Can you reduce/delete smesh nodes?

I've got a smesh I made from a hemisphere.  I need to reduce the number of faces because there are just too many to work with in this case, particularly at the center where several edges converge to the center.  So I selected several faces and merged them together.  I did this to create a smaller quantity of faces.  Problem is that, between two faces, I now have a series of nodes/edges between two faces when, theoretically, there should only be one edge.  I only need to move the nodes at the intersections of faces - I don't want to move several nodes along the edge of two faces as that would add an incredible amount of work.

I would think that when you merge faces, you'd be merging nodes as well.

Try node editing using the selector mode.  It's effectively what some other apps call "soft selection", and translates the nodes within the selection set proportionately to the bounding box of the set, ie within the boundary described by the outermost nodes, instead of moving all of the selected nodes an absolute increment.  It'll lessen the workload, but not  eliminate it.  You're not deleting nodes within merged faces because in most cases of true freeform subdivision modelling from a smesh primitive rather than changing object type, you're merging faces which are subsets of loops, you're not merging full loops.  TC doesn't have what's called "decimation" in some subD apps, which is the sort-of "un-subdivide" that I think you're looking for. 

If all else fails, make a copy and try out TC's surface simplification tool on it.  It might help.

Surface simplification tool?  I can't find anything at all on that.

So there is no "decimate" function.  Interesting.  You can delete nodes in a polyline but not in a smesh.  I find it amazing that absolutely every project I take up, whether one of my own or for a paying customer, I run into the strangest things, such as this.  It's maddening.

Modify|Modify 3D objects|TC Surface Simplification.  Smesh is an addition to a CAD program, it's doesn't make TC a subD modeller IMO.   If the face that you're merging is in fact flat, you might find that turning your object into a solid and then back into a smesh object does remove the nodes.

Sorry, but I have to ask.  Do you know that you can control how many nodes are produced before you start Smesh modelling. I'm guessing you do, but thought I'd ask just in case.

Hi Jamac, pleas, try this way with SMesh tools. It may help you!
