From DocR19

This service pack is a collection of new features and updates that fix issues reported against the ACIS R19 release and incorporates all of the ACIS R19 content.

Important: The service pack is standalone and must be installed into a directory that does NOT contain prior releases.

This service pack is not a required upgrade; however, if you are currently running ACIS R19, we encourage you to download this service pack to ensure that you are running the most current, up-to-date version of ACIS.

Note: This ACIS service pack should be used with the same service pack level of InterOp.

Release Notes R19 SP1

Enhancements

Kernel

• Restore

The ACIS restore process has been enhanced to restore models containing non-native geometry. All model faces that reference non-native geometry either directly or through underlying edges are automatically removed from the models. This allows the restore process to be successful, albeit by creating possibly incomplete models, in situations where it would normally have failed.

Resolved Issues

For any issues you have submitted, log into the Downloads area at the Spatial Web site to check their status.

After entering Y to confirm the location of the installation directory, the installation program completes the installation process.

Directory Structure

The directory structure is divided into subdirectories as detailed below:

bin directory

The bin directory contains all 3D Modeling and Visualization Product Suite executables, shared libraries, and DLLs within its subdirectories. For each platform you install, bin contains two arch subdirectories: one for the release mode architecture, and one for the debug mode architecture.

docs directory

The docs directory contains the ReadMe files.

include directory

The include directory contains 3D Modeling and Visualization Product Suite header files.

lib directory

The lib directory contains all 3D Modeling and Visualization Product Suite static archives and Windows import libraries (.lib files) within its subdirectories. For each platform you install, lib contains two arch subdirectories: one for the release mode architecture, and one for the debug mode architecture.

scm directory

The scm directory contains code for Scheme AIDE (scheme interpreter, Scheme extensions, Scheme scripts and projects for building the Scheme AIDE), and example projects and makefiles for rebuilding Scheme AIDE.

src directory

The src directory contains source code (such as examples) that is shipped with 3D Modeling and Visualization Product Suite.

redist directory

The redist directory contains Microsoft redistributable packages for those who build their application using the Microsoft Visual Studio .NET 2005 (SP1) compiler.

Digital Signatures

Spatial products on Windows Operating System with Microsoft Visual C++ 2005 compiler are digitally signed for identification purposes. Digital signatures for Spatial products have been issued by VeriSign and recipients can use this to authenticate the identity of Spatial products.

Important Notes about Building Your Application with R19

Understanding False Memory Leaks Reported in ACIS-based MFC Applications

False memory leaks are reports of leaks by memory management systems that can be proven to be erroneous. In this case Spatial specifically refers to the leak reports generated by the Microsoft debug CRT when an ACIS-based MFC application exits.

Faulty leak reports are generated when the runtime library that was loaded last exits, not when the runtime library that was loaded first exits. In other words, the faulty leaks are reported when the first runtime library exits, not when the last one exits. (This is a bug that has been acknowledged by Microsoft.) Moreover, other libraries may be unloaded after the first runtime library exits. These other libraries may free memory when they unload, which is the case with ACIS libraries. These deallocations can occur after the leak report has already been generated, in which case they are incorrectly reported as leaks.

No faulty leaks are reported when all runtime libraries are loaded before other libraries during application startup. This desirable behavior can be achieved by managing link order and by managing the types of run-times used by the application.

Libraries specified as additional dependencies in the project settings are loaded in the order specified before all other libraries. (This is referred to as "explicit linkage".) Adding the appropriate MFC runtime library to the beginning of the link dependencies should remove erroneous leaks in most cases. Additionally, you can load all libraries with the use of pragmas. This is the suggested way to link ACIS libraries into your application. (This is referred to as "implicit linkage".) From our experience, applications that link libraries implicitly are less likely to encounter faulty leak reports. Note that pragmas added to source code will, therefore, require project rebuilds.

Faulty leak reports can also occur when mixed versions of runtime libraries are loaded because of dependencies from other libraries. For example, a typical MFC application may use MFC80D.DLL and have dependencies on other libraries that use MFC80UD.DLL. The latter library may be loaded after other libraries have been loaded, specifically after ACIS libraries are loaded. This is a scenario for faulty leak reports since libraries are unloaded in reverse load order. This cannot be solved with explicit linkage because of link errors (such as multiply defined symbols) and mixed runtime issues. The best solution is to manage the types of run-times used by the application by using the same ones whenever possible.

Update Tool

In versions prior to and including R12, an Update Tool was provided with 3D Modeling and Visualization Product Suite to assist in migrating customer code to the new version. This tool primarily implemented changes in header file path references. R13 through R18 have no such changes, therefore no Update Tool has been included with these versions. If you are migrating from a version of 3D Modeling and Visualization Product Suite older than R12, contact Spatial Customer Support to obtain the appropriate version of the Update Tool.

HOOPS/ACIS Bridge Libraries

Graphics Card Information

The HOOPS 3D Application Framework supports a large number of graphics cards. However, with the large number of graphics cards and machines available today, it is possible that you may encounter a display problem when running the HOOPS-enabled applications such as the ACIS Scheme AIDE. If you are having problems, ensure you have done the following:

1. Ensure that you are running the latest version of ACIS.
2. Check the Tech Soft 3D site for updated information on your video card.
3. Contact your graphics card provider. Your graphics card provider should be able to provide information, suggestions and even updated drivers to help solve the problem.

If you are still experiencing problems, contact our Spatial Support Services department or visit the Online Support Center.

Windows Library Naming Conventions

Starting from the 3D Modeling and Visualization Product Suite R11 release, ACIS libraries on various Windows platforms are named differently so that they can be installed in a common directory. Each set of libraries has a common root name appended with a platform-specific abbreviation. The table below illustrates how the DLL and Import Libraries for SpaACIS are named on each platform.

Library Extension on AIX Platform

In order to comply with standard naming conventions for shared libraries, all libraries on the AIX platform have an ".a" rather than a ".so" extension.
