Performace Tip?

Hi Joaquin,

Please go through the Readme file or the excerpt from it given below which could help you.

Performance Hint! (TFHydrate) - Migrating  pre-V8i (legacy) projects to run with V8i Dynamic Views -

If a designer is using a pre-V8i (legacy) project in V8i or receives the following warning in the message center:

Performance Tip - View update speed will be increased by adding view accelerators to Building elements. Use tfhydrate.exe. on your legacy file(s).

run the TFHydrate utility (to upgrade the geometry within the project to increase the initial dynamic view display performance . This is a non-destructive process and should not cause issue with your file in either XM or V8i. It will result in a minor increase the file size.

This command prompt utility is typically found within C:\Program Files (x86)\Bentley\Triforma\Assemblies\TFHydrate.exe and should be initiated with the following parameters.

<Usage:> tfhydrate.exe directory\filename*.dgn  [/S subdirs]

Likewise a file can be “dehydrated” if a designer is not using dynamic views and would like to further compress the file size.

<Usage:> tfhydrate.exe directory\filename*.dgn  [/S subdirs] [/I invert = dehydrate]

What does TFHydrate do and why?

Pre-V8i legacy forms store a recipe to recreate a Parasolid body but they do not store the Parasolid body by default. The recipe must run each time the body is displayed (on first draw, when no runtime caching has been performed). This is the classic trade-off between speed and space. TFhydrate forces the form elements to store the body, sacrificing space for speed. Storing the body makes operations that need the Parasolid body (like unification) faster because they don't have to reconstitute the body (on first draw).

A project created with V8i does not need to run TFHydrate.exe. Parasolid bodies are automatically stored by default in V8i, unless that v8i file has been dehydrated by running the tfhydrate.exe with the dehydrate option.

Thanks

Pradnya,

I am getting an error on Win7 that looks like I need to run tfhydrate.exe as administrator.

Can you describe how to do this?

!!! Performance Tip !  message comes on all the time even on a V8i legacy dgn which seems a bit overdone if not highly irritating when designing.

Not true , on a BA 08110886 supplied model seed from 03/09/2009 with elements build from scratch the performance message does not appear - most probably older elements find their way into currently worked on dgn's - still it would be nice if one could turn the message off on inflicted older files as one rogue element is presumably not going to affect performance - the whole palaver of going into the utilities to run an exe. file just for that is rather tedious.

Robert - right click on the exe and select "run as administrator"

Cheers

Hi,

so far no result:Win XPsp3  BA 8.11.7.86
