(defun c:deletehatch ( / d l )(vl-load-com) (setq d (vla-get-activedocument (vlax-get-acad-object))) (vlax-for a (vla-get-layers d)(if (eq :vlax-true (vla-get-lock a))(progn(vla-put-lock a :vlax-false)(setq l (cons a l)) ) ) ) (vlax-for b (vla-get-blocks d)(if (eq :vlax-false (vla-get-isxref b)) (vlax-for o b (if (wcmatch (vla-get-objectname o) "AcDbHatch")(vla-delete o)) ) ) ) (foreach a l (vla-put-lock a :vlax-true)) (vla-regen d acallviewports) (princ (strcat "All HATCH have been removed")) (princ))
Modify the attached lisp I found in this forum to work using a different hatch pattern, scale and angle. The new hatch should be in default Autocad "LINE" pattern and angle set to 90 degrees (vertical). If possible, I would like the angle and scale to be editable.

I need a function that allows to convert the polylines selected with a width globalize defined in a double closed line (spaced by the same width of the polyline), with a hatch inserted automatically defined.
Brilliant idea to draw raceways quickly: instead of making handmade double lines, connect, enter the hatches all by hand, you could quickly draw the polyline with width identical to the size of the duct, and then the lisp transform it into a duct more aesthetically pleasing if compared to the full polyline!
