extrude to non-flat surface

[marcin.blaszczyk]

Hi,

I solved similar problem long time ago by "extend to surface" or sth like this (don't remember exactly).

Cannot repeat it now.

How to extrude to surfaces which are not on the same level (that would be a pre-part for modeling part for injection molding) ?

Extrude To

or

Extrude To Next

There are other possible techniques, like Replace Face....

[marcin.blaszczyk]

this is useful but this is not exactly what I meant

first of all I am making a new part in assembly, so surface of assembly subcomponent will be a border for my extrusion

can't project geometry on "blank" part while doing this in assembly mode

see screenshot

[marcin.blaszczyk]

attached files would be more useful

try to project spline to down to bottom of rectangle

Have you installed all Service Packs and Updates for your version of Inventor?

There are holes in your "capping" face, you will need to create stitched surface to close these

or

if you have Inventor Professional you could use the mold Tooling environment to to this for you.

what do you mean by capping face?.... may I ask for screenshot?

by the way, is it feasible what I want to do ?

[JDMather · Accepted solution]

Here is one technique.  (there are many other techniques - this might actually be the hardest)

These are the "capping" surfaces or "shut-offs" I needed to limit the extrusion.

thanks, this is it

never used stitch before

[JDMather]

Are you sure you really understand what I did (Copy Object)?

I don't think most people would be able to follow this technique first time around without a bunch of questions.

[marcin.blaszczyk]

yeah... after few experiments I am confused...

how did you get "composite" operation in Stitch ? couldn't create it on my own

how to stitch surfaces in attached file to create one common surface?...

"Stitch" doesn't "unite" anything here...

[JDMather · Accepted solution]

There is nothing to Stitch in your 0.ipt file.

In the original assembly -

right click adesk_2 and select Edit.

You are now editing adesk_2 in the context of an assembly of components - so you can use the other components.

Select the Copy Object command and change the Selection tool to Face.

Select the faces you need from adesk_1 to be copied into adesk_2 to cap your extrusion.

(you might now turn off visibility of adesk_1 to make the rest of the problem more clear)

You have 3 openings in your Copy Object composite surface that you need to close.

Use the Patch command to close these openings and then Stitch the Patches to the Composite.

You now have a surface body (copied from other part geometry)  that will fully cap your extrusion.

If you change the adesk_1 geometry (within logic) the adesk_2 geometry will associatively update.

ufff... yes - this is it. thnx
