Share a case of vase parametric design and 3D printing. XGD/GGR allows me to easily design a vase with complex shape, generate multiple shapes of vases by modifying design parameters, and quickly generate 3D printing trajectory lines. Then I conduct robot trajectory planning and simulation in Delmia, and generate offline programs for 3D printing.  However, it takes me a lot of time to generate robot target points according to the trajectory line by using the relevant functions in Delmia module, which takes about 2 hours for 5000 points, and the simulation is also relatively slow, while I can complete the same operation with other software (such as Grasshopper) in about 1 minute. Delmia is very inefficient, especially when dealing with a large number of target points, and hopefully developers will take steps to optimize software performance.
