If you box select rather than individually select then you cannot control the order they will be used. First two vectors will be the rails and the subsequent vectors will be the cross sections used in the order they are selected. Hold the Shift key and select the left side first and the right side second Still holding Shift select the cross sections individually, along the top level left to right and then along the bottom level left to rightThe order of selection is very important as it dictates the order the shapes will be used by the new Shape Editor. Picking from the part which joins top and bottom spiral. The cross sections will be applied from the centre of the top spiral down to the centre of the bottom spiral. In order the first is 1 inch high, the second 0.8 high, the third 0.6 high, the fourth 0.4 high, the fifth and sixth 0.2 high, the seventh 0.4, eighth 0.6 and final one 0.8. The boxes to the left will be the cross sections of the model. In the middle of each spiral is a circular vector. The Spirals were created from sketching vectors over a photograph of a part with the same design. The file is pre-prepared with vectors that were drawn in ArtCAM. Ann application of this idea is shown in the picture below right.
The introduction of the multi cross section 2 Rail Sweep makes this much simpler to create. All the files for this project are under the Friday presentations in 4 Adv_Modelling/Demo Files, each project has its own named sub-folder with the files for that project contained in it.ġ Creating a Rising Spiral ShapeUp until version 7 it was very hard to make a shape with a spiral that rises up in z at the same time.
The idea in this section is to show how different tools in ArtCAM can be used in combination to produce the parts you require. The techniques here will try to show a variety of different shapes, some will be individual techniques and some will be complete modelling projects.
Advanced Modelling TechniquesIntroductionThis section will deal with a variety of advanced modelling techniques to create different relief effects.
