Creating MPOLYGON using VBA

Anonymous — Thu, 07 Sep 2006 05:34:20 GMT

Sorry for cross posting.
I'm using AutodeskMap 3D 2005. Is it possible to create MPOLYGON using VBA?

TIA,

Hi Roy,

I'd never heard of an MPolygon till I saw your post.

The help files for AutoCAD are fairly weak in describing the object, however
I could draw one and it appears to be a hatched closed polyline.

Searching the VBA Object model for Map and AutoCAD finds no reference to it.

You could however draw a closed polyline and apply a hatch to it. There is
sample code for doing this installed with AutoCAD.

Hi Laurie,

It's look like MPOLYGON is specific to Map. I'm not so sure about this
since I only use Map. You can find MPOLYGON in the Map's online help.
But not in the Map's nor CAD's ActiveX reference.
MPOLYGON share the same dxf group codes with hatch entities. Documented
under 'DXF Reference' in AutoCAD 2005 Developer Help.

Yes, it's looks like hatched closed polyline. Unfortunately, I could not
use this way because our client needs all polygon should use MPOLYGON type.

Actually, all I need to do is to import thousands of ESRI shp files into
dwg files with Object Data. Many of those shp files is polygon type.

I can import them using Map's Import Tool manually, and those polygons
successfully becomes mpolygons in dwg. Sadly, I can't use the tool
because I need to specify each the shp file name, OD's name, OD's fields
mapping, etc.

For that reason, I create an importing tool using Delphi and ActiveX. My
program read the shp files and draw the objects programmatically.
The tool is already done except for mpolygon. 😞
Should I use ObjectARX?

Hi Roy,

ARX depends on your programming skills. I'm have insufficient information
to advise in that area.

I hand drew one and ran the following code

Sub cccc()
Dim x As AcadEntity
Dim pt As Variant
ThisDrawing.Utility.GetEntity x, pt
End Sub

so I could examine the exposed properties and there was nothing usable
there. (I had thought of a copy and modify type process)

However, you could look at a "Sendcommand" process with VBA.

Lisp gives:
Command: (setq y (entget (car x)))
((-1 . ) (0 . "MPOLYGON") (330 .
7efbbcf8>) (5 . "2D69F") (100 . "AcDbEntity") (67 . 0) (410 . "Model") (8 .
"0") (100 . "AcDbMPolygon") (70 . 1) (10 0.0 0.0 0.0) (210 0.0 0.0 1.0) (2 .
"_SOLID") (71 . 1) (91 . 1) (92 . 2) (73 . 0) (72 . 0) (93 . 4) (10 -189.051
210.779 0.0) (10 -228.85 -250.548 0.0) (10 173.128 -230.663 0.0) (10 228.85
250.548 0.0) (76 . 1) (63 . 256) (11 606407.0 6.20326e+006 0.0) (99 . 0)
(450 .
0) (451 . 0) (460 . 0.0) (461 . 0.0) (452 . 0) (462 . 0.0) (453 . 0) (470 .
""))

This would imply a lisp solution is feasible.

MPolygon is not specific to MAP.

There is no support for it in ActiveX, that I'm aware of,
but there is support for it in the .NET API, another reason
why you need to stop listening to the crap being spewed
forth by people like AUGI's 'prez', and start learning .NET.

Don't put it off, because VBA/ActiveX has already gone
into 'maintainence mode', as this case (MPOLYGON) serves
to demonstrate.

Thanks Tony.
I'll give it a try. Do I have to upgrade my old Map 2005, first?

BTW, what crap do I have to stop listening of?

Oh, I see. Thx.
I'm quite new to Autodesk world, so I don't have any idea about AUGI before.
For the last one year I've been playing around .NET. I think I'll go for
.NET.

Good choice. The .NET API is limited in 05 but you can still use the ActiveX as a backup. I would recommend upgrading to get the benefits of the more comprehensive .NET API in 07.

It is. But only so much was wrapped in 05 and it keeps getting
better with every release. You can however wrap native ARX
functions that are not yet exposed. Do search the big boys have
posted samples.

The .NET API is not a direct wrapper for the ObjectARX API. It has been created as wrappers around the ARX components. Not much was originally exposed and there are also some flaws with the way things have been exposed.

ObectARX may also be an option for him if that's what you were implying.

I never learned ObjectARX purely because I thought c++ was beyond me. I promote use of the .NET API because it allows the use of a language you are comfortable with and is more powerful than the ActiveX API which is outdated and which the future is unclear.
