Lattice tool wont work as expected

Hello Creo users,

We are trying the new lattice tool and it doesn't work as expected.

Unfortunately we are not able to generate something 😞

The final output ist a minimal surface body deformed and not even attached to the part.

 

Before:

After:

It does not at all work like in this video here:

Does anyone has an idea why this fails?

 

regards

There are three new formula-driven cell types: * Gyroid * Primitive * Diamond Using these cell types, you can create self-supported lattice geometry for additive manufacturing. Variable density is also supported. This minimizes the support structures that are required for 3D printed parts ...

Hi,

please do following steps:

  • upload your model
  • show what surfaces are selected
  • show lattice size and other numerical parameters

Hi,

thank you for your answer.

 

What surfaces do i select:

First I select the inner surfaces like so:

surface_1.pngThen I select the outer surfaces normal to X-direction on both sides (in the picture one of them is highlighted)

surface_2.png

Final it looks like this:

surface_3.png

Other lattice types work well with this surface selection.

See here:

If I switch to e.g. a Gyroid the cell moves to my initial coordinate system regardless of my selection of orientation.

The following parameters are used:

Does anyone have an ideal to overcome this bug?

Re: Lattice tool wont work as expected

Hi,

upload your model.

Re: Lattice tool wont work as expected

Also I suggest you to show the problem to PTC Support.

No ideas?

 

I am not allowed to upload any files from our systems 😞

Hi,

if you cannot upload the model, then (I hope) you can attach picture of Extrude section showing its shape and dimensions. Also you can publish the depth of Extrude feature. This information enables me to create a copy of your model. What do you think ?

Yes sure,

The thickness is 50mm. All dimensions in mm.

literally no shape works.

Thank you for helping me!

Re: Lattice tool wont work as expected

Hi,

I have to say that I am not lattice expert.

1.] I created closed quilt representing area you want to fill.

2.] I selected the quilt as Lattice volume region

3.] I finished lattice feature
