1.用工作平面对体等元素可进行任意方向的切割,先将工作平面(X-Y平面)移到要求的地方,然后进入 utility menu>plotctrls>style>hiden line option>弹出一个对话框,type of plot后的下拉框中选择section,在cutting plane is 后的下拉框选择 working plane
2.可以通过/TRLCY设置体等元素的透明度。用法如下
/TRLCY, Lab, TLEVEL, N1, N2, NINC
Specifies the level of translucency.
Lab:Apply translucency level to the items specified by the following labels: 可以应用于单元、面、体等
ELEM — Elements. Use N1, N2, NINC fields for element numbers.
AREA — Solid model areas. Use N1, N2, NINC fields for area numbers.
VOLU — Solid model volumes. Use N1, N2, NINC fields for volume numbers.
ISURF — Isosurfaces (surfaces of constant stress, etc., value). Translucency varies with result value, to a maximum of the specified translucency level.
CM — Component group. Use N1 for component name, ignore N2 and NINC.
CURVE — Filled areas under curves of line graphs. Use N1, N2, NINC fields for curve numbers.
ZCAP — If /TYPE,WN,ZCAP is the current display type, then /TRLCY,ZCAP,TLEVEL will display the model in window WN with the portion of the model in front of the section
plane displayed at the translucency level TLEVEL.
ON, OFF — Sets the specified translucency display on or off. All other fields are ignored.
TLEVEL 设置透明水平,数越大,越透明;
Translucency level: 0.0 (opaque) to 1.0 (transparent).
下面为一个“透明”及“切割”小示例:
!一个立方体和一个球相交,仅对体1即正方体进行透明显示,通过工作平面(对角面)进行“切割”显示
/PREP7
BLOCK,,1,,1,,1, !建立立方体
sphere,0,0.2,0,360 !建立一个与立方体相交的球体
wprot,0,0,-45 !旋转工作平面,做切割准备
/TRLCY,VOLU,0.8,1 !对体1使用半透明设置(可对部分体进行透明显示),0.5为透明度(Translucency level),该数越大,越透明;
/replot
/GRAPHICS,POWER
/TYPE,1,7 !通过工作平面来切片显示
/CPLANE,1
/REPLOT
/view,1,0.5,1,2 !调整视角,便于观察
/REPLOT
最终结果为改图,切面显示+透明度设置。
