Macro to Create Point in Isolated Surfaces

[vikt]

Hi everyone,
i have a product with multiple L Shaped bracket.
Problem is, all these brackets are Isolated surface.
Now each bracket has a hole( some may have two ).
I need to create a point to the center of this hole.

Request all to provide some solution or pointers, where i can try or create something.

Regards,
Vik

would it work if you took a boundary of the bracket surface, disassemble it into domains, loop through the result and If there is a circle curve present, create a point on circle?...

Hi LWolf,
I understood disassemble, loop and circle curve.
When I tried selecting the whole surface and disassembling it, after disassemble, all entities are coming as Surface.1,Surface.2 etc.
How can i select the boundary or edge, so that i can get the exact whole surface ?

take boundary of your Isolated bracket surface. the disassemble should be performed on the boundary curve (the boundary curve should consist of at least 2 domains, the hole and the outer boundary of the bracket surface... )

I guess you could do: disassemble (=> surfaces), boundary(=> edges), now loop through edges to get the "circled" ones.
Is it really worth scripting this? Do you have that many points to create? Are we talking hundreds, thousands?

 

[vikt]

Yes, i have hundreds of brackets in one product and there are multiple such products.
Selecting each bracket and creating boundary->Disassemble-> and then center point won't work. That's why an automation approach is needed.

Is it possible to post here such a bracket to have a go at it?

 

[LWolf]

I have given you the pointers, now you just need to implement it in form of a script...

Hi

You can do a search for Type=Edge,Selection_BorderREdge" and then loop inside selection and create your points (something like here, minnute 7)

Hi,
ferdo this will work if i have a solid body.
But here i have an isolated surface. When i disassemble it, i get approx. 50 more surfaces.
From there it is very difficult to find the surface which represent the hole in the bracket.
This is what i have so far (manual approach)
1. Select the isolated surface and disassemble
2. Identify and Manually Select the surface with hole and create Boundary
3. Disassemble the boundary
4. Now Join the boundary edge of hole and create a point



As you can see, this is tedious approach.
Let me know if we can automate this, just need the pointers, so i can start developing the script.

Regards,
Vik

Okay, so here is final solution.

1.Disassemble the master surface.
2.Create Boundary for each Isolated Surface(except the master surface)
3.Disassemble each boundary feature
4.You will get Line and Circles, loop through circles and Join them
5.If join is created, it's a full circle i.e a hole, use this Join to create point

I am working on automating it

Thanks LWolf for the idea.
Also everyone else who gave their valuable feedback.

Vikt, why don't you create a boundary for the master surface straight away?
Dissassemble into domains, not cells-- you will get full circles.
could you provide with an example file?

Hi LWolf,
sorry for the late reply.
I tried to create a boundary for the isolated master surface, but getting below error.
"Boundary operator: the selected body is closed, it has no boundary.
It is the case of a sphere as an example.
Select an open body."

It's an L shape profile, with holes.

regards,
vikt

can you post a picture of your solid?

if you have an L shape with a hole, maybe searching for all face and trying to create an axis with it will help you find what you need,if the axis construction is ok then get the boundaries of that face and build centre points.
