Plotting a window from AutoCAD using .NET
This post extends this previous post that dealt with driving a single-sheet AutoCAD plot by adding some code to handle selection and transformation of a window to plot.
First order of business was to allow the user to select the window to plot. For this I used the classic combination of Editor.GetPoint() for the first corner) and Editor.GetCorner() for the second. All well and good, but the points returned by these functions are in UCS (User Coordinate System) coordinates. Which meant that as it stood, the code would work just fine if (and only if) the view we were using to select the window was parallell with the World Coordinate System (and no additional UCS was in place). In order to deal with the very common scenario of either a UCS being used or the current modelspace view being orbited (etc.), we need to transform the current UCS coordinates into DCS, the Display Coordinate System.
Thankfully that's pretty easy: no need for matrices or anything, we simply use another old friend, acedTrans() (the ObjectARX equivalent of the (trans) function, for you LISPers out there). There isn't a direct equivalent for this function in the managed API (that I'm aware of), so we have to use P/Invoke to call the ObjectARX function. The technique is shown in this DevNote, for those of you that have access to the ADN website:
How to call acedTrans from .NET application?
Otherwise the changes to the original code are very minor: we need to set the extents of the window to plot and then set the plot type to "window", apparently in that order. AutoCAD complained when I initially made the calls in the opposite sequence.
Here's the C# code:

Allowing selection of an AutoCAD plot device and media name using .NET
A comment came in on this previous post regarding how best to know whether a media name is valid during your plot configuration.
There are a few approaches, other than the one I chose of hardcoding the device and media names. The first is to implement a user interface of some kind which allows the user to select the device and media names. Another approach for setting the media name is to use PlotSettingsValidator.SetClosestMediaName() to choose the media name that most closely matches the paper size you desire.
Today I'll focus on the first option, although I'm only going to implement a basic, command-line user interface. It should be straightforward to extend this to implement a WinForm with comboboxes for the device and media names.
I implemented a simple function called ChooseDeviceAndMedia() which queries the current device list, allows selection from it, and then gets the media name list and allows selection from that. I chose not to worry about displaying locale-specific names, for now - I'll leave that for a future post (let me know if you're interested :-).
Here's the function integrated into the C# code from this previous post, which defines a command called MPLOT:
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;

string devname = "", medname = "";
PlotSettingsValidator psv =
PlotSettingsValidator.Current;
// Let's first select the device
StringCollection devlist =
psv.GetPlotDeviceList();
for (int i = 0; i < devlist.Count; i++)
{
ed.WriteMessage(
"\n{0} {1}",
i + 1,
devlist[i]
);
}
PromptIntegerOptions opts =
new PromptIntegerOptions(
"\nEnter number of device to select: "
);
opts.LowerLimit = 1;
opts.UpperLimit = devlist.Count;
PromptIntegerResult pir =
ed.GetInteger(opts);
if (pir.Status == PromptStatus.OK)
{
devname = devlist[pir.Value - 1];
ed.WriteMessage(
"\nSelected: {0}\n",
devname
);
// Now let's select the media
PlotSettings ps = new PlotSettings(true);
using (ps)
{
// We should refresh the lists,
// in case setting the device impacts
// the available media
psv.SetPlotConfigurationName(
ps,
devname,
null
);
psv.RefreshLists(ps);

Previewing and plotting multiple sheets in AutoCAD using .NET
This was a fun one to work on. The code in this post combines and extends upon techniques shown in two earlier posts: one showing how to plot multiple sheets and the other showing how to preview a single-sheet plot.
One of the key differences when plotting or previewing is that while plotting can directly support multiple sheets (assuming the device does so), previewing does not. The good news is that AutoCAD provides you the user interface elements to allow cycling through plots: the user is provided with "Next" and "Previous" buttons - it's then up to you to implement the appropriate logic to preview different sheets when the buttons are used.
I chose to use the same helper function for both preview and plot, even though they are a little different in nature. The reason is obvious (to me, at least) - it reduces the amount of code to debug and maintain - but it might, for some, make the code a little less easy to read. Ultimately the trick I used was to reduce the set of sheets being handled at the beginning of the function to a single sheet in the case of a preview, which allowed me to combine both approaches in a single function.
Here's the C# code:
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.PlottingServices;

using (tr)
{
// First we need to collect the layouts to
// plot/preview in tab order
SortedDictionary<int, ObjectId> layoutDict =
new SortedDictionary<int, ObjectId>();
BlockTable bt =
(BlockTable)tr.GetObject(
db.BlockTableId,
OpenMode.ForRead
);
foreach (ObjectId btrId in bt)
{
BlockTableRecord btr =
(BlockTableRecord)tr.GetObject(
btrId,
OpenMode.ForRead
);
if (btr.IsLayout &&
btr.Name.ToUpper() !=
BlockTableRecord.ModelSpace.ToUpper())
{
// The dictionary we're using will
// sort on the tab order of the layout
Layout lo =
(Layout)tr.GetObject(
btr.LayoutId,
OpenMode.ForRead
);
layoutDict.Add(lo.TabOrder,btrId);
}
}
// Let's now get the layout IDs and add them to a
// standard ObjectIdCollection
SortedDictionary<int,ObjectId>.ValueCollection vc =
layoutDict.Values;
