Hello Christoph,

When I open the first object and do a Verify -> Check Obj there is a few errors found in the object. That could be the issue with adding objects and the quality of the step file.

Regards

Jason

Christoph,

It looks like it when there were multiple faces blended together see pic1 for where I am guessing the issue is. I would use the verify check object at multiple stages as you build the part, like when adding to bodies together or doing a complex blend then you can repair as you go. I bet it can't repair because it wont know how to fill the blends of many surfaces coming together at the same areas now that there is so much geometry added to the model.

I found an example of a bad face see pic2, when the blend or addition happened it looks like it had a bad point and created a bad face. You can use the remove face tool on the bad face in pic2, but finding the bad face in the area in pic1 will be very difficult but you can try.

Do you have a older versions of the file saved? I try to save the model after various major changes so i have an incremental backup to use if something happens. I also remove all splines and use the "Arcs from Curve" tool a lot to help simplify the curves before creating 3d geometry.


Regards

Jason

Hi Larry, hi Jason,

thank you very much for your effort !

Larry, great, as far as i can see, you just rounded one corner a little and suddenly the addition worked.
But how does it look if you re-import your STEP-Data?
On my computer it looks like that:



Don't worry, that "ghost snake" I got fairly often (and even worse), when exporting my part to STEP and re-importing to my ViaCAD.


Jason, I found an older version of my data which the analyser told to be ok, but those two examples of multiple or bad faces you show, are already there in that old version.



So i start again on that version and try to update all the modifications using the analyser and save to new versions fequently.
Maybe that works. We will see.

Thank you very much !!

Christoph

Hi Pomi!

I have imported the object in my 3D-Slicer-program "Simplify3d" and there where 2 massages

- Not manifold and

- Self-intersection areas

The Non-Manifold-problem I could solve by using NETFABB Online but the intersection-problem is still existing.
Is only a very small area, look at the picture.

I try to export the STL to STEP that you can use. Attachment is following.

I think, in a forum about a program we talk about it must be possible to attache all formats the program is able to transform.
Very annoyed.

... yes, as reason I would understand > to big, invalide file name, corrupt file ... but the messages was: Not Allowed!


H.

Unfortunately no, but a good idea for the next time, the relevant files are deleted.

If the detour STL > STEP is a possiblity to solve problems, everone can use Netfabb Online, it is free. In the internet perhaps there are existing other solutions working directly with a corrupt STEP-file; I don't know, I don't work with Step.

Try adding .txt as file type attachment to see if that'll upload, ie *.stl.txt. My office occasionally uses that as a workaround when there are restrictions on type. Trim it back after download it that works.

Will try as a zipped file with .txt extension.
Still doesn't work, same error.
