Reducing the file-size of a large dwg-file

Genius

Hello community,

 

I am looking for a way to reduce the size of a large dwg-file, which I use as background in my simulation model. Is there a way to reduce/ optimize the file-size with Plant Simulation?  For viewing the dwg-file, I am using Autodesk Trueview. 

 

Thanks in advance! 

 

With best regards,

NiRoe

if you are talking about a 2D dwg,

 

which I suppose you are, then you cannot reduce the

 

size ( through Plant Simulation). The reduction of the

 

triangulation of 3d geometries is possible through Plant Simulation.

 

I'm not sure, if the dwg data, used as background, isn't converted into a bitmap anyway.

 

Then the dwg filesize shouldn't have a big impact.

Yes, I am talking about 2D dwg.

I am not sure if the dwg file is converted into a bitmap. There is a significant performance increase, if I do not use a dwg as background.

I do not know if this matters, but the dwg file has a size of 13 MB

dwg files are indeed converted into bitmaps when they are imported.

@ there is a big performance increase, If I do not use a dwg background.

What kind of performance increase are you talking about ?

Hello simulator,

the simulation is running faster, if I do not use a dwg file as background. If I run a simulation with the dwg-file, the simulation takes very long, even if I try the setting for "very fast simulation"

Just to be clear, you are using Plant Simulation in 2D mode, right? You are not displaying a 2D (i.e. flat) dwg in a 3D window of Plant Simulation.

 

Is the simulation still slow when you close the frame window?

Which version of Plant Simulation are you using?

Yes, I am using Plant Simulation only in 2D mode. And I am using Plant Sim 13

The simulation is fast again, if I close the frame window.

What I need to mention at this point: I implemented one frame in another frame. Both frames use dwg-files as background. If I close the top frame in the hierarchic structure, the simulation is faster again. If I delete the background, the simulation is faster again...
