Transverse-momentum-dependent parton distributions (TMDs) are now recognized as crucial ingredients for a complete understanding of the dynamics of confined partons especially in the non-perturbative regime of QCD. They allow for a 3-dimensional description of the nucleon in momentum space, and could provide insights into the yet unmeasured quark orbital angular momentum. At CLAS several TMDs are explored in Fourier analysis of azimuthal asymmetries measured in semi-inclusive DIS. An overview of the main CLAS results as well as selected CLAS12 projected results is presented.
