I'm moving my first steps into Houdini, starting with the quick start tutorials.
Right now I'm stuck with what I think it's a simple operation.

Just for the sake of learning, I'm creating a circle, extruding the faces and here I'm already noticing something which confuses me a little, let me show you with the help of some screen grabs:
circle


extrude & scale


delete unwanted poly


extrusion


unexpected, the base now is “empty”


preparing for polycap:


after polycap:


Now, let's do the same in Blender:


after extrusion


bottom is filled as well


pretending it wasn't and that the result was same as Houdini (let's delete bottom faces then)


select edge loops and bridge them out


done


mesh is clean, as it appears after a subsurf applied


So, I'm confused what happened in Houdini after the first extrusion and why after the poly cap geo is not clean.

Perhaps there's a different way to do this in Houdini..

Any hints?

Thank you Mantragora.

Play with houdini's modeling OPs by all means - it's a familiar ground as far as concepts go and will allow you to get in touch with the way Houdini works.
If you intend to model something more “serious” (perhaps even for a production god forbid) I strongly recommend you to keep modeling in Blender for the time being.
You'd probably reach that conclusion yourself soon enough, I just wanted to let you know “it's not you”

There is a free Bridge modeling tool on Orbolt. If you don't know, Orbolt is kind of like the Blender Market place.

Good to know, thanks McNistor.
I'm still familiarizing with Houdini, that's why I thought it was a good idea starting from the basics. But since I'm mainly interested in particles, perhaps I can move on and skip some of the modelling for now, after all no matter what 3d app I use I always go back to Blender for more challenging modelling, at least I'm very familiar with it.

Thanks for the heads up Enivob. Right now the site seems to be down, I'll try again later.
