why is x3 doing this?

[veritasproject]

if my file is a little complex i start to loose some of the faces on my surfaces ans solid there still there it just looks like there gone

 

any help would be awsome

[iowajim62]

Go to Settings/Configuration/Shading and check to make sure that the "All entities" check box is checked. Hit the Green Check mark and try shading again.

I am curious as to how that file got into Mastercam?

 

Was it an iges?

 

I've seen things like that on ugly iges files, mainly out of Catia

[RobertELee]

I think John may be right. I've had IGES files like that come out of ProE. Saved it as a STEP and everything came in fine.

I think it is memory/video card issue. I have seen this too on large part file with alot of solids in them. Try getting out of MCX and re-opening the file. It works for me.

I agree.. make sure the "disable back buffer" setting on the Screen page of System Config is checked.. You don't say what video card

you have, but turing that setting on may help.

If this cheap video card was the answer, I HATE to ask what the question was.

 

You CAN get by with a GOOD GEForce card by buying something out of the $59 bin, isn't going to get it done. Sorry but that is just how it is.

 

In an ideal situation you would have installed and NVidia Quadro card, those are the CAD/CAM workstation level cards. In a less than ideal situation, a GeForce Card, I would recommend NOTHING less than a 9800 card, an older 8800 works as well, I run 2 of these.

Try Screen-Regenerate Display List.

I see this quite a bit. It is definetely a Ram issue. Just like the verify problems. For some reason Mastercam does a real poor job of handling Ram. If you will elave your task manager open and set to the performance you will see that Mastercam does not let go of Ram in the page file after you verify. So what I am saying is that if you verify the same part say 3 times in a row you will see the page file just keeps growing. You can also open a blank file and see that it still hangs on to the Ram until you restart Mastercam. I will agree that it is a graphic issue but I think it is more directly related to the Ram hoarding.

 

retstaring MC is the only help I have found. Also I don't remember this being an issue in X2MR2.

[Mark H]

If the part is unshaded, can you see all the features?

 

I agree, its most likely the the video card. I would try gcodes suggestion - "disable back buffer"

 

Also in the Shade Settings, try changing the "Chord height" parameters to a looser setting.

[Guest]

Just an FYI guys, a GeForce card doesn't have a back buffer. Disabling it won't affect anything.

[cobra95kev]

I think Ray is on to something too. I have noticed what he says also. Sometimes after MCX has been open a while on the same file if you use verify alot it will kill use up all of your memory.

[gcode]

In X3 I would sometimes have to

restart MC after running a large

Verify session. X3 MU1 seems to be

doing a better job of this

[X-L Engineering Corp]

I've also noticed it only after running a big file thru Verify even with X3MU1.

[Ray H.]

ya unfortunately i have not found another way around this. All the RAM and best graphics card in the world won't fix whats happening here.

my computer is older and it has pci slots not pcie so i could not get a quadro. i never had this happen at my old job. i have only been with compart olny 4 months. on top of all that they got mastercam just for me befor i started here and the mastercam reseller told my new boss that mastercam would run grate on an off the shelf pc, so it would be hard to talk them into getting my a new work staition. so the video i have is the best i could find for a pci slot

[Mike S @ S4A]

Did you get this advice in writing?

We're inclined towards self policing -

Bad advice from one representative reflects on all of us.

[veritasproject]

i will look up her name but she is out of orange county and she told my boss that he would not have to buy anything and it would run on any pc.now this all happen before i started here. i know that the better the pc the better mcx runs

[veritasproject]

will let me say mcx run on this pc just not very well:(

[veritasproject]

ii just spock to the repesentative and it would seem that she did not know very much about run mastercam all she could do was tell me the min. specs for it to run and then she just pawnd me off on the i.t. guy who i should upgrade to a new workstaition

and I will tell you that unless you are doing SIMPLE flat 2D work, the minimum specs are WAAAAAYYYYY below what most users should have.

Mastercam Spec workstaions from Dell

If you have an AGP video motherboard,

this will help.
