When working with elements like cladding plates, balustrade infills, decorative panels, and chequer plates, the approach to modelling them differs significantly from that used for standard structural plates. Ensuring accuracy in these cases hinges on a thorough understanding of working points and the rotation property, which are essential for ensuring the correct orientation of the visible side when generating drawings or DXF files.
Understanding the Critical Role of Working Points
It might seem simple to assume that these sheets can be flipped or rotated as needed after they are cut. However, this is a common misconception that can lead to significant errors during fabrication. The key to avoiding such issues lies in setting up the working points correctly, particularly when dealing with intricate designs or surface finishes.
The Importance of Proper Rotation
Take a stair panel, for example. If the panel features any patterns or surface differences, the working point must run in the direction from left to right when facing the stair panel. Additionally, the rotation must be set to either “top” or “front”—never “bottom” or “back.” This ensures that the visible side of the panel is correctly positioned.
Symmetry Doesn’t Eliminate the Need for Attention
Even in cases where the pattern is symmetrical or there appears to be no pattern at all, the orientation of the face of the sheet is crucial. It’s easy to think that since the machine will cut the plate according to the DXF file, it doesn’t matter how the drawing is flipped or rotated. However, this is where problems can arise.
Avoiding Aesthetic Imperfections
During the cutting process, the machine can leave minor marks on the material. These marks are typically left on the non-visible side of the sheet. Therefore, it’s critical to feed the sheet into the machine with the correct side facing outwards. If not, the marks could end up on the visible side, compromising the aesthetics of the final product.
Conclusion: Precision is Key to Quality
Proper modelling and careful consideration of working points and rotation properties are essential when dealing with cladding plates, balustrade infills, decorative panels, and chequer plates. By ensuring the visible side is correctly oriented from the start, you can avoid costly mistakes and ensure a high-quality finish.
