carved scan coming out small

[joepei]

i have scanned a dash vent from a 31 ford. The scan came out well and the carving looks good. The problem is the carving is coming out 1/8" smaller then the original. It looks like the carving bit is not offset and is carving the cut path to the outside of the bit instead of the inside. i have not had this problem in other scanned carves. Do i just adjust the size of the scan up an 1/8" to compensate?

Did you "flip" the cut path in the cut path settings?

[joepei]

No but i did save it directly from scan into the carve pattern tool list, so no cut path option was involved that i saw.

I was reading your statement as saying you were cutting it out.

Does the pattern dimensions match the actual scanned item size or does it show to the 1/8" smaller. If smaller you can set the size in the dimensions box in the Pattern editor and in Designer.

I am just getting back to this vent. I tried adjusting the size in designer, but when i try to save it, the program changes the size to a larger one again. I have attached a picture of the MPC. If you look at the rectangle that indicates the size, it is bigger than the scan. I think this is why the carve is coming out small? Any thoughts? The actual carve is coming out 6.0625' x 8.75. It should be 6.375 x 8.875.
Thanks

Are you doing this as a 2 sided carve like it is in the file you posted? If so, Increase your board size it looks like one side is masking out the other side. When I hide the back side the front side looks a lot better size wise.

[joepei]

Yes i am. So I deleted the back side and adjusted the size. When i highlight the image the size square still lines up on the left and top facing, but is off the carve on the bottom and right side.

I am not sure what you are seeing off of the board. Here is my view. Is there a reason you are making your board size so small? I would suggest going a bit bigger to insure it fits. How are you planning on cutting these out of the board?
