Edges Set(线条分类)
(1)选择不同的分组并给每个Edge Set选择线 (2)输入length值
4
选择单位
Don’t modify the units as it won’t change the units of your model
After loading step or stl files, MeshCAST will ask you to set the units

选择单位
In case you need to change (not convert) the units of your model, select the following menu

几何的检查

Input
Surface mesh • ProCAST • Patran • Ideas • Aries Solid mesh • ProCAST • Patran • Iห้องสมุดไป่ตู้eas
• Mesh the surface • Check mesh • Adapt the mesh • Write prefix.sm file • Mesh the solid • Check mesh quality • Adapt the mesh • Smooth • Optimise • Write prefix.mesh file • Visualise the mesh • Bad elements • Group/ungroup domains • Extract surface mesh

Merging
In IGS format there are often several doubled edges (blue edges). -to fix it select all cracks using the logical expression: edge:surf < 2
-push auto merge and put there the reading tolerance Tolerance-1 is the gap tolerance between the edges Tolerance-2 is the length tolerance between the edges
-按下 “Make one Edge”
14
Add Edges
- 1)Select edge (selected edge is red)
-2)Push identify -3)to see, how many surfaces belong to this edge -4)display
