[下载]：提供两个本人认为比较好的扩展小程序

风过花零

Infosnap和Quicksnap这是两个与捕捉方式相关的.

注意这两个程序全是适用于J7的,在V8下不能正常运行.设置很简单,大家可以先装载一下看看,如感兴趣或有什么疑问可以跟贴,我会稍作一些解释的.


如果大家想让它们自动随MS一起加载,请将之拷至
E:\V7\Program\MicroStation\mdlsys\required目录下

希望对大家有点帮助.

PURPOSE:
        InfoSnap is a transparent, background utility that gives you the whole
        new way to see all the information about the element where your
        Tentative-Point go to.

        It works regardless of whether you work in 2D or 3D.
       
        The DGN element information is gathered and displayed at cursor
        position, in contrast to standard MicroStation GUI that scatters bits
        and pieces of information all over the place.

        And with InfoSnatch you can use this information in your next action.
        You can make a new element same length, direction, level or color.
        Or if the element resides in a reference file, you can make that file
        the active one for edit.  
        All with only two key-strokes: down-arrow + ins.

        You should see your productivity raising right away.

------------------------------------------------------------------------------
INSTALLATION:       
        Unzip and copy INFOSNAP.MA to your \USTATION\MDLAPPS directory.
        Start MicroStation and go to:
                Workspace->Configuration->Design_Applications

        Locate INFOSNAP in the "Available Applications" list and add it to
        "Applications To Load" list.

        Exit the Workspace Configuration with the Save when prompted.
        Open any DGN file and InfoSnap will pop up.
        That's it.

        Now, snap (Tentative Point) to anything. Voila!

NETWORK INSTALLATION:       
        Define MicroStation environment variable INFOSNAP_SETTINGS pointing
        to the directory where the local settings should be stored on local
        machine(s). Give the path only, do not specify the file name.
        Settings file (INFOSNAP.DAT) will be created whenever you push
        "Save"-button in main InfoSnap Settings dialog box.

        Example:  
                Workspace->Configuration->New...
                Variable: INFOSNAP_SETTINGS
                New Value: $(MS_SETTINGSDIR)
       
FINE-TUNING:
        The Setup Dialog box can be recalled with key-in: INFOSNAP SETTINGS.
        Press "Settings"-button to open main Settings dialog box.
        Once there, create your favorite selection of what you want to be
        displayed (and how) when snapping with Tentative Points. Make your
        choice permanent by pressing the "Save"-button.

        Note, that unless you save settings at least once, InfoSnap will
        warn you and use the default values.

        The keyboard-way to change settings is through command key-ins:

        Key-in                                      Purpose

        Note: all [ON|OFF] type key-ins work as toggles when issued without
              ON or OFF modifier.


ADVANCED FINE-TUNING:
        Some graphic drivers report incorrect origin of the screen to InfoSnap
        in dual-screen Windows setup, causing the pop-up banner being shifted
        abnormally (ideally, it should open at very close proximity of cursor).
        
        Now you can compensate for this error:

        There are two (optional) environment variables controlling the screen
        offset where the balloon-text banner shows up relative to current
        cursor position. Values are given in pixels (default is 0).

        INFOSNAP_SHIFTH  controls the horisontal shift
        INFOSNAP_SHIFTV  controls the vertical shift

        Example:
                We need to move the banner 50 pixels to the left:

                Workspace->Configuration->New...
                Variable:  INFOSNAP_SHIFTH
                New Value: -50

        Close current design file (i.e. restart InfoSnap).


VERY ADVANCED FINE-TUNING:  (for third-party MDL developers ONLY!)
                            --------------------------------------

        If your MDL program is remapping MicroStation's cursor position it will
        surely create undesired side-effects for both InfoSnap and other MDL
        applications as well.
       
        However InfoSnap gives you at least a way to synchronize herself with
        such brute-force changes:

        Cook book:

        *** on entry to your application (main):
        - mdlSystem_defineCfgVar ( "INFOSNAP_SHIFT_EXTERNAL", "DYNAMIC", CFGVAR_LEVEL_USER );

                *** during the time your app is affecting cursor position:
                - compute the cursor position shift after your changes (x,y offsets in pixels)
                - redefine values of INFOSNAP_SHIFTV and INFOSNAP_SHIFTH as they change:
                - mdlSystem_defineCfgVar ( "INFOSNAP_SHIFTH", newXdelta, CFGVAR_LEVEL_USER );
                - mdlSystem_defineCfgVar ( "INFOSNAP_SHIFTV", newYdelta, CFGVAR_LEVEL_USER );

        *** on exit from your application (unload hook):
        - mdlSystem_deleteCfgVar ( "INFOSNAP_SHIFT_EXTERNAL" );

        InfoSnap will check existence of INFOSNAP_SHIFT_EXTERNAL each time it
        reads its own settings.

        Tip: if any of INFOSNAP_SHIFTV or INFOSNAP_SHIFTH were already defined,
        it would be smart to preserve and restore their initial values as a
        courtessy for the user.

KNOWN PROBLEMS:
        1.
        MicroStation can have (at most) two application windows open.
        InfoSnap won't work when one of those application windows is minimized.

        2.
        InfoSnap does not cooperate very well with EagleEye. Popup can show up
        biased to EagleEye's own popup. I.e. it is affected by cursor-position
        remapping done by EagleEye. It may, or may not be addressed in future.
        For more information see Q&A section below and the section above.

------------------------------------------------------------------------------
YES-Dept.:
        Yes, it really is the FREE stuff
        Yes, InfoSnap was available for DOS and Alpha NT as well
        Yes, we love to hear your feedback (comp.cad.microstation)
        Yes, it is a taste of MDL-stuff we can create for you (commercially!)
        Yes, there is more to it -- look at InfoGlider companion program!

NO-Dept.:
        No, you don't need to be on SELECT/CSP to get this stuff
        No, MDL source files are not part of this offering. Sorry...
        No, we will not continue support for earlier MicroStation than v7.0

FINAL WORD:       
        I am very interested in constructive feedback from you!

        Preferably on USENET (comp.cad.microstation) as I don't have time
        to do custom jobs for free, however if it will be apparent that the
        proposed change (or addition) gain the whole MicroStation community
        (i.e. those who use InfoSnap), I will make it at no charge whatsoever.

QUESTIONS? I BET:

Q: I can't see a thing. What is wrong?
        A: If you have other view background color than black, adjust MicroStation's
           Pointer Color (InfoGlider uses the same color): Settings->DesignFile->Color

        Q: The popup banner disappears, sometimes right away, sometimes after
           a while. Can I make it stick?
        A: The banner will disappear when you:
           - press RESET mouse-button
           - run-over the banner with cursor
           - touch the view border with the cursor
           This is by design, in order to uncover geometry beneath the banner
           (frankly, is there the less obtrusive way to do it without a click?)

        Q: The popup banner goes away immediately. What can I do about it?
        A: There is a possible timing-conflict with another application.
           Defining a 'Delay' period (as a fraction of a second) should fix it.

        Q: The popup banner shows up far away from cursor!
        A: See ADVANCED FINE-TUNING section above.

        Q: When I snap to cell components, the popup banner sometimes don't
           show up. MicroStation is highlighting different cell components.
        A: Enable 'Exact elem. target', which enables InfoSnap to see inside
           the cell (or any complex element for that matter).

        Q: *** What is Settings-Snatcher?
        A: When you set InfoSnap balloon-format to 'TABLE', you may pick
           almost anyone of displayed parameters and make it active!

           Just use UP and DOWN arrow keys (or TAB) to select the item inside
           the balloon, and press INSERT key to snatch its setting and make it
           active.
          
           If you select "Diam=", "Length=" or "Radius=", the value will
           be sent to AccuDraw as the Smart-Locked Distance Delta.

           Note, that you have to have any placement tool active to get this
           working.

           If you select "RF" (Reference File), it will be made the active file.
           If you want go back, press HOME-key.

           There is more:
           If you like to apply ALL settings at once (i.e. make them active),
           just press INSERT key without making the item selection first.
           This one works for all balloon-formats.
            
        Q: *** What is Message-Snatcher?
        A: When you are using MicroStation standard measure-tools, the numeric
           output  is displayed usually in lower right corner of screen(s).

           If you think that by far more logical place would be in close
           proximity of cursor, activate Message Snatcher and it will display
           those messages near by the cursor.
          
           In a case you need to recall the last message:

           If you have defined any key as WakeUp-Key, press it.
           (On MicroStation 95 you need to _move_ your cursor slightly while
           key is pressed. This is not necessary on MicroStation SE)  

           MicroStation's textual output will pop up again near by the cursor!
           If you have defined mouse button for this purpose, press it when
           no element is highlighted (selected).

        Q: Why Message Snatcher is colliding with Element Info balloon?
        A: You need to define the precedence. Use radio-buttons:
             'Snatcher'-button gives highest priority to Message Snatcher,
             'Elm. Info'-button gives highest priority to InfoSnap Element Info,
             'Both'-button gives the ability to see both.
           Note that 'Both'-setting requires long enough 'Delay' setting.

        Q: Where are the InfoSnap settings stored?
        A: Stand-alone installation: The settings are stored in the application
           itself. It gives a one file less to worry about.
           Network installation: The settings are stored in the INFOSNAP.DAT
           in directory defined by INFOSNAP_SETTINGS environment variable.

        Q: Where is the angular measure taken?
        A: Look carefully close to the mouse cursor (the little one, not the
           large cross-hair snap cursor).
           You'll se a little dot appear. This is the point of measure.
           (It will go away on RESET)

        Q: What is 'User Units = Master/[1.0]' radio-button?
        A: Length (or perimeter) and Area can be reported in Master Units,
           Working Units or User Units (a Master Unit / Divisor ).
           It is handy when geometry was drawn in Imperial units and you want
           InfoSnap to report in Metric units (or vice versa). Just supply a
           suitable divisor to make conversion happen.

        Q: I can see intermitently a '+' prefixes at different places. Why?
        A: The '+' character indicates that immediately following information
           is being temporarily overriden by another setting.
           For example 'CO=3' means element color 3, and '+CO=5' means that
               element color is currently overriden by Level Symbology Attribute
               (in selected view) specifying color 5.  And so forth...

        Q: Is InfoSnap compatible with: ..........  < fill the blanks ;-) >
        A: InfoSnap was tested with MicroStation Foundation products ONLY.
           It has been found to cooperate nicely with a number of third-party
           applications as well.

           However, as a freeware it is (non-profit, public domain program),
           there are no plans whatsoever to modify InfoSnap in order to fit
           into any _commercial_ application environment.
          
           Only other _freeware_ products can be reviewed for compatibility
