Creating 3D-pipes out of polyline-shapes

Hi,

 

 

have you tried to insert a PathSplitter and an ArcStroker first?

Hi David,

 

 

I am using the chopper to get the segments out of the polyline. The Arcstroker has no advantages for my work, because there are no real arcs within my data. They "curves" already constist of several segments.

 

The main problem is, that the extruder can only extrude the profile of the pipes along Z or a vector, but not along the whole polyline.

Hi

 

I think you're correct that you can't do this with the whole feature. I would try your workflow if I had to do this. But what you can do to improve the output is perhaps densify the lines. By using a Densifier you can create more, smaller, vectors - so there will be less chance of spaces.

 

 

There is already a request to implement this (PR#25466 in our database). I've added a link to this page and increased the priority, but if you have any other information you can supply - for example a good business case for us - then it could help get this implemented more quickly.

 

 

You can contact us privately through the support team. Also, if you have some sample data we can use to develop/test a solution, you can pass that on through the support team too.

 

 

Hope this helps

Please take a look at the 3DBufferer transformer in the FME Store. It will make pipes with rounded elbows from 3D lines. Also creates solids from points and polygons.

I already looked at it. It helped me changing my own project, so that I can add the missing parts within two pipesegments. I didn't know so far, that the clipper is able to create solids. So this was the thing, that gave me the right ideas.

 

The 3D-Buffer is nice, but it creates to complex pipes (to many polygons) and the round elbows are not what I want the pipes to look like. I also wanted different kind of pipes (not only round).

 

 

Now I only have one problem within my project. These pipes I am creating at the moment are looking nice within datainspector, but exporting them to DXF or ESRI-shape creates vertices, that I don't understand, where they come from. Perhaps I can "repair" this by using triangulator before export. Hadn't time to test this so far.
