lighttools陣列

1、1/矩形陣列例子：(1) 新建一個LED光源或者其他，作為待陣列元件;(2) 先定好視圖，選擇陣列平面(3) 根據(jù)圖中步驟，做矩形陣列；(4) 參考軟件help幫助文件，輸入命令rectArray xyz(空格)0,0,0 5 xyz(空格) 5,0,0 4 xyz(空格) 0,10,0即：rectArray xyz 基點坐標值x方向陣列個數(shù)-xyz （X方向陣列距離，0,0） Y方向陣列個數(shù)xyz （0，Y方向陣列距離，0）回車即可得到矩形陣列。將原來的元件刪除，即為最終結(jié)果。1、 圓形陣列（1） 選中元件，要選定好視圖X-Y平面，再點擊陣列，不然出錯，如傾斜。出錯的陣列。（2） 輸入命令C

2、ircArray xyz 0,0,0 5 xyz 20,0,0 3得到如下結(jié)果注意。LT自帶的LED庫的LED模型坐標原點和LT的坐標系有些不匹配，所以陣列之后會出現(xiàn)坐標不匹配的問題。RectArray XYZ 0,-25,50 30 XYZ -8,0,50 1 xyz 0,-25,50LightTools User Group Meetings - Submit Your Topic IdeasYou have an opportunity to help determine the topics during the annual LightTools® User Gr

5、ools Tip: Selecting Objects by TypeLightTools allows you to select objects using different filter types such as Solid, Primitive, Surface, etc. via the context menus in the 3D View or the System Navigator/Properties Dialog. But these selection filters do not include some object types such as referen

6、ce geometry and dummy objects.There are numerous cases where you use dummy objects to aid creation/modification of geometry in LightTools. One common example is the use of a dummy sphere (or a point/coordinate system object) as a specific reference point (also known as a tag point for selection) for

7、 complex objects that do not have a desirable reference point for selection. By selecting the dummy reference first, and then selecting the complex object(s), we can use our reference object as the selection point for commands like Copy, Move, Rectangular/Circular Array, etc. One undesirab

8、le effect of this approach is the creation of additional reference objects that can add clutter to the model. This tip highlights how to use the Data Access Helper utility to make the selection process easier for you in order to remove additional objects.Consider the case where you want to create a

9、circular array of LEDs using a base LED model, which does not have a desirable reference point for selection/arraying. By adding a dummy sphere as a reference point, we can create the array easily. The remaining issue is how to remove the additional dummy objects resulting from the array operation.W

10、e end up with the picture shown below, after generating the Circular Array.a.  Select dummy sphereb.  Select the LED group (multi-select using CTRL or SHIFT)Command: CircArray XYZ 0,0,0 1 XYZ 100,0,0 36In order to remove all the extra dummy spheres you can do the following:1. Hide all

11、 groups in the model.a.  Groups contain the source and the CAD geometry for the LEDb.  You can use Tools > Utility Library > Miscellaneous > Data Access Helper      utilityEnter “No” in the data value field and click “Set Value” button to execute the comma

12、nds. This will hide all groups and leave only dummy spheres visible in the model. 2. Use the selection tools to select all the visible dummy spheres. “Inside” or “Outside” buttons can be used to select all objects. 3. Press Delete to remove the dummy objects.4. From the Edit menu, select “Show All.” Select th
