AutoCad 2D :: Object Instance Calculator
Jan 30, 2012
I have created a block which contains various part numbers, with a description and some other bla bla, with a total number box, I issue this to clients to make the specification of product much easier. My idea was for people to use the quick select command to find how many instances there is of an object within the drawing.
As this is a slightly tedious process, as you have to physically type the part number then mentally take one instance off as it counts the number in the legend block as well.
Is there an addition/summary of object instances command I could use to make this process more dynamic and straightforward for the recipient/user of the block I issue?

I get the following exception message while debugging, after pasting VBA code into my vb.net project:
"Object reference not set to an instance of an object"
Without going to specifics yet, I commented-out ObjectCollections and the error happened further down in the class.
Is there a different way ObjectCollections are handled in a vb.net class, versus a VBA module?

I've just changed a VS compile options to use .NET Framework 3.5 (previously Framework 4).
My user controls that I've added as containers for the pallette don't seem to agree with it and I get a "Object reference not set to an instance of an object" error on each of their resx files. And one on Resources.resx.
Attached is a screenshot.
Is there anything I can do to fix this?

I'm getting a "NullReferenceException. Object reference not set to an instance of an object" using:
For Each SetEntry As DBDictionaryEntry In SetRootDict Dim SetEntryDict As DBDictionary = CType(SetEntry.Value.GetObject(OpenMode.ForRead), DBDictionary) Next
I have the same lines letter for letter in a different procedure and referring the same unchanged root dictionary where it works fine.

Sometimes when I drag a new symbol instance to my artboard and resize it, the instance looses it alignement with the pixel grid.
This happens despite the fact that...
I checked the box for pixel grid alignement when I created the documentthe symbol option is set for align to pixel gridthe original shape in the symbol is aligned to pixel grindthe original shape has the align to pixel grid check box in the transform panel checked
So why when I resize the symbol instance does it break the pixel grid alignmnet and result in a blurred 1px stroke?

When I try to calculate bending moment stress thru "Beam and column calcultor it shows an error that is Wk and Jk is missing. Ok that is fine. If we put values for both we will get the answer. Because I have come to know thru inv discussion that many material in the CC do not have these values.
Now my question is when we insert a part for example from content centre (CC) and do FEA analysis on this part. It shows some values like deflection, stress etc etc. How is that possible? one side it is not doing in the beam calculatio but other side in FEA it is doing that.
It means we are not going to rely upon these results in the FEA. It is the same CC, same inventor, how should be trust the result in FEA.

I am having trouble using the beam and column calculator in Autodesk Inventor. When I choose the beam that I want to test all the dimensions are not being put in automatically.
This is happening with most types of beams that I import from the CC the angle (6X3-1/2X3/8) that I am trying to test is getting no Wx, Wy, Wk or Jk. and the I beam (W6X25) is not getting Wk and Jk.

I am using beam/column calculator in the frame generator in inventor 2010 suite.I have a beam being used for a flight of stairs it is positioned 40 deg above the 'floor' or my xy plane in my assembly.I want to place a distributed load acting as if there were several people stading on the stairs at one time so in the direction of the z axis of my assembly.
The problem I am having is I try to change the angle of the distributed load but it only allows me to change the x and y components of the load.
a) change the angle of the laod in the Z directions
or
b) change the cordinates in beam itself so the x axis is along the length of the beam instead of the z axis.
I have tried adding a UCS to the beam part but it still wants to choose the length of the beam as the z axis.

I need to count the number of pixels in the white part of a person's eye. Is there a way to:
(1) Use a tool (lasso?) to select only the eye white? (an area that includes all color within a certain amount of color variation?) (Choose all the white pixels, and the slightly off-white ones surrounding the white area. The image is black and white, so color variation is solely along the white-black continuum.)
(2) Calculate the area (i.e. in pixels) of the selected area?

I used to have a DeltaE calculator which I downloaded free from the Internet, but it does not seem to be available any longer.
The idea was to type in the Lab specification for two colour samples, then the calculator would come up with the difference between them expressed in units of Delta E.
I have found a calculator which requires Photoshop CS, but I cannot locate a free-standing version.

I'had just met another matter for my Add-on. I noticed that when I instance a new drawing, while a first one is opened, when I load a new Form, this one keep all first drawing's properties. What could happen?
For example, I would like to add the layer list on a ComboBox.
My source:
Private Sub LayerBox_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load '***************************' '* Initialisation LayerBox *' '***************************' Using acTrans = acCurDb.TransactionManager.StartTransaction() acLyrTbl = acTrans.GetObject(acCurDb.LayerTableId, OpenMode.ForRead) For Each acObjId As ObjectId In acLyrTbl acLyrTblRec = acTrans.GetObject(acObjId, OpenMode.ForRead) ComboBox1.Items.Add(acLyrTblRec.Name) Next acObjId End Using End Sub
This source works, but if i instance a new form on a new drawing, the first drawing's layer list is kept and the new layer list on the second drawing is ignored!

I have a situation where it would be expedient for me to be able to bind only one instance of an xref and leaving the others intact. I have to do this for several different x-refs. Is this possible in Autocad 2008? If I use the xref manager I can only see an option to bind the entire reference.

I'm trying to insert a new instance of a X-Ref already present on the drawing. If i use Database.AttachXref(path, name) I receive "ref NAME has already been defined. Using existing definition." on the command bar. I've tried to retrieve the ObjectId of the X-Ref definition from the X-Ref name, but my code don't work. Where is the error?
Here's my
Private Sub AttachXRef(path As String, name As String)
Dim Doc As Document = Application.DocumentManager.MdiActiveDocument
Dim Db As Database = Doc.Database Dim pPtRes As PromptPointResult
Dim pPtOpts As PromptPointOptions = New PromptPointOptions("")

I've run into to some trouble when trying to create an instance of AutoCAD.
In fact, the behavior is strange, and it leads to believe it's not from creating an instance!
Anyways, I'm coming straight from VB6, so I used: Dim rpDoc As AcadApplication

I just re-installed windows and all the fine (PITA!) trimmings. Now, when I open a file (any type) for Inventor thru windows explorer it opens a NEW instance of Inventor everytime! This is a HUGE system hog, waste of time ect ect.
How can I correct this to just open in the instance that is already there?

I want to create some modules for a platform deck. The modules are made of C5x6.7 channels in one direction, L2x2x3/16 angle stiffeners in the other direction, and 3/16" deck plate on top.
My "drivable" parameters will be length and width.
The modules will all be different sizes, so I need to be able to have every instance of the assembly be different.
The workflow I was attempting to do before I got stuck was this:
1. Create a skeleton part (just a sketch) with Length and Width parameters.
2. Insert in an assembly and use frame generator to build the structural shapes (channels and angles)
3. Insert another part (the 3/16" plate) that can reference the length and width and adjust to be the correct module size.
Is there a way to make parts in an assembly all follow the same parameters? More importantly, can each instance of this assembly show up differently and be adjustable when I place these modules in my main assembly?
I don't know much about iParts - but it looks like an iPart lets you choose from predefined dimensions - I want something that I can custom input any size I need.

I have a problem creating an instance of the AcadApplicationClass. The program is very simple:
Assembly autodeskWrapper = Assembly.LoadFile(@"C:WindowsassemblyGAC_MSILAutodesk.AutoCAD.Interop17.0.54.0__eed84259d7cbf30bAutodesk.AutoCAD.Interop.dll"); Type acadAppClassType = autodeskWrapper.GetType("Autodesk.AutoCAD.Interop.AcadApplicationClass"); object m_acadDApplicationClass; m_acadDApplicationClass = Activator.CreateInstance(acadAppClassType);
and the exception is:
Retrieving the COM class factory for component with CLSID {28B7AA99-C0F9-4C47-995E-8A8D729603A1} failed due to the following error: 80040154.
AutoCAD 2013 is installed but no license is provided (there is a 30 day trial period). I am trying to launch AutoCAD.
In C:WindowsAssembly folder I can see the Autodesk interops:
Autodesk.AutoCAD.Interop and Autodesk.AutoCAD.Interop.Common. Their version is 17.0.54.0.
In Component ServicesComputersMy ComputerDCom Config I can see an enttry - AutoCAD Drawing. Its CLSID is: 6A221957-2D85-42A7-8E19-BE33950D1DEB.
I`ve read that the exception is because a 32bit process is trying to use 64bit DLL or vice versal. I have compiled my program in both 32bit and 64bit but with no results - I am getting the exception in both cases.

I've been tasked to turn our 2D cad dwgs to 3D in inventor.
I'm working on a frame at the moment, I got all the square and rectangular tube from the CC and constrained them to match the CAD dwg, now I need to add the mounting holes but if I add holes to one copy all the copies get the holes.
What option can I use to make each instance stand alone?

I would like to generate a rectangular pattern of extruded tubes which have an internal radius that is proportional to the distance to the centre point of the pattern. Or in other words tubes which are narrower in the centre, and wider at the exterior. Is there a way to do this without resorting to creating each tube individually?
More generally, is there a way to parameterise a feature dimension/parameter so that it is a function of spatial position?

A defined block "DH" has:
A circle on layer CIR having a color of red...
A defined attribute on layer ATTR having a color of white...
The insertion point is the center of the circle...
Is it possible to change the circle to blue on one instance of the block without affecting the same change to other identical blocks in the drawing? Example:

sometimes when using constraints the "movable" part is fixed after adding the first constraint.
If i use i.e. a surface to surface constraint the movable part should be free to slide on the surface.
To move the part in this case I have to add further constraint or delete the old one.
Furthermore sometimes constraints in assemblys do not update automatically. I have to click on the part and try to move it away. After releasing the part the consraint will be updated.
Are there any options to control or better change this behavior?
I am using Inventor 2013+Vault 2013.

Whenever I attempt to open a non-native format file from outside of Inventor it launches a fresh instance of IV. Currently I've been working around it by dragging the file to the status bar of IV, but at least a few times a week I forget and double click it.
Some scouring of the web and these boards yielded some info concerning this problem as it pertains to native formats, but I haven't been able to find anything for neutral formats. I'm sure it requires a registry key tweaking, but I'm not comfortable enough with regedit to go in there and just start changing stuff without some level of guidance. The problem occurs whether the files are opened from windows or an internet browser (tried firefox and ie). I suspect that every format I ever wanted to open would require a separate edit, in that case I'd be perfectly happy with just a fix for .step files. That would at least have me set for 90% of my downloads and offer an improvement to my overall sanity level.

Ever since installing SP3 if I double click a file out of the file system I get another instance of CD open with the correct page size but no graphics in it. I then have to close that CD session and drag the file into the already open instance of CD... no biggie but annoying as I double click out of the file explorer all the time.

I'm having trouble with the Revit ribbon not giving me the normal commands. For example, I'm trying to place a water closet family and the modify ribbon is giving me "Import Instance" instead of placement options (as in placing on a face) like it did just a couple days ago. I was placing these water closets in this same model just a few days ago and it was working fine. I've imported a few DWG files since then and now I'm getting this behavior. how do I undo it?

I'm not talking about simply making a layer folder with various elements grouped inside. What I'm trying to do is create different screen instances of a website using a feaure that turns on specific layers, allowing me to save that "layer visible" combination. I did this a few years ago and now cannot remember how it was done. To give an example:
I have a layer folder called "main navigation" in my Photoshop file. This main navigation folder has tons of sublayer elements that include the menu itself, hover states, drop down states, etc. I have another layer folder that contains elements for a specific web page.
What I used to do was this: I could turn on one of the specific web page folders, then turn on the active state element in my Main Navigation folder. So now the page looks as if it would for that specific screen instance. At this point, I was able to create a "Layer Group" that saved this specific set of layers that were turned on (visible), and name it.
Does this feature still exist in Photoshop? I can't seem to find it anywhere, or find any documentation on how to implement it.
