Reducing triangles
Using the optional Triangle Reduction function the number of triangles in an STL
files can be reduced to minimise the amount of calculation required in the PSW. It is
possible to reduce triangles on the entire part or only on a selected part. Triangle
reduction is recommended for the following parts:
➢ Scanned parts
➢ Parts with a large number of small holes (e.g. shower head)
➢ Parts with more than 30000 triangles.
The number of triangles can be seen on the Part Pages menu, Part information
tab, in the Mesh info group box.
1. Select component.
2. On the Triangle Reduction tab click the Triangle Reduction button.
3. On the Global tab enter the following default values recommended by EOS:
• Smallest detail: 0.02 mm
• Max. Angle: 5 °
• Number of Iterations
This value defines how often the program runs through the calculations.
A triangle reduction on objects with a very irregular surface is not to be
recommended. If the tolerance and angle are excessive, significant part
information can be lost.
