AutoCad 2D :: What Exactly Is Upper And Lower Bound
Aug 24, 2011
When i bring a model in layout using chspace and ls it for its co-ordinates, it gives me upper bound and lower bound coordinates.What exactly is upper bound and lower bound coordinates?
As you can see on the attached image, I've got a Monitor on a movable arm that is fixed at the opposite end. I am having trouble rigging a section of the arm (shown as 'arm 2'). The problem I'm having is that the handle moves the arm around, but in order to move the arm up/down the two sections of arm 2 pivots in 4 places.
I have a bone structure through the upper section, which works. But when I try to put a bone through the lower section as well, the upper link breaks or the handle wont rotate properly.
So effectively I am trying to split the rig like this -=-.
Any clue how I can do this, or is there a better way of doing this?

Upon binding my dwgs to send to clients, sometimes I run across a serious problem. My xref'ed site plans disappear but my xref manager still lists it as attached, the layer manager still has every xrefed layer, and all other xrefs in the dwg will bind perfectly.
I have broken down all complex objects, purged, audited, cleaned up any excess scales, and even created new fresh dwgs for the xref and the drawing in question; all actions have ended in failure. I have even searched the AutoDesk forums for a solution and have found nothing substantial.
Solution: #1 Use RECOVERALL command on .dwg file that the xrefs disappear from. It will remove all proxy objects and excess scales in the file that is causing it to disappear in the first place.
#2 WBLOCK out the dwg file and any xrefs that are disappearing and insert them into new "clean" .dwg files. Must be done to all files.
I'm a document controller that is trying to ID the situation with 2600 drawings. Some files are so large - 250,000kb, they won't open. They have bound xref's in them. We want to ask the contractor to unbind them and attach them as normal xref's. I need to view if a drawing has bound xref's. I just want to see them as BLOCKS which I now understand they are. How do I do view the blocks that were once xref's?
I have been attempting to pass a string array contained in a variant to the AutoCAD method AcadPlot.SetLayoutsToPlot. I am using late binding without a Interop assembly because we have several versions of AutoCAD in this company and I would like to support all of them from the same code base.The method wants a variant that contains a string array passed byref. The Microsoft documentation on COM interop from VB.NET makes it sound like the compiler will marshal it correctly by default, but it always throws a COMException (Exception from HRESULT: 0x80070057 (E_INVALIDARG)).
The stack trace shows it is trying to anyway:
StackTrace: at Microsoft.VisualBasic.CompilerServices.LateBinding.InternalLateCall(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack, Boolean IgnoreReturn) at Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateCall(Object Instance, Type Type, String MemberName, Object[] Arguments, String[] ArgumentNames, Type[] TypeArguments, Boolean[] CopyBack, Boolean IgnoreReturn)
But no matter how I code it I cannot get this variant array passed to AutoCAD.I have tried:
Imports System.Runtime.InteropServices ' VB default marshalling Dim layoutarr = New Object() {"Layout1"} doc.Plot.SetLayoutsToPlot(layoutarr) ' using a VariantWrapper Dim layoutarr = New Object() {"Layout1"} Dim wrapper As New System.Runtime.InteropServices.VariantWrapper(layoutarr) doc.Plot.SetLayoutsToPlot(wrapper) [code]...
As intensively as AutoCAD ActiveX uses variant arrays, I know this problem is going to come up again and again for me as I try to migrate code over to .NET.
In Photoshop CS6, the moment you select the Crop Tool, a "cropping bounding box" appears instantly over the image. This didn't happen in CS5. In CS5 I would be able to click and start dragging the Crop Tool 'outside' the image and then drag into it so that my "cropping bounding box" (don't know what to call it) would snap to the edges of the image.
In CS6, since this box is automatically there already over the entire image, clicking outside the image invokes some unwanted rotation action.
I have a computer where all text entered in AutoCAD text/mtext comes out in uppercase. Pressing the shift key while entering the text has no effect. The CAD-Girl involved has admitted to sniffing around in Express Tools System Variables and changing a few, but she cannot remember any more which ones she changed.
I am currently working on a culvert drawing, using two view ports for my plan and profile sheet. As you can see below in my attachment, the UCS icon in the upper viewport is distorted, I do not how this occurred nor do I know how to correct it.
I am writing various text insertion lisp routines. I want the computer to default to UPPERCASE before the user enters any text to ensure the text is added to the drawing as UPPERCASE text at all times.
I am wanting to display previews (pngs) of the ai files in the plugin that match search criteria on a button. As the user scrolls through the results, change the button picture to be the png for that ai file. I tested it with a default image in case the image doesn't exist. The test image is cropped to the size of the button.
The pngs are necessarily 600x600 pix. (For other applications). I want to resize them for display on the button.
I am creating an upper cabinet which has a fixed height but you can select different widths. What our firm does is also list the size of the cabinet. What I would like to do is make this font some sort of preset attribute and control it with the visibility states. I also want to control the font height by the scale of the drawing. my question is I if its possible and how? I've attached what I have thus far. The attribute is in teh top right corner and is justified as top right. The only way I can get this to work is if I manually adjust the font after its inserted into the drawing.
The minimize, restore down, & close icons keep disappearing from the upper right hand corner on my current drawing file in 2013 LT. They will reappear once I re-zoom the drawing. Is there any way to keep these icons on the screen at all times?
I am having problems printing from AC 2013. In one drawing I can print 42" x 380" with no problem but then I open a new drawing and try printing 42" x 315" AC doesn't send it to the printer. In the 42" x 315" drawing if I set my paper lower than 300" it prints fine.
We are having this problem with all 8 of our AutoCAD stations.
If we go to Tools / Options / Open and Save / Thumbnail Preview Settings, in the "Sheets and Views" panel, the "Performance-Accuracy Slider" is set all the way to the right, which the Information Panel lists as "Update thumbnails when saving drawing".
This makes our SAVEs very long.
We can slide it to the middle and our SAVEs become very quick.
But we have to remember to change it for EACH drawing we open.
I forgot on the last one and has been saving for half-an-hour so far.
Is there any way to keep the slider in the middle for each time we open?
I don't know why when I make an automatic intersection the curb assembly is placed on a lower elevation respect to the main and second roads in all quadrants.
