Why is my dxf missing layers?

[ FlexSim 18.1.2 ]

1803-007401-78r09-2013-flexsim.dwgI am trying to import a CAD of a conveyance system. dwg wont import anything. jpg is too blurry. and dxf will import but its missing a ton of layers and its very hard to see. ive tried other tricks ive found on here for importing CAD but nothing seems to make a difference.

I have imported the file as a Background in FlexSim. It looks like it is 3D Data. I use the Black Color Scheme, then the light gray lines are getting better visual.

In Meter units I can move the main lines with these values to the Workspace Level.

The values in FlexSim with inch unit works too.

I did finally figure out the color scheme, which made it much more visible. When i try and open your fsm it tells me the tree file format is not compatible. i am on flexsim 18.1.1

File format FlexSim 18.0.8. This can you open now!

I tried both models in both versions (i just downloaded 2019) and i cant see the background in the tool box or on the floor. But regardless, i can get a similar model to yours using the scaling tricks you show, but it is still missing some layers. attached is the full dxf i would like to see. so we've solved the scaling and color issues, but im still missing layers. capture.jpg

What CAD software and version are you using?

AutoCAD 2015

Hi @Dillan J,

You might try converting your dxf file to dwg. Our dwg importer is more compatible with more features and formats, and will probably import into your FlexSim model without trouble.

Most CAD programs will let you Save As or Export to the dwg format. Let us know if that fixes the issue for you.

@Ben Wilson i have tried DWG files and they wont import anything. The background wizard doesnt list any of the layers and absoluetly nothing shows on the background. My DXF files were made from a DWG.

Hi @Dillan J,

Would you be able attach the original dwg for us to test?

If you can, I would suggest exporting your drawing as a dwg, FlexSim has some issues with dxf files.

I tried DWG. nothing would import. My DXF file was created from a DWG.

Hi @Dillan J,

I was able to import your .dwg file into a model. I had to be patient as it took a while to load (around 10 minutes, I just got other things done), but once in, it works fine. You have to be patient and let FlexSim work on importing it, even though FlexSim is totally unresponsive during that time.

One reason that it takes a long time to load is the 3D objects that are included in the .dwg. I'm guessing they have an extremely high polygon count, and thus slow down the importing and drawing of the layout. I have highlighted them with red boxes in the screenshot above.

If you open the .dwg file in your CAD software and remove those 3D objects - the orange machines, red spirals, and black text box - you will likely have much greater success importing and using the drawing in FlexSim.

It's possible that your computer needs upgraded graphics drivers to properly show the drawing, or your computer may be slower loading the file than my computer. But in either case, simplifying or removing the 3D geometry in the drawing file will most likely fix the issue.

I've attached the model where I imported your drawing file. It also takes my PC around 10 minutes to load this model (due to the drawing), but once loaded, my graphics card handles it fine with a decent refresh rate (I do have a pretty beefy graphics set up, so if your graphics hardware is older or weaker, the experience might not be adequate).

Let us know if you're able to simplify the drawing and how it goes for you.

Thanks Ben. i have a pretty decent work station so i don't think my graphics card will be the issue. Whats weird is when I try to import the DWG my flexsim does not become unresponsive. If it did i would have waited it out. i will try to import it and let it sit even though it is not freezing on me.
