In this article we are going to explore how the feature is applied to the part to create the appropriate relief. We are also going to explain what the relief dimensions and some of the relief options means.<\/p>\n

For the circular and square reliefs their sizes\u00a0are easy to figure out. The circular relief dimension specify the radius of the relief and the square relief its side dimension. Fig. 1, shows also how the circular and square reliefs are applied when the \u201cCentered on bend lines\u201d is unchecked.
\nWhen the \u201cCentered on bend lines\u201d is not selected the outer edges of the flanges meet the center of the circular and square relief.<\/p>\n

\"Fig1\"<\/p>\n

For the obround relief, we use a \u201cslot type\u201d of cut to create the relief. Its dimensions are shown in Fig. 2 (center). Its positional cut in the flat pattern is such that the center of the inner slot arc matches the inner bend region limit of the bends. Fig. 2 (center and right)<\/p>\n

Centered on Bend Lines Option<\/strong><\/p>\n

When the option \u201cCentered on bend lines\u201d is checked, the center of the square and circular reliefs match the intersection of the bend lines Fig. 3<\/p>\n

\"Fig3.1\"<\/p>\n

For the obround relief, the bend lines intersection meets at the center of the slot.<\/p>\n

\"Fig4.1\"<\/p>\n

Ratio to Thickness Option<\/strong><\/p>\n

This option is straight forward. Assume the thickness is 1 mm, a \u201cRatio to Thickness\u201d equals to 4 will create a 4 mm per side square relief Fig.5<\/p>\n

\"Fig5.1\"<\/p>\n

For the obround relief the \u201cRatio to thickness\u201d options works in a similar manner. For a 3 width ratio, when the part is 1 mm in thickness, the width of the slot will be 3 mm. As Fig. 6 shows, when the \u201cRatio to thickness\u201d is used in a obround relief, the width ratio has more influence on the shape of the relief than the length ratio.<\/p>\n

 <\/p>\n

\"Fig6.1\"<\/p>\n

The \u201clength\u201d ratio (3.2) Fig. 7, only affects the relief within a narrow margin. At length ratio equal to 3.2 \u2013this is the minimum possible length ratio , \u2014 the relief will look like more rounded.<\/p>\n

\"Fig7.1\"<\/p>\n

Fig. 8 shows the obround relief with the \u201cCentered on bend lines\u201d and \u201cRatio to thickness\u201d options. The bend lines intersection will be at the center of the slot.<\/p>\n
