AutoCAD LT :: Hatch As Closed Element
Jun 1, 2012
I've just made the dramatic leap from AutoCAD LT 2005 to AutoCAD LT 2013. By far and away the environment in 'Classic" mode is very familiar and there are some new features. However, one item really getting under my skin is the hatch feature. In LT 2005 one could pick the points to hatch, if the item is closed or not, by individual mouse click points similar to how you can still check an area now. Is this hatch feature still available and I just don't have the new program configured properly or will I be forced to draw each item I want to hatch as a 'closed' element?

I am trying to find a command that will hatch the inner edge of a complex closed poly line, rather than hatch the entire area inside the poly line.
When I have simple shapes such as a rectangle I create a smaller rectangle inside the first that is 1' (or whatever I want my hatched area to be) smaller on all sides than the first rectangle. I hatch by selecting the two rectangles; I change the "Associative" hatch property to "No" and then delete the inner rectangle.
My problem now is that I have a complex closed poly line that I would like to hatch the inner perimeter with a set thickness, say 1 foot. Is there an easy way to hatch a inner boundary of a closed poly line or to recreate a scaled down copy of the poly line that is a set distance smaller all around. I hope I have conveyed the question clearly enough.

Basicaly I have a plan of a part of a city and I want to fill the houses with a solid hatch, I was wondering if I could do them all at once instead of picking an internal point one by one (there are a lot of them!).

My goal is to write a Drawable Overrule, which would change the entities color to dark gray, except when they are on a specific layer. For closed-only curves in this layer, I want to add a semi-transparent hatch.
All works great, until user moves the mouse over this hatch : AutoCAD throws a fatal error and closes. I've no exception in debugger...
When I remove the code concerning the hatch, I've no error at all.
Public Class ClosedCurveDrawableOverrule Inherits DrawableOverrule Public Const HighlightColorIndex As Short = 1 'Color Red Public Const BaseColor As Short = 251 ' Color DarkGray Public Const SpecificLayer As String = "Layer1" ' Set our transparency to 50% (=127) ' Alpha value is Truncate(255 * (100-n)/100) Public [code].......

I have a line drawing from a draftsman. It was imported from some other program, but I'm not sure which. However, this has cropped up many times over the years on my drawings as well as others. It just is typically quickly remedied with a workaround.
The hatch spacing too dense issue requiring me to break up the area: this problem will occur on equally sized areas at the same zoom factor at which I just hatched an adjacent area. I have changed the "MaxHatch" variable environment from stock at 10k, to 100k, then to 1,000k; yet the problem persists. I don't have a particularly fast machine so by that point I decided there was no need to max the variable at 10,000k. There are no z variables in the drawing though it appears, almost randomly, to have plines or lines along the same length of wall.
The second issue is the closed boundary. This occurs on lines that are connected at all corners, even when I stretch and reconnect a line, though that is a very time consuming method. When I increase the hgaptol variable it will hatch bizzarre areas that have no relation to what I am attempting to hatch. This is also occuring even inside a REC that I created just prior to hatching due to error on the original layout. I have to hatch an object rather than select an internal point. It has become so obnoxious in this drawing that I decided to post with these questions.

I have used PEDIT to join multiple polylines, which now appear as polylines. But when I use QSELECT to show all open (non-closed) section, one polyline still shows up as open.
I've attached the file I'm working on. The polyline in question is the green outline on the object on the right.

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
name: 7efc7c10>) (5 . "737") (100 . "AcDbEntity") (67 . 0) (410 . "Model") (8 .

[code]....
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 have a hatch (ANSI31) enclosed by a closed polyline. Whenever I change the hatch from ANSI31 to GRAVEL some of the hatch shows up outside the boundary. The Polyline consists of both arcs and line segments, and the hatching errors are occurring within the radius of the arc segments. Changing it from Associative to Non Associative makes no change.
I am using AutoCAD 2011.

Just downloaded Autocad 2013 and am missing quite a few of the standard hatches (siding, soldier, board and batten, etc.) What should I do to get them back. When I open old drawings with these hatches in them, they load just fine...but I am unable to hatch any new areas with these hatches (because they are not listed in the hatch library)

I want to be able to add a Block Reference to a hatch. I'm adding the block reference to an ObjectIdCollection and the hatch is not taking it when using AddLoop().
So I thought maybe I needed to add the location of the polyline (curve-like) object that is member of the blockreference to the hatch, but I don't know how to get its ObjectId.
Hatch thisHatch = new Hatch();thisHatch.Layer = layerName;thisHatch.SetDatabaseDefaults();thisHatch.SetHatchPattern(patternType, patterName);thisHatch.Color = Color.FromColorIndex(ColorMethod.ByColor, colorIndex);thisHatch.Transparency = new Transparency((Byte)(255 * (100 - 60) / 100));tSpace.AppendEntity(thisHatch);transaction.AddNewlyCreatedDBObject(thisHatch, [code]........
Also, I'm trying to delete certain HatchLoop that is associated to a polyline but I don't know how to do it. I'm going through the loops in the hatch but I don't know what to do there. I wanna do this so I create a new and different hatch on top.
I think one could also copy all the loops except the one one wants to delete, but I'm not sure how to tell which one is the one I want to delete that is the one associated to a polyline or that is in certain region.

I have AUTOCAD LT 2012 - windows 7 - SP1
Neither the button for Hatching or the Draw Hatch menu do not activate the HATCH DIALOG BOX?
This means I cannot Hatch?
I have also added the Hotfix for the Ribbon and it made no difference.

I've migrated from 2005 to 2014 LT and wondered if they have added to the hatch commands. I've looked and haven't found anything. Is there a command that you can pick a hatch pattern already shown on the drawing and make that pattern the existing one to use? I sometimes have multiple hatch patterns and scales, and wanted a quick way to go from one to another without lisp help.

I have an error that started appearing in my VBA programs since we upgraded to AutoCAD 2012. This problem never occured in our previous releases. The program is supposed to loop through all entities in paperspace and check for entities that are a acBlockReference object.
Below is a simplified version of my program. I get an Element Not Found error on the line noted. Again, this has never happened in any of our previous versions of AutoCAD. Just started with 2012.
Sub Test
Dim blkref As AcadBlockReference
Dim entry As Variant
For Each entry In ThisDrawing.PaperSpace
If entry.EntityType = acBlockReference Then ' <-This is where the Element Not Found error occurs
msgbox entry.name
endif

I’ve got a student version (AutoCAD for Mac 2013) , which I got from official website. There starting to appear few problems after a few months of my work.
1. when I’m doing a rectangle, lines that intersect or just lines that contact, in the point of connection appear small blue rectangles and windows of mistakes. If I trying to move only one element of this object, all others elements start to deform in chaotic way.
2. when I’m coping any object on the same page in one file, program start to buzz and I need to close the program despotic.

I'm having problems creating the element in DBTEXT BackgroundWorker in VB! Develop a function to create the element dbtext in the current document, when I use this function within <Autodesk.AutoCAD.Runtime.CommandMethod("")> it works perfectly, but when it is used within BackgroundWorker raises the point of different alignment indicated. And the problem is solved when you run the AUDIT command in the project, then the alignment points are corrected. The same problem is occurring for the blocks that have attributes, in this case the alignment points are also displaced the attributes of the standard indicated.
Public Function NewDBText(ByVal InsertPoint As Point3d, ByVal Rotation As Double, ByVal LayerName As String, ByVal ForceColor As String, ByVal AttacPoint As AttachmentPoint, ByVal TextValue As String, ByVal Height As Double) As ObjectId Try Dim DBTextBase As New DBText DBTextBase.Rotation = Rotation DBTextBase.Layer = LayerName

How can I alternate the element selection if both elements are on top of each other? I tried to mouse click on the lement with alt or control keys but nothing worked.
Example. I drew a construction line then I drew the line I want to keep on top of it. Now I am trying to delete the construction line but the new line keeps highligting.

I have not come to a solution for creating DBTEXT elements within a BackgroundWorker, this element has problem with the alignment point. So there is an example ZIP, just run the command and check the elements created, you will see that I'm creating the element with the point in alinahmento MIDLECENTER but the result is not correct.
I am creating other elements in the same way and they had no problems (MTEXT, POLYLINE, CIRCLE, SPLINE, LINE, etc. ..), they are correct, but the element and the element DBTEXT block that contains attributes present problems in the alignment points.

I know that I can assign transparency to an element (even to an entire layer). But is it possible to apply transparency to an element on a GRADIENT basis? In the following image, I'd like to have the portion between the outer boundary of the gray shape and the red shape become more and more transparent. So that at the outer edge, you'd see NOTHING below the gray shape--but the closer you get to the red shape, the more you'd see through the gray shape.
