  • Sometimes Auto Circle (or etc) puts th path abov the desird circle instd of on th CAD

    Pic attached. Please see the dialog box settings, it seems like I have it set up normally and that it should place the path on the CAD surface with this configuration.

    This will happen randomly (on any program I make, ever since the system was installed brand new) and can be eventually fixed by clicking on other features and back to the feature I want.


    The following is the code I am currently working on, where I am inserting an auto-circle at the end, but this is just one example. The glitch happens at random on any CAD I am working on.


    Code:

    I believe your Auto Circle path is above your CAD because you have a depth of positive .375. For outer diameters, you depth should be negative. For inner diameters, your depth should be positive.

      I know that changing it to negative will force it the opposite direction, but I don't seem to remember it doing it consistently on OD's as opposed to ID's. The Hexagon class definitely did not ever mention anything like that. I feel like it happens on ID's as well, but I only have this example at the moment.

      I will test out your suggestion and share my results, thanks.

      It's crazy how many little things PC-DMIS has that you have to "just know" that aren't in any Help files or manuals or anything. The whole classroom course at Hexagon went over Auto Features and never once mentioned anything like this. I even have the course manual at my desk and it doesn't say that. Ehhh... oh well.

      I cancelled the circle, and clicked it again for another circle, and this time it used the same positive value but put it in the right location. PC-DMIS is just buggy and does this nasty stuff all the time, all day long. I have had endless problems with Path Lines in the graphic window. Half the time they won't even show up when I toggle them on, and I have to restart the software and reopen my program a few times before they will show up. Then when they do, I have to make sure they're even showing up in the right place

        I'll try that. I never use it anyway since I prefer to manually create my move points

      In all versions of PC-DMIS I've used since the turn of the century I.D. autocircles move down the vector with a positive depth and O.D. autocircles move up the vector for a positive depth.

      That being said, I wouldn't put it past the Hexagon Imagineers to re-invent the wheel to make it hexagon shaped instead of circular or to rework a feature to make it different after 20 years.
