.NET
Pro or higher
The BricsCAD .NET API exposes BricsCAD functionality for use by
managed code built on the .NET Common Language Runtime (CLR)
platform.
Runtime
With BricsCAD V21, the supported .NET framework version is 4.5.1 (CLR version 4).
The .NET 4.5.1 framework is highly compatible with .NET Framework 4.
Existing modules compiled for older BricsCAD versions should work in V21 unless version-dependent P/invoke signatures were used to access unmanaged API functions.
Compiler version
For new development on V21,
developers must use Visual Studio 2017 or later. Managed modules
compiled with .NET 4 for older BricsCAD versions will continue to
run on V21 but Visual Studio 2010 and older versions of VS will not
recognize the current BrxMgd TD_Mgd modules because they are based
on .NET 4.5.1.
For .NET based development it is
sufficient to use the free Visual Studio Community
Edition.
.NET project setup in Visual
Studio
Create a class library using the class
library wizard under your preferred .NET language. Reference the two required DLLs (BrxMgd.dll and TD_Mgd.dll). Reference the optional BREP API (TD_MgdBrep.dll) and/or 2d constraints API (TD_MgdDbConstraints.dll) if needed. These DLLs are located
in your BricsCAD installation folder.
Important note: when referencing
these DLLs, it's important to set the 'Copy
Local' property to False.
Note: importing the BricsCAD and
Teigha COM type libraries requires TlbImp without the /strictref option!
Sample projects can be found in
the BricsCAD install folder, subfolder
\API\dotNet.
Bricscad.Internal
Since V18, the
Bricscad.Internal namespace has been added, with plans to add
undocumented functions upon request.
Changes in V21
BRX20.DLL has been
updated as BRX21.DLL, P/Invoke signatures depending on this file
will need to be updated accordingly.
Code
compatibility
It's generally
possible to use the same source code to build assemblies targeting
both BricsCAD and AutoCAD. A common technique for resolving
differences in namespaces is to use short namespace aliases that
are different depending on the target
application:
