20、怎样使用trail.txt.?
答:用写字板打开trail.txt,将里面你要恢复到的地方之后的操作删除掉后存盘用PROE打开即可。作者: lktlxm 时间: 2005-9-5 15:23
21、怎样画椭圆?
答:在20版中会比较麻烦,要用到高级草绘中的conic(圆锥曲线)来画。这个功能在练习中有一个会用到。
1) in drawing
pro/detail/sketch/other/ellipse
2) in sketch
you cann't create a ellipse directly, but you can sketch four conic(its orth equal 0.41) to form a ellipse.
3) in part
pro/feature/create/datum/curve/from equation(need create a coord sys first
23、在逆向工程方面,UG与CDRS相比,哪个更占优势?
答:UG在FREE FORM FEATURE中有由点云直接生成曲面的功能,另外,UG16中另有专门进行逆向工程的模块。我认为搞逆向工程比较好的还是SURFACER,在IDEAS7中就带有SURFACER9,IDEAS8中带SURFACER10。说实话,UG我不熟。不能给您一个对比。不过就UG的定向来看,应该是和PRO/E同功能的软件,可能不适合做逆向。而CDRS是专业做曲面的,虽然它不是主推逆向工程,但是我用的感觉是用CDRS做逆向可以比PRO/E快至少3倍。
24、自己做的JPG图无法在PRO/E下使用,使用时要不自动推出,要不提示文件不在贴图文件搜索目录里,但同目录下有的JPG文件可用,这是为什么?
答:我做过自己的JPG,是没有问题的,不过PRO/E有时候很怪。我想你可以试试减少IPG文件的大小可不可以,如果实在不行就干脆把文件拷到它可以接受的目录下。
25、In drawing mode, when I try not to display tangent edge line in standard 2-D view, they dispeared in whole drawing, So Can you tell me how to erase tangent edge line in 2-D view drawing but the tangent edge line display in 3-D view ?
答:THE COMMAND IS VIEW/DISP MODE/VIEW DISP THEN SELECT THE VIEW。First Select View-Disp Mode-View Disp, then select the view,choose No Disp Tan.
38.如果一个产品从外观造型开始到结构设计.我的程序是这样的:
a. 先用autocad排列大致的元器件装配空间位置。
b. 再用photoshp or coreldraw 绘制平面效果图。
c. 确定后再在autocad中调整尺寸及零件分割。
d.到pro-e中进行三维造型验证装配及外观。
你们是怎么做的呢?
答:您的方法如果用来做机械设计还勉强可以应付,如果用来做家电等就不行了。
我的方法如下:
1.外观造型用CDRS做,这里面有两种类型:正向设计和逆向设计。用CDRS来做可以很方便的和PRO/E交流数据、修改数据。不过CDRS主要设计的还是曲面,如果您的产品是某种机械就不是很合适了。
2.结构设计和装配用PRO/E做。其实做结构也是PRO/E的强项。
3.工程分析用PRO/MECHANICA做。可以进行静力学和动态分析,疲劳分析等,可以最大限度的优化您的设计,保证您的产品没有设计上的问题。
4.如果需要模具的话还可以用PRO/E进行模具设计和数控编程。
另外PRO/E的TOP-DOWN设计比较适宜做机械结构的设计,您可以用它来进行从上到下的设计。
49.I am a new comer of Pro/engineering. But I am a dilligent guy. Thanks for your help. How to create a cube?
答:That's easy.
1.Feature-Create-Datum-Plane-Default
2.Feature-Create-Protrusion-extrude solid-done
3.Select sketch plane,one side-done
4.make a 20X30 rectangle,after regenerate,press done
5.select blind,then enter depth(50)
6.press OK
51.为什么有的文件不能redefine/midify?怎样操作才能恢复正常功能呢?
答:看一下你的提示是不是"CAN NOT REDEFINE READONLY FEATURE",如果是的话可能是被设为只读了,可以在READ ONLY菜单下用CLEAN清除,就可以编辑了。
52.I had a trouble, which is when I merge more than two surface at same time,after finished the manipulation,it always megered the primary surface and the last one I selected.If I do it one by one,it'd waste my precious time.So I beg you would help me to solve this problem.
答:You can not merge more the 2 surface at same time.
69、drawing中出现如下警示语句:cannot delete a view with "children";select again.怎么办?"children"何意?我重新选过几次,没用。是否这个view就delete不了?
答:你删除的视图有子视图,即你要删除的视图被其他视图参考,你要想删除它必须先删除子图。
72、请问怎样画局部剖视图?
答:views---add views---projcection--full view--section---no scale---done local---total xsec---done then like draw a section then pick a center point and draw a spline. try it . and you'd better buy a book. it is basic.
73、在绘制SKETCH时的圆弧连接总是REGENRATE FAIL,因为圆弧连接处有一点瑕疵
答:the qestion is fuzzy.do you have file. email to me vagrant_lyc@sina.com you can use intent manager to draw a shape like what you want. then use contstain and modify the value. the other thing is that if you are a new hand, do not draw too complex draft in one step. jut step by step.
74、HOW TO IMPORT DWG OR DXF FILE TO PRO/E FOR MAKING MODEL?
答:That's possible,but you can not use it to make a 3-d model. as I know you must in sketch. and you can import dxf files. but it is very bad for complex drawing.once you constain it. there is many problem. I suggest you do not use it. you can import dwg file in format mode. but only the line can be import.it is imported as border
85、在CDRS里,从IGS输入的点能否改变它的大小?.另外,在convert里的scaffold to curve是起何作用?
答:CDRS里,从IGS输入的点只是输入线(scaffold ),你需要通过他们再做出CURVE线.在convert里的scaffold to curve是直接将scaffold 线(输入线)转为curve线。
86、我在使用CDRS中,在use the point of scaffolds to fit curves中,用了好几次,fit 功能好象不起啥作用。这是为啥?
答:use the point of scaffolds to fit curves这个功能我认为意义不大,一般是用捕捉功能直接在scaffold上做一条近似的CURVE线,然后再修改CURVE线。
