I select all entities via Editor.SelectAll() method, but the nested entities (inside Blocks) are missing. Do I have to resolve them by iterating through all blocks afterwards or is there a Prompt Selection Option that can be set?
I don't want the user to select the entities, instead I loop through the whole drawing.
How to select all entites of a layer?
I want to migrate my VB code to VB.NET code, migrate the below code?

I need a function similar to Qselect.
In this case I would like to select all entities on a series of layers. (i.e.: a-site-* or a-fill*). I know I can do this with qselect by doing each layer one at a time and append the existing selection set.
Instead, I've been locking all layers except the series I'm looking for, but it seems like there should be a quicker way.
I have a command which proccess entities in the drawing and creates a SelectionSet. But, on the drawing i do not see the selected objects . I need to show grips on selected objects . It is a looks like a Quick Select command. What can i do? What method showing the grips?
View 2 Replies View RelatedI coded a utility to work with entities rotation. This is a part of a bigger project so i just cutt and pasted together the part of code that have this problem.
Basically i get the selection, i clone it (because this is a copy and rotate) and through a draw jig class i rotate all the entities. This works well but just sometimes when the command ends it happened this weird thing, the entities appears in the draw but they can't be selected. And all get back to the normally after saving, closing and reopening the draw.
This is the utility.
public void Run(object param) { Document doc = Application.DocumentManager.MdiActiveDocument; Editor ed = doc.Editor; Database db = doc.Database; List<Entity> toRotate = new List<Entity>(); PromptSelectionOptions pso = new PromptSelectionOptions(); pso.MessageForAdding = "

When trying to select entities with a window or crossing polygon (and hitting enter) there are no grips showing to indicate that the selection has been completed even though the entities seem to be highlighted. Syntax: select, enter, wp, enter (draw polygon), enter.
I am a part time user of this wonderful program and only recently moved to 2010 and yet I cannot figure out what I am doing wrong. I have Googled and looked in my texts and still am having difficulty (also attempted to search FAQ on this site but the link malfunctioned).
When I select more than 100 entities all of the grip points disappear. With ACAD 2002 there seemed to be no limit to the number of entities you could select without losing the grips, but with ACAD 2007 they started dissapearing though with '07 clicking "View" "Regen" would bring them back into view (unless you accidentally click on another entity). With ACAD 2013 if I go over 100 that's it. This is mostly a problem for me as I use the spacebar shortcuts extensively in creating and manipulating my drawings. I have found other ways to to acomplish my needs such as using the move command but I have much successful history using my old methods and would like to continue with them.
View 3 Replies View RelatedThe 'application' I am trying to make currently adds entites to a drawing. Each entity has data associated with it but also part of a tree of infomation so I store xrecord data along with the objectID in a dictionary tree within the drawing.
I want to be able to select multiple entities and have any matching data shown in a palette. The same way the properties palette behaves.
I have it working but I can see AutoCAD crunching the data. It cycles through the selection set and the dictionary tree extracting entity data until it finds an ID match in the xrecord.
How the properties palette works so quickly or how I could improve the speed.
We have this need to have all of the solids in a drawing to be placed in the "solid" layer.
Sometimes folks are drafting lines to develop these solids, and keeping the lines on the "solid" layer, rather than moving them to another layer, or deleting them altogether.
I could get folks to run this command before leaving the drawing.
I'm thinking something along the lines of:
Select all entities that are on the solids layer that are not solids.
If nil, great, do nothing.
If entities are selected, let me do something with them.
I'm hoping the following can be modified ever so slightly.
(setq non_solid (ssget "X" (list (cons 0 "3DSOLID")(cons 8 "solid"))))
My Zoom Extents isn't working right and when I try to plot it says, "No extents in drawing. Could not set plot area to Extents." If I hit OK and go to the Plot Window, Extents isn't an option for the Plot Area and the Plot Scales are way off. I have never seen a drawing that didn't have an extents?

I'm having a problem with Zoom Extent on a poticular drawing. when zooming normally with the scroll wheel it will work with no problems at all.
When I do a Zoom Extents everything in the Model window disapears even the viewcube and small tool bar and minimize and close buttons. but if i go to where the minimzie and close is and click my mouse picks up the command.
If i do a undo i get everything back.

Would this be a system varible or a driver issue. it only seems to do it with this drawing and when this drawing is Xref'ed into another drawing.
I have purged, audit and checked scales. but i'm still getting this problem.
I am exporting shape files for a GIS user. I am using the correct coordinate system and my units are in feet and decimal degrees. I can export the lines and points with attributes and they import into GIS just fine. When I export a polygon with or without attributes, when i import them into GIS i get the error "One or more of the added layers has an extent that is not consistent with the associated spatial reference."
View 3 Replies View Relatedlooking for a way to read in the DXF data for a surface entity in AutoCAD2012. There's plenty on reading in simple objects (e.g. 3DFace, Points, etc.) but nothing on surfaces. The data itself is also not as intuitive as I would have hoped. The DXF reference PDF from AutoDesk shows 7 possible unique entries and the data I need is most likely stored in the proprietary data. So, in short I know where it is but how can I read it?
View 7 Replies View RelatedHow could I get the ObjectIdCollection of all entities (points, polyline) in a certain layer?
I am using the following code at this moment.
private ObjectIdCollection GetEntitiesOnLayer(string layerName)
{
Editor ed = doc.Editor;
TypedValue[] tvs = new TypedValue[1] { new TypedValue((int)DxfCode.LayerName, layerName) };
SelectionFilter sf = new SelectionFilter(tvs);
PromptSelectionResult psr = ed.SelectAll(sf);
[code]....
But it seems the function fetches more ObjectId than I expected.For example, if I draw 3 points and 2 polylines in "A" layer.
ObjectIdCollection obc = GetEntitiesOnLayer("A");
int i = obc.Count;
I was expecting i to be 5 (3 points and 2 polylines), but i seems to be more than 5.
I have the dialog window with the settings for entities graphical appearance used in my plugin.
My goal is to create the same preview as AutoCAD dimension style manager dialog has, the dynamic thumbnail of the entities while user changes the settings in dialog.
Probably one option is to create temporary block (created based on data from settings dialog) and then use BlockTableRecord.PreviewIcon, but I am not sure if there is some other way.
I have a requirement to find all connected entities on a given line of a plant P&ID. In other words given a certain line or reference point the requirement is to 'walk the line' and list off all entities (with certain attributes and in order) that are connected on a line.
Now not having any experience with underlying object models and API's, whether A) this is possible B) which object model to use - I'm a bit confused as to which one to use.
I received a drawing from an outside contractor that uses something with proxy entities. I can see them just fine on the screen but when I try to plot the drawing they disappear. It also came from a newer version so I had to use the DWG True View to convert it if that may have caused my issue.
View 5 Replies View RelatedI'd like to automatically hatch all visible polygons of a drawing. My vision of how to solve this is basically:
- for each visible drawing do
- pick internal point
- hatch
- end for
I'm having trouble by automatically picking an internal point inside the polygon.
I've found these two methods : Crossing numbers and winding numbers [URL]....... but they don't seem to work if there are some polylines inside an polygon.
Is there another solution to my problem for automatically picking an internal point inside a polygon ? Can I automatically hatch an polygon without picking it's internal point ?
My code takes the selected entities and reads out all the text of the attributes.
If no blocks are selected, the code prompts for a selection.
Unfortunately, by ending the transaction, the entitis are deselected.
So how to keep the selection, because it will be handled in a follow-up step.
Below a shortened code for the procedure:
private void Get_Text(){ Autodesk.AutoCAD.Internal.Utils.SetFocusToDwgView(); PromptSelectionResult sel = edt.SelectImplied(); if (sel.Status == PromptStatus.Error) { TypedValue[] auswahl_typ = new TypedValue[] { new TypedValue((int)DxfCode.Start, "INSERT") };

I try to get all current entities for my own custom palette.
I tried it with ed.SelectionAdded and ed.SelectionRemoved but it doesn't work if I for example pressing ESC.
I want to get the Object Ids saved in a ObjectIdCollection and I don't want to run an autocad command every time.
I wrote a program that trys to move all the entities in a dwg file by calculating a grid transformation for each point in each entity. For example to move a pline
Case Is = "AcDb2dPolyline"
Set o2DP = oEnt
retCoord = o2DP.Coordinates
For j% = 0 To UBound(retCoord) Step 3
yaa# = retCoord(j%)

My problem is moving hatch entities. I haven't succeeded in finding equivalent code to move the hatch entities. I did find another post here, but I still don't get it.
Just a follow up to the inquiry on the Flatten command. Is there a way to use set all entities in a drawing to elevation 0? like moving them all to Z=0 like the flatten command but all entities in one command including blocks, hatches, etc.

How can I trim entities in an array? I can make the array just fine, but I don't know why it won't let me trim them. I suppose it's trying to keep references to the array and the original entity that the array is based off of, but at this point I don't wish to keep that information.
View 5 Replies View RelatedI have some blocks which are placed with some routines in VB.net and are linked by a unique code to a external data file (XML-file). I want to try to created a kind of propertybox (in a toolpalette) which indicate some of this external data values. If one of these values are changed (by changing the values in the propertybox), some routines need to be executed.
Is it possible when a object is selected (not during a command), to run a piece of code (VB.NET). I have found some basic principles about "overruling" but I'm not sure this is the correct/possible way to solve the problem and I'm not there yet.
What i want to do is popluate a Listbox with with the area of previously selected Objects.This is what i have at the moment:
i = 0ListBox1.ColumnCount = 2For Each ssetOBJ In sset objarea = ssetOBJ.Area i = i + 1 With ListBox1 .AddItem .List(.ListCount - i, 0) = "Fläche" .List(.ListCount - i, 1) = objarea End With Next.
But the code only writes the area of the last Object in the first Row of the Listbox.I think in the FOR EACH Expression the variable "i" pass always "1" for the Row Number.
I'm try to set a classification for a list of objects with .net. I'va found some discussions regarding changing and iterating classification trees, but none setting the classification for entites, similar to selecting a classification in ui.
View 1 Replies View RelatedWe're having a problem with Ordinate dimensions. When we dimension to a radius corner, we dim to the "implied intersection" of the two lines, rather than to the center of the radius. We make a sketch with the two "tick marks", then dim to the intersection of the tick marks.
Ordinate dimensions are not allowing us to pick the intersection: it wants to put two (or three) dimensions, one to each end of one or the other tick marks (see attached). We use Ordinate dims about once a year, but I'm sure I remember being able to ordinate dimension to the tick marks.
