I imported a dining chair into Rhino 8 and the chair legs have a lot of ‘faces’ if that is the correct term (still a newbie). I tried the ‘Merge all coplanar faces’ but it did not have any effect. What else to try. Redrawing the leg? Or is there another command to use.
Here’s a screen shoot of the chair in monochrome.
Hi John -
The legs are curved, so the faces are not coplanar.
You could just leave it as-is.
It’s always better to post a 3dm file, but from that image, it looks like this object was converted into a poly surface (from the original mesh object). In Monochrome, the mesh object will probably not show all those edges.

also, building this chair from scratch does not take more than 5 minutes, 3-4 extruded curves and some blocks, in this case even quicker since you already have a model to draw from.
I imported in the Sketchup with both the Trimmed Planes (the one shown) and Mesh checked. Both looked the same. Sounds like to just leave it as is. I’m pretty new to Rhino 8 and have been watching a lot of demos. From some of the more advanced ones I’m amazed what the presenters can do in such a short time. I will grinding away until I get up to speed. Anything with curves, the legs, I want to eventually be able to cut them out on my CNC.
I used Sketchup for years until they went to the rent a software model and found things I didn’t like about it. One of the things I did like about Sketchup is that there was large following of users doing woodworking designs and modeling in Sketchup. Do you know of a similar concentration of woodworkers using Sketchup? Most of the Rhino furniture designers I have found on the web are doing ultra modern furniture, sculpted synthetic materials and such. I’m more interested all wood design.
Sketchup is a poor choice if you are sending files for CNC.
It produces only meshes, and while some CNC software can machine from meshes, you’ll have far less control with how those meshes are created in Sketchup.
A lot of CNC software will internally tesselate (mesh) an imported nurbs file, such as STP, Parasolid, etc in an optimal way for producing a toolpath.
Some CNC software will machine directly from an imported mesh (not having nurbs solids import), and using Rhino you could generate a mesh yourself from your nurbs model.
Hi,
Thanks for the reply. That’s what I intended with the import, use it as a starting model, as there are modifications I would want to make. Albeit, I imagine it will take me more than a good deal of time more than a few minutes, :-(. I always like to master a tool, application. Rhino is so feature rich that is going to take a while.
Hi John -
I answered that one here:
You still didn’t post the 3dm file, but I’d probably extract one side of the legs of the NURBS version, extract the border, explode, deselect the top and bottom horizontal segments, join, and Elmo (Rebuild) the side curves with as few control points as possible. Then extrude those to a new polysurface.
Hi,
I use Vectric Aspire for producing CNC files. I import the section of Sketchup I want to cutout and make any modifications in Aspire. That works until it is something more involved architecturally needs be drawn. Most of the woodworkers in my guild told me don’t use Rhino but use 360 Fusion. That doesn’t work for me because when I travel I like to work off line where there is no internet connection. Additional benefit of Rhino is that it runs on both MS and Apple. I have a powerful Macbook that easily runs Rhino.
I used Sketchup a lot for my woodworking designs but I don’t like the rent a software model and started to find it limited. Rhino on the other hand has an amazing array of features. Additionally, Sketchup support pales in comparison to what I have gotten for Rhino. When I view some of the more advanced videos and see what the experts can produce so quickly, it is amazing. There is always the frustrations of the ramp up period and wanting to be productive in the woodshop. I’m plugging away at the online learning sites, reading the blogs and forums.
I only hope to be that proficient. I learned sketchup well enough to design a 3rd model of my home which then a real designer did house plans but Rhino is so much more feature rich than sketchup it is taking me more time to ramp up.
