AutoCAD .NET :: Object Reference Not Set To Instance Of Object

Apr 8, 2012

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?

AutoCAD Inventor :: Object Reference Not Set To Instance Of Object

Oct 26, 2010

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'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.

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?

AutoCAD Inventor :: Objects In Mirroring Of Object Change With Object Used As Reference For Mirroring

Aug 6, 2012

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?

AutoCAD Inventor :: Invalid Reference To Segment Object Used

Dec 10, 2012

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.

The files are attached and here is a video of my steps. In the zip file, the -M8.ipt needs the EOF marker moved all the way to the bottom.

AutoCAD Civil 3D :: Create Reference Text To Sub Item Of An Object

Oct 18, 2012

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.

Illustrator SDK :: Art Object - Getting Reference Point

Nov 21, 2012

When 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've already started using the AutoCad 3D.

AutoCAD Civil 3D :: Object Information To Object Geometry

Mar 12, 2012

I'm making a surface out of contours. The problem is the contours have the elevation listed under object information, not geometry (the contours were brought in from a GIS file, which I do not have access to, or I would bring them in again with the elevations properly assigned, this is not an option). How can I quickly change the geometry elevation property to match the miscellaneous property?

So why when I resize the symbol instance does it break the pixel grid alignmnet and result in a blurred 1px stroke?

CorelDRAW X6 :: Update Outline Width After Resizing Object If Scale With Object Selected

Dec 14, 2013

Resizing objects is a mess in CorelDRAW X6 when objects are outlined with Scale With Object enabled to retain proportions after resizing.

None of the tools dealing with outlines (e.g. Contour or even Outline itself) continue to work properly after resizing the object.

I strongly suggest to recalculate outline property values after resizing if Scale With Object is checked. Don't just do it hidden somewhere internally in the object model by applying a temporary scaling factor. Instead actually recalculate the actual property values if Scale With Object is checked.
