When you have complex graphics coming from a CAD output the first step you might want to do is to reduce its size. Plant Simulation offers an integrated bundle of algorithms especially designed to help you with this task.
Select the new object using the right mouse key to open the context menu.
The dialog will present a set of tools to reduce the graphic size. You can either use only one function e.g. prune tiny graphics if your object contains plenty of small parts, or the visibility filter, that eliminates the parts that you can’t see anyway because they are hidden within the object or you can accept the result of one optimization algorithm and use the next one on top of it.
In the case of the tractor example the results are the following:
result in %
Using “Export Scene” > Export Graphic enables you to save the result in a new jt file. For a complex machine design the jt file size was reduced from 4GByte to 800kByte.
This feature is very interesting. I have a very large .wrl (4go) of an assembly line, and i need to optimize the graphics in order to help my cpu
But, testing all the parameters take a long time for a such file (about 15 to 30min for 1 test...).
Can you advise me some settings to reduce to the maximum? (or maybe a table with some settings related to graphics losses...)
Thanx in advance !
There is no general "best optimization" - if there were one, you probably would already have a button that offers you to perform it.
However, there are some best practises:
Thanks a lot for the quick response ! I'll try that. The order seems to be very important in order to have effective results.
Without this "procedure", i've tried a lot of successive optimization, with very different results...
Many thanks !
Can an optimized model be exported to be used somwere else and how huge input model can be? The thing is, that instead of CAD models I have to use 3d scans. They are made with Artec Studio, which has optimisation in it, but still outputs huge files. I'd like to know if I can optimize the scans in PLM to the minimum size possibe.
This is a bit difficult to answer.
In general, you can export graphics from Plant Simulation and so, since you can optimize them in the application, you can technically use it as an optimization tool for Jt graphics.
There are two, unfortunately somewhat fuzzy, limitations:
Long story short, I'd like to encourage you to try the optimizations in Plant Simulation but I cannot guarantee that a particular other application will work with them as expected.
I can put one limitation from Plant Simulation side here:
Since Plant Simulation only needs the faceted data of Jt file, we do not keep any addition data that might be stored in a Jt file - and so we cannot export them either. I your target application depends on them, this cannot work. But typically, since Jt's standard data are the faceted data, this has been rarely ever an issue.
I have a similar question.
Currently we get many 3d equipment files from suppliers, which are usually big (at least 300 MB, reaching a couple of GB).
We are trying some 3D optimization tools, and Plant Simulaion's is very eficient/simple.
For Plant Simulation applications, that is more than enogh. But we were wondering if it would be possible to export an optimized JT from Plant Simulation and then re-import it to Line Designer or Teamcenter?
I have attached a picture of the error message.
I you want to export a Jt from Plant Simulation to be used in CAD tools such as NX, please select the "Optimize for CAD" option in the file dialog. That way, the Jt will be built in a way that is better suited for these applications (available from version 14.0.3 onward).
