Modeling simple bar

[ghost]

Hello,

I am trying to model a simple Aluminum bar

with the dimensions shown (in mm), but instead, I am getting 6 bars (one for each face) that are 500um thick each. Is this normal?

<solids> <box name="WorldBox" x="100" y="100" z="100" lunit="m"/> <box name="board1" x="0.0603201" y="1" z="0.0005" lunit="m"/> <box name="board2" x="0.142635" y="1" z="0.0005" lunit="m"/> <box name="board3" x="0.0603201" y="1" z="0.0005" lunit="m"/> <box name="board4" x="0.142635" y="1" z="0.0005" lunit="m"/> <box name="board5" x="0.0603201" y="0.142635" z="0.0005" lunit="m"/> <box name="board6" x="0.0603201" y="0.142635" z="0.0005" lunit="m"/> <box name="testPart-1_Box" x="99" y="99" z="99" lunit="m"/> </solids>

How can I just get one single bar in the gdml output file?
Thanks!

This behavior is the default. SolidWorks stores the faces of the bar, and those are what the converter reads out of SolidWorks. The issue is how the converter can distinguish between a solid bar and a hollow rectangular box. I will have to investigate how SolidWorks represents these two cases.

If you could create a SolidWorks 2018 assembly with a solid bar and a hollow rectangular box with a slightly different size, that would be helpful. Then please post a link to the assembly and all its parts.

I will be on vacation until January, but I can look into the issue then.

Carl, Thanks for your prompt reply. Here's the requested files with three different methods of extruding the rectangular sketch in SW2018 (maybe there's another method that I'm unaware of to accomplish what I want?). I am using windows 10 64 bit. After I make the part, I make a SW assembly file of the part to use with SW2GDMLconverter. ~Daniel Le sam. 22 déc. 2018 à 17:34, Carl Vuosalo <[email protected]> a écrit :

Here are the files.

Any insights as to what is going on? @cvuosalo Thanks!

@danielmtzz: I looked at the files you posted, but they are not what I need. I would like to look at the SLDASM and SLDPRT files for your model so I can see how the bar is represented in SolidWorks.

Here they are. Sorry for not getting you what you needed before!

@danielmtzz: Thanks for the models. The problem is that SolidWorks provides the faces of the bar, but it is difficult to tell whether they belong to a solid or hollow bar. Currently, the converter assumes the bar is hollow. I have to think about how the converter can recognize the faces belong together so it can assemble the solid bar.

Makes sense. Thanks! @cvuosalo

@danielmtzz: I need realistic models for comparison. The bar_SurfaceAssem model has zero mass. Could you please make a model of a bar that has a complete surface (no holes) on the outside but hollow on the inside? Please give it a reasonable mass and specify the material name. Also, it would be good to include a material name for the bar_Assem. If I can compare more realistic models, I can see how SolidWorks represents the hollow bar vs. the solid bar. Thanks.

Carl, I found another way of doing it. No need to keep working on this. Thanks a lot for your help. ~Daniel Le ven. 18 janv. 2019 à 22:47, Carl Vuosalo <[email protected]> a écrit :

Could you explain us how did u solve it?
