project tool in sketch, there has to be a better way!

ok here's my issue:

I have a lot of tapered bosses on a plate. and I need to extrude from there top surface strait up rather than continuing with the taper. "think a block of chocolate"

so I could go back and remake the part so that it has the shape I want. in this case that wont work

but instead I go into sketch and project the boarders of the bosses to give me the projection lines.

project -> loop ->

click a face -> (that's 1 done)

click a face -> click next -> ( that's 2 )

click a face -> click next ->click next -> (3)

click a face -> click next ->click next ->click next -> ( 4)

see where I'm going with this.

its a really slow way of doing it,

surely there must be a way to go project and then go , this face , this face , this face , this face , this face , this face, done

projected lines selected

extrude

or a project everything on this surface button

if I can do it in other cad packages i.e. solid works or inventor and its pretty standard then why isn't it in Creo.

am i missing a secret command or is there just no way to do this?

note: in this instance ref pattern isn't an option as this block is cut from another part, and its too simple to program something in relations as that would be a waste of time as well.

Re: project tool in sketch, there has to be a better way!

I tried to recreate your problem and I couldn´t.

In native files a good solution is to copy the surface and the use the thicken command.

On imported files the Project/Loop is also a fast solution.

You can even use udf´s or mapkeys to speed up the process.

Watch my short video, maybe it can help you.

Sure, you make one and pattern it but for the most part, yes, tedious repetition is part of Creo... and WF... and Pro|E.

yup, that's what i was afraid of.. (

ill just add that to the list of things lacking in creo.

Re: project tool in sketch, there has to be a better way!

Perhaps you could:

  • intersect the solid with a plane through the top surface (a bit dodgy given that it's theoretically touching the plane rather than passing through it);
  • extrude the curve resulting from the intersect?

Re: project tool in sketch, there has to be a better way!

You could create a plane at the mid point where the taper and straight extrude meet. Create a sketch on that plane for one of your chocolate blocks. Taper extrude towards the plate. Then select the same sketch and do a regular extrude in the other direction. Group the extrudes for the block and pattern it. Always use pattern for repetitive things, or find a way of making the feature so you can pattern it.

Hi, i am not sure this speeds things up, or simplifies the process, but did you consider copying the 'top surface' set & then 'thicken' the required amount?

Re: project tool in sketch, there has to be a better way!

You can do it in Flexible BUT it does not seem to be any quicker.

The quickest way is probably to remodel it from scratch. Which is probably even quicker then picking all those edges.

Thinking about it, did you try (again you need Flexible) Pattern Recognition on the bosses? Then do one, then ref pattern?

Re: project tool in sketch, there has to be a better way!

Honestly, unless you just expect the spoftware (ANY) software, to just do it for you automatically, I don't see an issue here. Copying a loop is quick, painless, and simple. What's the problem?

Re: project tool in sketch, there has to be a better way!

sorry i probably should have explained better,

this is a piece of tooling which is cut out from the product, so there is no pattern data, its also a generic part so the amount of bosses will change dependant on the parent product it fits.

i was hoping that i could avoid making a relation driven from the parent other than the initial cutout.

and i could remake it so that the tooling drives the product, but thats backwards

what i was hoping for was something like the way you an right click several times to "select every line on the surface" when making fillets. or like in Solidworks where you can just click on several faces and extrude. from the profiles it automatically generates.

pro e just takes a long time to do certian things.

other things it's amazing at

but this is one of those things that grinds my gears a bit, that and not having a (center of 2 faces plane command) < again i might have missed that one as well.

hrmn worth a look.
