Int. Colin, Without knowing the geometry and the code generator I'm just speculating, but if you're suppressing the XY position output for some reason, I would recommend putting the #UPDATE() command in the same place where you're suppressing the output.  Certainly, you can put it in @ARC to confirm whether this is the problem. If you're not intentionally suppressing the XY position information, but it's not coming out for some reason,  then you should determine why it's not being output rather than using #UPDATE(). If you're getting the correct positioning information output but the IJ vector is wrong, then the problem is more complex, and #UPDATE() will probably not help. --gregg   Colin Williams wrote:  Do I put the #update in the @arc section? Thanks, Colin -----Original Message----- From: Gregg Olson <[EMAIL PROTECTED]> To: Colin Williams <[EMAIL PROTECTED]> Cc: Smartcam Forum <[EMAIL PROTECTED]> Date: Tuesday, June 27, 2000 2:53 PM Subject: Re: [mfg-smartcam] Circ. Int.  Colin, You've asked why the bad J value is comming out. From the data you've provided, it appears your arc center output requires signed incremental IJs.  It also appears that the calculation for the IJs in this case is being based on the previous arc rather than the current one. This implies that the current position is not being updated properly for some reason.   I would check to see that the move to the new start point is being properly output.  If for some reason you are suppressing this position from being output, you need to do a #UPDATE() on #XPOS & #YPOS instead, so the system knows where to calculate the IJ vector from.

Looking at the attachment when I circ. interp. the 2 bottom parts (horizontal m/c)the G02 line comes out : G02 I-.2985 which is fine. But when I circ. inter. the top parts the G02 line comes out: G02 I-.2985 J5.0 which is not fine. If I did the top parts first the G02 on the bottom parts will be: G02 I-.2985 J-5.0. Each part has its own fixture offset(workplane). The "J" value seems to be coming from the the top or bottom parts depending which I do first. My question is why is the "J" value coming up. I hope you can understand this.  Thank You Colin Williams -- Gregg Olson Development Manager SDRC CAM Products -- Gregg Olson Development Manager SDRC CAM Products
