[SOLVED] Using SOFACarving with OBJ files

[Anonymous]

Hi,

I am trying to use the SOFACarving Plugin to cut into a obj model that I have, but it gives the following error:
[WARNING] [CarvingManager(carvingManager1)] CarvingManager: modelSurface not found
I am not sure if it is me who is doing it wrong or the plugin does not work with obj file files.

Here is my scn (it is a modified version of the example in the SOFACarving Plugin):

<?xml version="1.0" ?>
<Node name="root" dt="0.05" showBoundingTree="0" gravity="0 0 0">

    </Node>

      <Point name="ParticleModel" tags="CarvingTool" contactStiffness="2" />
      <RigidMapping template="Rigid,Vec3d" name="MM->CM mapping"  input="@instrumentState"  output="@Particle" />

    </Node>

  </Node>

</Node>

Hi @fayad
SofaCarving plugin need model tool and model surface
you must give it model tool and model surface address
model tool and model surface are a collision model
for more details, please see carving manager example in plugin directory

Good Luck

Thanks, will look into that.
