This is a long shot, but I have some old software running on the floor that will accept two lines and an arc that are "combined" using Rhino Cad, with a join command. When I look at the file that mastercam creates, i.e. open the iges file with a text editor, it is missing entity type 102, which is a composite curve. I've tried all types of splines, and I don't end up with that type of entity. Unfortunately, the software on the floor will only recognize the Rhino files (which weren't made by us). I'm not sure if Mastercam is capable of creating a "composite curve". Here is a Masercam iges file...The Rhino cad will have entity type 102.

The double if statement, basically, failed the test, and then output the results. I tested it, by forcing the output, and he was correct. Sorry for the delay..... Gail

I got it...Thanks...I was trying to adjust it through the post...I forgot the $... Gail

The switch is still in the post (spaces$ : 0), but it doesn't seem to work. I need to adjust it to zero (which it is already set at), but the output isn't changing. Is there something I'm missing in the control def.? I have changed it to 2,3, etc. and it still doesn't change. Gail

I talked to my reseller and he explained why it worked...

I was adjusting a post to get the desired output today, and I "accidentally" put in two if statements...example if if xxxxxx, yyyyy versus if xxxxx, yyyyy The funny thing is, the double if gives me the correct output, and the single if, doesn't. That is really strange...Has anyone else done this? Gail

You wont find optimize if you are using lathe. I have complained about this before...I use control comp all the time (because we can't maintain stock on inserts).

You would be better off explaining what you need, and we could offer some help.

The .ops file, not the op9 file. I know what that one is for.. Thanks, Gail

It must be flawed...My parts still have burrs.

Any thought?

I went ahead and did simplify, and it converted 1 spline to an arc & 2 splines to lines, and then reported, "1 splines were converted"..When it actually converted 3 (1 to an arc, and 2 to lines). Any explanations?

Why do my masking options shut off when I click Edit Trim/Break Break Many pieces Arcs??????????? Is there a way to do this...All/Splines/Done?

I found it in the backplot options....

When I backplot on one machine and step, I have a whole bunch of information on the bottom of the screen, i.e. spindle spees, feed, cocordinates, etc. On the other machine, I only get the coordinates. How do I turn this on and off? gail
