Delete associatve entities and a ? on Maitenance

[Thee Rickster ™]

Quick question.

 

I use X2 SP1

 

I imported the cast model and I imported the

machined model for reference.

 

I completely designed my mold components using the

cast model. I did not use the machined model for

any thing. I have not made one toolpath yet.

 

i moved the machined model to a different layer

and the layer that it was on had the exact same

amount of entities as if I copied it.

So I opened the old layer and found nothing

untill I unblanked the entities.

So I deleted them, and to my amazement both layers

became empty, rid of all the (machine models)

entities.

 

Why does this happen?

 

 

Also, Is the big file size problem fixed on

X2 MR2. Or any of the Service packs above the

version I am using. (Large files hang on tool path

generation over 100 meg)

 

BTW, I will be getting maintenance before the

end of the year.

 

Thanks

Rick

Rick we import much geometry form ProEngineer

and have had the same problem, as we can determine

depending upon how the original geomety was constructed and what software was used associated

entities must not be lost. Any original geomety that was used for creation that is erased will erase any built on top of it, much like MC solids.

If you create geometry to extrude or build upon

a solid model, then delete the geometry after extrudeing the protrusion or cavity created may not be reproduced. If you used geometry from the cast model cast as a foundation and then removed the foundation, all built on after the cast part will fail. One work around is to have the original

copied as a dumb solid, or shrink wrap, and if possible use that as a base.These types of files

do not carry associated entites with them, therefore files are smaller. Also MR2 now gives

the option of deleteing all or only non associated enities

Where can I find info on these things you

suggest?

 

ThanksRick

That would be done by the designer using

the same software that was used to create the part.Basicly it is a copy of the part made from the original without and construction geometry

or assocated enities.

There is a nohist dll chook that will give you a "dumb" solid.

What I've been doing is, when I get a model, take the viewable entities and move them to a different layer. Then go back to my blanked entities page, unblank everything and move them to an unused layer, label them "Blank", then move everything else back to the original level.

 

If there is any way to "break" the association to entities I would like to know, because some of our models are huge, and those unused associated entities are taking up alot of my valuable processor space.

If it is a surface model... no dice, the parent surfaces are necessary, but the wireframe is not.

 

If it is a solid then you can parasolid it out then back in and it is dumb. Or the nohist chook +1 3rd string.

 

Dumb=no associativity to anything...self-defined.

I renamed my config file and restarted mastercam

all is well.

 

I was having other problems where I rotated the

geometry for the cavity on 4 layers and it all moved

to different layers.

 

That was rectified as well

 

Thanks all

and

In-house Solutions for the quick response and

speedy fix to my problem.

What I have found to work when a toolpath hangs is to open internet explorer and bounce around opening different web pages. That will almost always get the toolpath processing again.

Carl, I noticed the same thing. Porn sites work the best.

[Carl Hessig]

I think that just causes excessive tool wear.

I should have known this...
