Adding Breaklines to surface

arpenteur — Mon, 31 May 2021 14:37:11 GMT

Hello,

I just created a Surface. After, I added Breaklines to the Surface. After reviewing my Surface, it seems that the Surface is not recognizing the Breaklines. Am I doing something wrong? I attached the DWG...

Thanks

The surface has no breaklines defined...

Hi Jeff,

It shows on the image (attachment) that I have Breaklines attached to the Surface. I also attached the DWG. Do I need to offset the edges of the surface so that the Breakliones would be recognized? Not sure what I am doing wrong.

Thanks again...

Hi @arpenteur ,

It seems that you don't have breaklines, but a block reference.

You need to explode it and the add the breaklines to the surface.

Hope it helps.

Regards.

Hi Topmig,

I know that I created Breaklines along the Surface on both sides and in the center. So, how do I attach Breaklines to my Surface? I modified my Breaklines in my Profiles. That is why I need to attach the Breaklines to my SURF-TEST.

Can someone help me?

Here is a cleanup of my SURF-TEST in the attachment...

Not nit picking the nomenclature but we add break lines to a surface not attach... Maybe this distinction will elucidate

Hi Joe,

My first language is French, I may do some mistakes. I did not take this personally.

But, is there a way that you can help me?

Thanks...

@arpenteur I think C3D is not using the breaklines you added. I have a tool that lists information about objects, including if they are being used as a breakline, and which surface it is used in. I am not getting any linework to show up with such information in your drawing, until I add just one featureline as a breakline in a new breakline set. Looking at the 100+ breaklines you've added (first, that is a lot for a single set, better off making multiple sets) there are many with just 1 vertice, and many more with just 2.

I suggest just adding just a few breaklines to start, the centerline and edge of pavement featurelines. Also, be sure to use the Supplemental and Weeding factors. I would suggest 20 and 0.2 for these settings.

Hi @arpenteur ,

I think i undestand what you need.

See if i'm right:

You created a surface with a point group and several breaklines
You created some new feature lines to adjust the elevations, creating profiles for that,
You need to adjust your surface with the new feature lines.

I don't think that is possible, because you have points, that are the origin of the surface, forcing the surface to that elevations. When you add a breakline in the exact same position with a diferent elevation, the software maintain the original structure.

If it was me, i would create a new clean surface with the new feature lines.

Hope it helps,

Regards.

Hi Topmig,

This is what I needed, and it worked.

Thanks
