For example:\r\n\r\n``` python\r\nfrom solid import cube, scad_render_to_file\r\nfrom solid.utils import right\r\nfrom solid.customizer import CustomizerSliderFloat\r\nobject_count = CustomizerSlider('objects', 2, 1, 10, step=1)\r\nside = 2\r\nobjs = [right(2*i*side)(cube(side)) for i in range(object_count)] # we want this to use a reactive slider value but it can't :-/\r\nall_objs = union()(objs)\r\nscad_render_to_file(all_objs, 'customizer_fail.scad')\r\n\r\n```\r\n\r\nThis will create an OpenSCAD file with a slider, `objects` from 1 to 10. But, because the list comprehension (`objs = [right(...]`) happens only in Python code, the SCAD file will only use the initial value of the slider no matter how a user changes the slider in OpenSCAD. \r\n\r\nIf we want a row of cubes that reacts to the OpenSCAD slider, we need to run the object connection loop in OpenSCAD itself.  One way to do this would be a dedicated `scad_loop()` function we could add. But we might also add a `scad_inline()` function that would just paste an OpenSCAD string directly into the output `.scad` file without translating at all. That should make us able to use Customizer values anywhere, however we like. \r\n\r\nProposed fix: \r\n``` python\r\nfrom solid import cube, scad_render_to_file, scad_inline\r\nfrom solid.utils import right\r\nfrom solid.customizer import CustomizerSliderFloat\r\nobject_count = CustomizerSlider('objects', 2, 1, 10, step=1)\r\nside = 2\r\nobjs = scad_inline('''\r\nfor (i = [1:objects]){\r\n    translate([2*i*side,0,0]){\r\n        cube(side);\r\n    }\r\n}\r\n''')\r\n\r\nall_objs = union()(objs)\r\nscad_render_to_file(all_objs, 'customizer_fail.scad')\r\n\r\n```\r\n\r\nI'm not sure how I should build this yet, but I don't think it should take *too* much work\r\n\r\n\r\n","author":{"url":"https://github.com/etjones","@type":"Person","name":"etjones"},"datePublished":"2021-05-30T23:34:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/178/SolidPython/issues/178"}
