1.      Overview

        This disk contains all components of the add-on 
        application ELSAview 3D for AutoCAD R14.01,
                                    Mechanical Desktop 2.0, 
                                    Mechanical Desktop 3.0        
                                    and ADT 1.0.

        Earlier versions of this application are known by the
        name POWERview 3D. This documentation uses the new name 
        even if referring to the earlier versions.

        Supported platforms are Windows NT NT 4.0.

        For detailed information please see the online-help. This
        includes a section with release notes.

------------------------------------------------------------------

2.      Directory Contents

        The program's setup directory contains the following 
        files:

        README.TXT      this file
        LIESMICH.TXT    German version of this file
        Ev3D.hlp        ELSAview 3D help file in English
        Ev3D_de.hlp     ELSAview 3D help file in German
        SETUP.EXE       Installation program for Windows
        (all others)    files that will be installed
    

------------------------------------------------------------------

3.      Installation / Deinstallation

        For installation start SETUP.EXE by the menu item File/Run 
        in the Program Manager or double click SETUP.EXE in the 
        File Manager or Windows Explorer.

        It is possible to run SETUP.EXE in a silent mode to avoid
        user input. See the ELSAview help for more information
        about this mode.

        The installation and the deinstallation can change some 
        files of the original AutoCAD installation. These files 
        are "acad.rx" and "acad.pgp" (in the support-directory).
        These files are backed up to "acad_rx.bak" and 
        "acad_pgp.bak".

------------------------------------------------------------------

4.      Notes

        If you have used a beta version of ELSAview 3D before, do 
        not use data created with that (*.iv, *vrml...) version. 
        Due to special changes, we can not guarantee that it will 
        work with this actual release.

        If you got this file set in compressed format, make sure 
        to expand it retaining the subdirectory structure. Use the 
        option "-d" for PKUNZIP or an equivalent option, if you 
        use another packer.

------------------------------------------------------------------

5.      Support

        Please report problems with a detailed description, a
        description of your system and - if applicable - with a 
        sample data set to our ELSA Support.
        In the ELSAview help you can see how to reach the support.

------------------------------------------------------------------

6.      Using Accelerator Keys
        
        NOTE: You should have experience with AutoCAD menu files,
              otherwise consult your AutoCAD documentation.

        To make the switching between AutoCAD and ELSAview 3D more 
        comfortable you can define an accelerator key for AutoCAD.


6.1     AutoCAD R14

        Perform the following steps:

        (0) Close all AutoCAD applications

        (1) Make a backup of the following files in 
            <ACAD home>\win\support or <ACAD home>\support:

              - acad.mnc   acadfull.mnc
              - acad.mns   acadfull.mns
              - acad.mnr   acadfull.mnr
              - acad.mnu   acadfull.mnu

        (2) Delete the following files in the path 
            <ACAD home>\win\support or <ACAD home>\support:

              - acad.mnc   acadfull.mnc
              - acad.mns   acadfull.mns
              - acad.mnr   acadfull.mnr

        (3) Open acad.mnu with Notepad or a similar editor.

        (4) Search for the section : ***ACCELERATORS

        (5) Append the following line to the end of this section:
      
               ["F3"]^C^C_pvfront
            This command establishes an accelerator on the 
            command key F3 so you will be able to switch to the 
            viewer by simly pressing F3.

        (6) Save the file.

        (7) Repeat steps 3 through 6 for acadfull.mnu.

        (8) Start AutoCAD.


6.2     Conventions for using accelerator keys

        You can combine several keys by using +, e.g.:
        [SHIFT+"F3"]

        control keys         CONTROL SHIFT
        F1-F12               "F1' "F2" ... (except F10)
        cursor keys          "UP" "DOWN" "LEFT" "RIGHT" 
        position keys        "HOME" "END"
        numeric keypad       "NUMPAD0" "NUMPAD1" ...
        other keys           "INS" "DEL" "ESC"

        Please do not use keys that are used by the system, e.g. 
        "F1" for help.
       
------------------------------------------------------------------
7.      Caveats / Known Problems

        When used with Mechanical desktop the ELSAview 3D toolbox
        may be unloaded when you load a new drawing.
        See section 6 for a workaround.

        If you have used an earlier version of ELSAview 3D before,
        please delete the following registry entry to avoid 
        crashes:
             HKEY_CURRENT_USER\Software\ELSA\POWERview3D

        If you use MS Netmeeting be sure to use the latest NT 
        drivers (v5.26.00.227 or later) for your graphics board. 
        Older drivers could prevent ELSAview 3D to get a valid 
        license to run.
        
        Loading drawings generated with versions before AutoCAD 
        R14 into R14 could lead to problems when editing light 
        sources. Autodesk has improved the light sources in 
        AutoCAD R14. These changes are not compatible. If the 
        viewer edits an old light source AutoCAD crashs.
        To avoid this problem perform the following steps for 
        older drawings:
         1) load drawing into AutoCAD R14
         2) call the light dialog (AutoCAD!)
         3) select one light source
         4) click on the 'modify' button
         5) click on 'ok'
         6) repeat steps 3 - 5 for every light source 
         7) save drawing
        Now the light sources have the valid format ELSAview 3D is
        able to work with.
        
 	There are some drawings in VRML2 format which can not get 
	saved in VRML format again.
        
        Saving a drawing to a *.wrl file can lead to color errors
        in the saved file. Only entities on layer 0 with color 
        by layer in blocks show this problem.   

        Rendering to the Mechanical Desktop v2.x viewport will
        only work when the ARx module of ELSAview 3D was loaded
        by acad.rx (as is default in Setup). When you load the
        ARx module manually only rendering to a separate window
        will be available.
        The problems occurs in connection of AccelVIEW 3D. You
        can avoid these problems completly by renaming the file
        "accelvw.arx" for examble in "accelvw_1.arx". You can 
        find the file in the AutoCAD directory. 

        To avoid problems with ELSAview 3D we recommend to 
        update your AutoCAD installation to R14.01.

        To avoid problems using ELSAview 3D and POWERdraft
        together rendering to AutoCAD's viewport, you should
        use the latest version of POWERdraft (V14.02.06 or 
        later)

        Toggling between Assembly and Scene View can lead to 
        some rendering artefacts. To avoid this problem it is 
        recommended to use the EVALL command after toggling.

        When using ELSAview 3D together with ACAD-BAU the 
        startup procedure will not execute a command needed
        for a correct start of ELSAview 3D. You have to call 
        this command manually by entering "evreinit" after 
        ACAD-BAU has started.

        Sometimes there is a hang up of AutoCAD when rendering
        with ELSAview 3D in AutoCAD's viewport. This can occur
        with very small drawings (containing only few objects).
        If the user uses the interactive mode (EVI) AutoCAD will 
        hang when the user leaves the mode with 'accept'.
