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.
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 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?
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?
I got a simple question about the creation of copies of an object. Is it possible to have the objects in the mirroring of an object change with the object used as reference for mirroring?
If there is no function to do this directly is there a way to do it via Ilogics to update the mirrored objects? If possible even by deleting and creating a new the mirroring yet not manually but by i logic?

I derived in a part and I am trying to use a sketch from it in my new part.
I am trying to revolve my sketch and when I do I get this error.
I am using a English version, and I cant read chinese at all. Design doctor shows no errors, but this will not revolve. Tried Extruding and get the same error. When I try to revolve, it shows a preview of my part correctly, but when I click apply in the revolve dialog, that is when I get this error.

I wondered if there is a way of changing view reference from one object to another.
Example.
I have two similar models but drawing done for one.
I could save it as with a different name and replace in all the views referenciing from old model to new one.
Possible?
Using C3d 2013. I am looking for a way to place the deflection angle of the PI of an Alignment in the label of a structure part that references said alignment. But PIs aren't an option when I select Reference Text type. Common sense tells me it would be under Alignments, but none of the PI data is an option of the Contents' Text Component Editor. I couldn't find it under any of the other Reference Text types either. I can pull the station value from the referenced alignment, is there a way to get it to tell me the deflection angle at the PI it sits on? Or even the difference in the instantaneous direction just before and just after the part?
I know listing the deflection angle of a PI is possible, as I have seen it in several examples of labeling alignments. I just want to place it in the label of other objects.who can tell me how to display LT (to represent left) and RT (to represent right) when the deflection is positive or negative respectively.
How can i do referential scaling, like scaling an object with reference to another? see the video. open in new tab or click on it too see the video.
View 12 Replies View RelatedWhen we select an art object in Illustrator we can get the (x,y) position and the size of the selected object in the control bar.
At the left of the x value, there is something called reference point. We have nine possible choices. (bottom-left, bottom, bottom-right, left, centre, right, top-left, top, top-right). Its name seems to be the reference point (from the tooltip).
Is it possible to retrieve the current choice of the user ?

I'm working on a large infrastructure project with numerous of drawings. On quite a few layout drawings I need to have the same base set of references, however I need to change the layer settings (colors, lineweight etc.). This cannot be done in the base reference itself as it is used by others. As the layouts I work with includes other references as well, it is time consuming to filter and change layer settings on each base reference.
My concept is to have a master reference file to manage all layer settings and add/remove base references. When the master reference is referenced into the layout, all layer settings on the base references should stay as set in the master reference. In this way I can easily control all base references with one file and make sure all changes will be the same for all the layouts.

I am getting this error in my production drawings.
My setup is as follows:
- EG.dwg has my existing surface in it. I create a data reference to use it in other drawings.
- Level One.dwg has the EG surface data referenced in, and I use this to create alignments, profiles, and finish surface. All of these are turned in to data references.
- Storm Sanitary.dwg has my pipe designs. I data reference in the two surfaces, profiles, and alignments, and create pipe networks. I create references for these networks.
- Plan Profile.dwg is the production sheet I'm getting this error from. Every one of my civil objects is data referenced in to this drawing. Everything is inserted correctly, the pipes show correct FG surface elevations for their rims, etc.
BUT when I open this drawing, I get this error. I assume it's because my FG surface is not directly in the storm sanitary.dwg.
How do I get rid of this error, without combining drawings, or promoting the surface to one or more drawings? Isn't this exactly what data references is made for?

View 2 Replies View RelatedI'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'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.
