… To turn trimmed surface into untrimmed surface? Hold on, to clarify that! I just created 4 sides surface, trimmed it 45 degree across and it’s now 5 sided surface. I wanted to merge this 5 sided (Trimmed) surace with another surface. Unfortunately, I do know <MergeSrf> don’t work on trimmed surface?
Unless there is Alternative tool that can merge trimmed surface? Any ideas?
True… I could build new on, But… My surface have 5 sides, and they are curved :shrug:Say, what kind of tool can develop 5 curved sides surface?
-Yes, I could use Planar Tool, but it require leveled/flat curves
-Yes. I could spilt up 5 side curves in boundry, in order to make 4 sides surfaces or surface in two on same boundry and merge them at last… but it would be difficult to do that since I’d have to move cp to get curve perfect up.
My brain is stuffed up, I wouldn’f know anymore ideas… any ideas?
Will this work??? I made 2 5 sided polygons a 5 and a 10, then lofted. I moved the inside line and placed a single point at 0,0,0. then I lofted the surface edge to the point…
I am sure you will have a more stratigic place to put your point, but looks likt it will work, maybe blend them after words…
Okay my brain isn’t workign to well today and I don’t really understand what your proposing but my suggestion would be _blendsrf… but it couldn’t be that easy :shrug:
Can you post images and I’m sure we will get a solution.
It is not possible to create an untrimmed surface with 5 edges. 
Why do you need to merge the surface anyway?
Well… Forget the first part I said… I just had to change around… by creating 5 side surface in flat and add planar tool in order to get surface then bend it and its now crved 5 sided surface.
Pointcloud… What you did was 5 side pentagon… With perfect distance on each sides… The one I was refering to 5 sides surface as unique odd shapes and its like concaved curves. Thanks for your help
Snecx, yeah It’d be nice if rhino could add more than 4 sides surfaces make life easier in some cases oh well… About merging surface… why do I need it? I just thought That is the way it could establish continuity. is it bad idea to merge them?
It is a pentagon though, I was saying the command. curve>polygon>select #sides in command window from 3 to how many you want.
I guess I am still not sure of what you are doing. But I tried… Could you post so I can see, I may never see one?{;->.
You know what, on second thought… I ll post picture tmw, since I am at work. I just want to make this thread useful for others who may encounter some problem, and this could benefit them from knowing how to solve it.
Yeah please post… if this is problematic it would be great to have the solution in full here on cgtalk
Here’s attachment of my problem… Unfortunately I don’t have that files anymore because I came up with solution… Anyway…
Problem: (Attachment 1) as you can see the base urface is trimmed up with 5 sides. I have tried to get them merged with “extrued part” of surface. No success!.
Solution: (Attachment 2) I spiled up base surface in 6 pieces. Then duplicate face border, remove the orginal surface then recreate surface with <EdgeSrf>.
Final: (Attachment 3) I merged them all, and its all good.
Reason: At my work, I had to mill this type of surface with CNC milling machine… My supervisor asked me to solve this issue because there were some error between machine and G-Code. I discover that surface requires to merge together between base and extruded part… in order to fix G-Code error. And now its all solved.
What cam are you useing? I never had that problem before. + you might be able to set be max Z depth in the machine opps part of the cam?
At my work, my company uses Icam for Large milling, and Ez-Cam or Ez-Mill for small milling. The model displayed above or problem I have encountered above uses Ez-Mill… Well, Actually I don’t know about cam that much, this isn’t in my department or my field… I just design model prior to customer’s request, edit the model given by customer using Rhino or AST, and correct/convert the model in G-Code in order for machine to understand what is need to cut and/or mill.
So the problem is… since base surface is already trimmed, and not merged but joined instead…It did not “inform” G-Code that the extruded part and base would need to mill together, Technically, it just separate and base part along extrued. When the mill cuts the base part into “House” shaping, the system calls error because they couldn’t find soild to mill. So it was model flaw… So I had to change it by merging base and extruded parts. Afterall, it was success! (BTW, in case if you know what the model was, this is a knob that other company requested. What strange looking knob eh!)
Now, it’s all forgotten, but I still would share with you in case you are interested
You should have them look into Rhinocam. You would not have had this problem…
Here is there post processor page. These are the machines that RCam currently posting for, but they will write what ever you need…

I used to use BobCad/Cam but I had problems with the model in BobCad/Cam, since Rhinocam I have had no Problems at ALL…
Our company knew about this plugin… Unfortunately it doesn’t make compatible with two of milling machines. From what I know, as of now the company that produce Rhino Cam is making progress on getting plugins becoming compatible on our machine and it should not be any longer. It’d be great to have this plugin soon so that way we, worker could get rid of old G-Code system since its really PITA, too much hassle when error appears and that it generate time consuming.
It is compatible with any CNC machine that uses G and M codes (S,F,&T).It even has a bunch of canned cycles already written. It will write for up to 5 axis (X,Y,Z,A,B)… Post processor’s for a spacific machine can be written in minutes… If your machine needs to be drip fed it can do that too… via eathernet, usb, or rs232… I post a .txt and load on to a usb mem stick, then up to the machine control…
Who told you something like that? hehehe…Maybe your machine programmer is just keeping his job!!! You could do his job and be better at it I’d bet… Contact MecSoft(rhinocam/visualmil) and see for yourself…
