Hi Vignesh, Yes, "Surface Projection" tool should help you to place the antenna on a surface of a human body model.

Thanks a lot

Hi Tomasz, I don't think the access violation error has anything to do with "protected models". I think this is a bug that should be reported to the support. What version of Sim4Life are you using? did you cut the "posable" Jeduk, or did you first "Clone As Static" did you cut using the Python API, or in the GUI? if you save the model as .smash or export as .sab/.sat file, is a file written? Can you load it? what other types of entities are in the model? what happens if you copy the model entities and paste them in a different instance of Sim4Life?

Thanks for your useful suggestion! The problem I met was that the patch partically inserted into the human head, not on the surface, shown as a more clear figure below.Both gaps and overlaps exist between the projected cylinder and the skin. [image: 1652666210989-2e90feb6-bff3-43c1-99e9-4f56d3b70d96-image.png] I have remeshed the human skin and the patch, to make the voxel sizes approximated match, and it worked out! Hope this will be helpful to others with similar problem, the mesh is the crucial role.

@bryn Thank you very much.I had succeeded.

Only by snapping to objects. One strategy can be to use planar cuts to snap inside solids/surfaces

Thanks @ofli and @bryn! Yes, that's what I'm doing now, I just create them in multiple segments.

Dear Andrei, Could you please check that you have enough disk space? the error message specifies: "No space left on device". Best, Melina

@mkn the feature is available in v6.2 (or even v6.0). You select the (triangle mesh) entities to project and then the target entity (last), and start the Project / Surface Projection tool. While the tool is often useful, it can fail when the entities to be projected are nearly as large as the target surface. It usually also helps to ensure the target surface is non-manifold (Mesh Doctor -> Make Manifold) and has no degenerate triangles (Mesh Doctor -> Create Degenerate Patch -> Local remeshing of patch(es)).

I think the error "didn't manage to link up hole" usually occurs when the two objects (involved in the boolean operation) have nearly parallel touching surfaces. You could try: (always first make sure surfaces are manifold) make the cylinder overlap more with (deeper in to) the skin

Thank you @bryn! I will adapt this to my needs.

I agree that it is unintuitive that the Spline tool stops when it snaps to a vertex. I will create a bug report. There are tools that may help you: Wire Tools / Routings Tool Box / Approximate Wire Wire Tools / Fit Spline The Approximate Wire tool allows you to specify the number of handles you want. It creates a parametric spline with handles (if Parametrize=True), so you can also edit it interactively by moving the handles. I guess you can also create a spline using a list of points using the Python API.

I guess you have different options, in order of complexity stretch the whole model (it is 2.5D I think?) if there is something in the center that should not be stretched (electrodes?), you could cut the model (all entities) in three parts: bottom, center and top. you could stretch the top/bottom and then boolean unite them with the center. you could select the faces e.g. at the top (sub-picker) and offset them. you have to do this separately for each region. to specify the exact extrusion length, you can start pulling the arrow and then press the space key to type the offset/extrusion length (see attached gif)[image: 1633937557311-extrude.gif]

@montanaro Works like a charm, thank you!!

Thanks for the answer. I thought there was a way since the VIP models handle this so well, but Python should work as well. Or is there a way to to sort the priorities by entitiy name?
