Go to the trim with lines sub-panel.Step 6: Split the solid geometry using a cut line.(注意利用切换视图工具,是用中键确定)Step 7: Merge solids together.(合并之后不再有分割线)Step 8: Split the solid geometry with a user-defined plane.(只要三点确定一平面就行)4. Set the plane selector to N1, N2, N3.5. With N1 active, press and hold the left mouse button, and move the mouse cursor over one of the two edges shown in the following image.The edge should highlight.Step 9: Split the solid geometry with a swept line.(选择一个实体,选择扫掠线,选择轴,那扫掠线就沿着轴向切割实体)Step 10: Split the solid geometry with a principal plane.(z轴确定XY 平面,随便确定一基点就确定了平面的位置)3. Switch the plane selector from N1, N2, N3 to z-axis.Step 11: Split the solid geometry by creating surfaces inside the solids.(需要到surfaces先创建一个曲面,注意不要勾选自动,否则难选上线,再回到实体编辑选择刚创建的面)From the Geom page, go to surfacesGo to the spline/filler sub-panel.Deactivate auto create(free edge only) and keep tangency options Select the five lines shown in the following image:Step 12: Suppress extraneous edges on the part.(压缩冒出来的边) Enter the edge edit panel.Go to the (un)suppress sub-panel.Select lines >> by geoms.(因为之前创建编辑过的线有些可能冒出来了,所以要压缩)With the solids entity selector active, select the four solids shown in the following image.(创建实体的八种方法)Geometry and Mesh Editing Using the Quick Edit Panel - HM-2070select the 2D page, then select automeshVerify that the size and bias sub-panel is selected.Verify that elements to surf comp is selected.(注意选择的面板,网格大小设为0.1)Step 2: Simplify the geometry by removing unnecessary holes.1. From the main menu, select the Geom page, and click quick edit..2 For unsplit surf:, activate line(s).(不分割曲面面板,将不需要的孔去除,用填充的话会有共享边出现,而且网格质量不好)Step 3: Modify geometry around remaining small holesFor the split surf-line function, activate node.(分割小孔的时候,先把周围修好,再修内部)Step 4: Trim a washer layer into the surface around each of the four holes. In the offset value field next to washer split, enter 0.05.(偏移值越大,垫片越大)(调整密度,先调外部垫片再调内部,最后调周围)Step 5: Adjust the mesh around the large holes on the side surfaces. Use the split surf-line(可以用其他面板生成线辅助,然后再调整密度)这里可以不调,先修剪好,然后再退到auto mesh进行编辑,可以改类型,调的更好Step 7: Adjust the mesh on the mounting flange.split surf-line adjust density(对于那些交叉的调不了的网格,可以用faces edit中的untrim调试)交叉的也可以用quick edit中的split surf-nod 来调Creating 1-D Elements - HM-3000Step 2: Create 1-D bar elements.select the 1D page, then select barsGo to the bar2 sub-panel.3.
