Hypermesh 10.0 实例教程

In this tutorial, you will learn how to:

Create a circle, arc, line, and tangent lines Duplicate and translate lines Edit lines by splitting and displaying their IDs Delete redundant arcs and lines Duplicate and reflect an arc Create a surface square and two parallel lines on an X-Y plane Create fillet between two lines
