replacing a hole after extruding through

Checkmate

Hi,
i have created a revolve cylinder with one solid end, (going to be a nest for a LED)

and then i have extruded through it.

What is the best way of replacing the hole in the middle of the cylinder?

thanks,
 
Checkmate,

Perhaps approach this in a different way. Since you know you have a hole to make, change your revolve to be a complete cylinder without the opening. Then cut out the hole as a later feature.

You can make this using surfaces too.

Checkmate, magneplanar is correct, if you try a different approach and add the hole feature in later. I take it that you want to replace a simple extrusoin with a threaded hole feature???
 
thanks, this is what i suspected! just thought there might be the off chance of a fancy automated way of doing it.

thanks,
 
You can also change your extrude thru to a surface and solidify it. I'm assuming there is a detail missing because what I see this should be a two feature part. An extrude and a revolve. Why cut a hole in the cylinder if you are just gonna be replacing it?

yea it is a two feature part. a revolve cylinder and an extrude that intersects the cylinder, but the extrude blocks up the inside of the cylinder and i was wondering what is the best way of getting rid of this blockage.

i have just tried making the extrude a surface with caped ends but after there is no option for solidify.
i have also tried making both features surfaces and after there is also no option for solidify.
although it apears if i only select one of the features then there is the option for solidify, but it only solidifys the whole of the extruded feature and the cylinder remains blocked. and if patch is what i should be using that is blocked out.

is there something else i should know to do this by solidify?

also you should be able to see two pictures, one with just the revolve and one with both of the features. no detail is missing.

thanks,

checkmate,


Unless I am missing something, can you not just put a new hole thru, or extruse a cut thru? Use the end of the cylinder as the sketch plane.

yea i understand that that is probably the most obvious way of doing it. i just wanted to know it there was an intelligent way of doing it so that the cylinder doesn't get blocked in the first place. in my opinion there should be an option when extruding to not extrude through holes or spaces that have been cut and previously determined. that would be a useful tool but now i understand that it probably doesn't exist and it also seems that there is no other way of creating the part without having to unblock the cylinder after.
 
Surely what you are describing is the same as just going into your model tree and dragging the Hole Cut command back below the new extrusions ?
 
no sorry that is not what i am describing. there is no hole! two features, a revolve and an extrude, the revolve has a hole in it because it was sketched like that and i was hoping that proe might have a way of recognising that i have created some negative space in my revolve had have an option to keep that negative space when i extrude through it. but i guess it can't do that and mabe they couldn't even make it do that even if they tried.
 
oh i see what you mean, yes that would involve a little more "intellegent programming" i guess, but you know that the answer pro-e will give you is, dont draw the hole in the revolve sketch
