** Severe ** CheckConvexity: Surface=“surface-name” is non-planar

hi all
i front of with these eror for run energy simulatuin component
please help me

  1. The simulation has not run correctly because of this severe error:
    ** Severe ** CheckConvexity: Surface=“SHDSRF_0_0_A067A297-D570-444E-A2EC-48D5AF14BAC8_0” is non-planar.
  2. The simulation has not run correctly because of this severe error:
    ** Severe ** CheckConvexity: Surface=“SHDSRF_1_0_E3C29264-F7D6-4010-A4EB-44FF1DCCA43E_0” is non-planar.
  3. The simulation has not run correctly because of this severe error:
    ** Severe ** CheckConvexity: Surface=“SHDSRF_2_0_E3CA0D68-5742-44E7-9FA7-CF56641EE75B_0” is non-planar.

Looks like you have a non-planar face which Honeybee has failed to automatically convert it to planar faces. You can use Grasshopper to break it down into planar faces before creating your energy model.

I did not understand what you meant
Can I send you the file?

Please help me
i need to help you

You can upload a clean model here to replicate the problem. See here for best practices on how to share your model: https://discourse.ladybug.tools/faq

thanks
but im trust level 0
and i connot upload file
how i can sending file for you?

Hi -

You will quickly reach trust level 1 if you spend some time reading a few threads here. You could, for example, search to check if your question was answered in an earlier post. That might be all that it takes.

Hi,
my simulation gives the same severe error as @hakan .
I checked that the surfaces were planar with GH’s “isPlanar” component and all the surfaces turn out to be planar. I don’t understand what caused the error.

Maybe I didn’t understand what @mostapha means by:

I attach my GH file and hope you can help me. Thank you so much.

I have the same problem

Hi Sandra -

You’ll have to upload your gh file…

Hi,

I had similar issues with my model.
Most of the time this can be solved by changing the units tolerance in Rhino or by rebuilding / recreating of the problematic surfaces. One tip - use as simple as posible Rhino comands for surfaces like PlanarSrf, Loft, Sweep 1 rail, and always Rebuild the lines first and then create surface out of them.
