Extrusion Problem

[Anonymous]

Having a major nightmare trying to extrude a sketch through a solid wing section. Sketch contstructed through rectangular pattern. I want to extrude the 'diamond' shaped profiles all the way through the body. 

I drew a box on the same sketch round the diamon profiles so as to select that, then select 'intersect' to select the inverse of this  ( ie the diamonds), select distance 'all' and set the correct direction and an error comes back a while later saying the 'operation produced no meaningful results'. If anyone could help shed some light on this problem or what is wrong with the model that would be a massive help.

The image below shows the same pattern extruded in the x direction, I'm trying to do the same again through the y direction.

Unfortunately the part is too big to attach.

Thanks in advance,

Hi David. Why do you need to create such a complicated pattern? You could do this using a mesh appearance style and the model would be much easier to deal with...

yes.. what the heck are you trying to do? 

just apply diamond tread to a wing?

Let us know your ultimate goal or a sample of what you are trying to duplicate and we can offer other potential solutions..

Mercy please!  

I am trying to create a 3D mesh that looks something like this

Except instead of triangular based 'pyramids', square based pyramids. There must be a simpler way surely!

Many thanks for all your advice again.

In general most would suggest patterning the feature (just sketch one row of diamonds then extrude then pattern that).. not patterning in a sketch..

You might have better luck with that.. 

But in general again.. very complex patterns in Inventor will bring it to its knees... Heck just create a flat plate and pattern a couple hundred holes and watch performance fall off drastically.. 

You should be able to zip the file and post it also or upload it to your A360 drive or similar (dropbox/google drive,etc)..

Or in this case, pattern the pyramid as a part.
