proe精度修改(国外英文资料) The default accuracy of PROE is 0.0012, but it is noted that its unit is INCH, not MM. The problem is when we set the PROE unit as MM, the accuracy is also changed to 0.0012MM? When we do PART, often prompted: please MOLD CHECK, Found the problem. Of course, PART can go on. But sometimes its difficult to work in the back. For example, splitting and converting to IGES documents will Have the arrancar produced. It is said that when PROE took into account the computers ability to achieve the accuracy of 0.0012INCH, it is still not adjusted now, PROE The accuracy in CADCAM is relatively low, can you publish it? Accuracy of parts In Pro/ENGINEER, you can use the Accuracy command to modify the accuracy of a part or component. The accuracy of a part is relative to the size of a part Value, valid value range from 0.01 to 0.0001, default value is 0.0012. Note that when you increase the accuracy of parts (reduce the relative accuracy of the value), The parts will grow longer in life. You can modify the configuration file option accuracy_lower_bound to modify the lower limit of the relative precision value, and the effective lower limit is 1.0000e-6 ~! 1.0000e-4. The accuracy of the part is less than the ratio of the minimum edge of the part to the longest side of the cuboid of the containing part. Use default unless otherwise necessary You can set the precision. In the following cases, you may need to change the accuracy of the parts: Add a very small feature to a large part. When two parts are intersected (fused or cut) to generate new parts. Two source parts to be compatible, they must have the same Absolute accuracy. To use the same absolute accuracy, we can estimate the size of the two parts and multiply them at their respective relative precision values, if the results differ The relative accuracy of the parts can be changed until the result is the same. For example, the size of a small part is 100, the relative accuracy is 0.01, and the product (absolu
