We present results from our e ort to generate new simulations of slitless NIRCAM observations. This simulator fully supports both the R and C mode of NIRCAM (or any other HST or JWST slitless grism). The work shown was enabled by a new Grism Configuration format and a small Python. Combined, they provide users with easy access to the functions that are necessary to compute the transformation from direct images to dispersed images. This makes it possible to either simulate or extract spectra from grism data. We also show examples produced from a Position Angle Simulator. This software was designed to facilitate observation planning by allowing an observer to quantatively predict the amount of spectral contamination in planned observations.
