Tutorial 3: Creating Large Size Perforated Pattern

3. Generating the desired perforated pattern based on effective size

To generate the perforated metal pattern for this large façade is always about the designer‘s idea and favor. However, there are some useful tips that will be useful:

When generating large size (e.g. for façade building) of perforated metal pattern, the more punch tool we use the better the perforated pattern reflects the original image. In this tutorial, 10 round punch tools are used to generate the perforation design.
Always justify the perforated pattern design by using material pattern viewing on Image2Punch Pro as this viewing will give the closer appearance of the perforated panel after they have been manufactured.
The image size and the perforated pattern panel size should be proportional. For example, if the perforated metal sheet is generated onto 1200mm X 2400mm the image size should be in the proportional scale of those sizes. ( e.g. 600px X 1200px or 300px X 600px).
In the case that you are not able to make the image proportion to the perforated pattern sheet, you can always use stretching mode as this is used in this tutorial to generate the final result of perforated pattern design.
The minimum punch hole should be equal or larger than material thickness. (this is true for aluminium, mild steel and galvanize). However, for stainless steel, the minimum punch hole should be as twice as the material thickness or even larger than that.
The minimum gap between holes should be equal or larger than material thickness.
