Dividing pentagon surfaces into quad and triangular surface

Hi all,

In the attached image, there are numerous triangular, quad and pentagon surfaces. I want to split only the pentagon surfaces into quad and triangular surface. This can work with a script which filters out the pentagon surfaces from a given Brep input and then splits it.

If splitting into 1 quad and 1 triangle is directly difficult, this can be done by splitting the pentagon into 3 triangles and then joining any two triangles to form a quad. Any idea how to script this?

Best regards,

Sushant

Hi Sushant,

This should do it.

It measures the length of a list and dispatches those greater than 4 to a routine which divides the list into a Quad and then makes a Triangle on the remaining vertex. Note it uses the Path Mapper to get the new list back into the sequence as before. This is the component that looks like {A;B;C;D} => {A;B;1} more can be found about the use of Path Mapper Here (but it does need updating when I have the time).

As usual data matching was the culprit.

I have made some mods to the definition and it should work now.
