Could someone please post the links where cuter compensation methods are debated. Thanks in advance.

I have my share of STL problems as well. I'm not at work but have you tried Xform STL to move your .STL file where you want it? Sorry if this doesn't help as I have not tried it myself yet.

I put a Pro/E IGES file on my USB portable drive and took it to a shop this morning that has the extra cost Mastercam Solids that we don't. The Solids From Surfaces tool worked perfectly. I can see where this would give me another option when STL fails for use with Mastercam Verify. Is there an STL repair tool we could buy to fix the STL so Mastercam Verify would recognize the shape and I could use it for Verify? "Ask for a STEP file from the Pro-E supplier." They are a large company. All they want to provide is Pro/E IGES so that's what we have to use. "You can actually use solid edges and faces to "Chain" for use in milling toolpaths." I frequently use Mastercam's Xform Project tool to copy wire geometry from a different Z level on the part that I want to use for my toolpath. I don't think being able to chain solid edges and faces will eliminate having to use the Xform Project tool. Am I missing something in my understanding of what you said about chaining solids?

"You can also use the solid to verify your toolpaths." Since I'm having so many problems getting Pro/E IGES files to create an STL that Mastercam Verify can use perhaps this might be an option. If we purchased the Mastercam Solids upgrade how would we go about solidifying the surfaces that are in the Pro/E IGES file into a solid? We are stuck with Pro/E IGES as the only file we can get.

Andy, Mark, I shade the surfaces that Pro/E creates when the files are saved as IGES and get the same visualization as a solid.

We are using X2 MR2. I create a new WCS for every new Toolpath Group. "If you use the WCS, you can set everything up and verify using one blank which will help that error from not occurring". This is what I want to do in this case. I already do this when I'm machining the entire part. Often I get an existing Pro/E IGES file and I am asked to add features to the existing part. I wish to start with the existing shape of the part so that Verify will be accurate. I can't do this because with this file Verify defaults to a block after giving the error - "LW has found the STL file not to be closed and water tight. An approximation will be used for stock." This defeats what I'm trying to do which is to start with the existing part shape.

I mostly work with imported Pro/E IGES files. Almost all the work is two and a half axis milling work. What benefit if any would we get if I had our company upgrade to Mastercam Solids?

I think what Chris Rizzo posted will help me out. The reason I say I think is I ran into another problem at work today. I get an error message. The message is - "LW has found the STL file not to be closed and water tight. An approximation will be used for stock." Is there a setting I can change for Mastercam Verify so that this STL file will be closed and water tight? The IGES file is from Pro/E. I mostly get Pro/E IGES files to work with.

I have an imported IGES file of a part that needs a few features added and machined. I set up a new WCS for the part and called it OP-1. I made OP-1 my current WCS and made sure both T plane and C plane were checked for the OP-1 WCS. I then saved this file as an .STL file so I could use it as the start point when doing verification on the features I added to this existing part. In Verify I choose the .STL file I saved but the coordinate systems is in the wrong place and Verify cuts the feature on the wrong side of the part and in the wrong place. Can someone tell me what I'm doing wrong? How about a step by step on how to use an .STL file for Verify?
