Dear all,
I tried converting .stl files into solids by first generating shape from the solid in freecad software. There i converted the file into .stp formal with solid geometry. Then I opened it in autodesk inventor to stich surfaces and check whether my geometry is solid or not. In Autodesk inventor it is showing that it is a solid part. I also tried importing the same file in Catia. There also it shows that that geometry is solid. Now the problem is whenever I import that solid geometry into Ansys workbench it shows that it has many surface bodies and my complete geometry is getting distorted. Please suggest me a way to convert .stl into solid without loosing its integrity.
I am attaching snapshot of all the process and problems I am facing.
kindly help me.
Hello,
First, you should do reverse engineering with CATIA (to have a uniform surface). So you need a lot of skill in CATIA .
It's not possible to teach reverse engineering here.
In some cases it helps a lot to set "simplify geometry" to "yes" in workbench.
Thank you for your suggestion. But still facing the same problem. Now more geometry is missing. I even tried heal bodies, tried to import only solid nor surface or lines for a try. Still results are somewhere same as it was before.
try to import the files directly into inventor and convert them there into the target file. inventor should support solid export. at least the latest version.
Thank you for your response. I tried converting it directly in inventor 2017 by using ''mesh enabler'' addin to convert it into base model. But when i import that file in workbench now rather than surface its shows part body and still i have to input the thickness manually. its just same as the surface. still not getting the volume solid that is required.
If you are tried to import the geometry files into workbench use one of the parasolid format. It will helpful whatever geometry name you are given in solid, the same thing show in design modeller workbench.
Hello,
Some solutions:
If you use Solidworks you can try this tutorial :https://grabcad.com/tutorials/how-do-i-convert-stl-graphics-to-a-solid-model
With Autodesk Inventor : https://grabcad.com/tutorials/tutorial-convert-stl-mesh-to-solid-file-in-autodesk-inventor
With Creo: https://www.youtube.com/watch?v=ho-t5OgEbJY
And a Free solution here: https://www.youtube.com/watch?v=tHT5FusXZ8s
Hope it will be helpful.

You should try to first import in a cad system, then convert it in a solid part. This part will be used with Ansys.
I recently found myself on the same situation.
Doing some research on internet I was able to find this good tutorial:
http://blog.bantamtools.com/convert-stl-to-step
But the FreeCAD software seams to have some limitation on handling complex shapes. It may work for you.
I found a website to convert the file for me. So far they are a free platform. I recommend to give it a shot.

Good luck!
