lighttools阵列.doc

1/矩形阵列例子：(1) 新建一个LED光源或者其他，作为待阵列元件;(2) 先定好视图，选择阵列平面(3) 根据图中步骤，做矩形阵列；(4) 参考软件help帮助文件，输入命令rectArray xyz(空格)0,0,0 5 xyz(空格) 5,0,0 4 xyz(空格) 0,10,0即：rectArray xyz 基点坐标值x方向阵列个数-xyz （X方向阵列距离，0,0） Y方向阵列个数xyz （0，Y方向阵列距离，0）回车即可得到矩形阵列。将原来的元件删除，即为最终结果。1、 圆形阵列（1） 选中元件，要选定好视图X-Y平面，再点击阵列，不然出错，如倾斜。出错的阵列。（2） 输入命令CircArray xyz 0,0,0 5 xyz 20,0,0 3得到如下结果注意。LT自带的LED库的LED模型坐标原点和LT的坐标系有些不匹配，所以阵列之后会出现坐标不匹配的问题。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 LightToolsUser Group meetings.What topics would you like to see discussed? What features in LightTools would you like to know more about? How could we help you be more productive in LightTools?We welcome all ideas, and will take those into consideration as we plan for the user group meetings. Help us make the user group a truly worthwhile event for you. LightTools User Groups are currently planned for September 2016, to be held in Sunnyvale, CA, and Marlborough, MA.Send your brilliant topic ideas tolighttools_, or join ourLightTools Group on LinkedInto submit your ideas there. We look forward to hearing them!LightTools 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 reference 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 complex objects that do not have a desirable reference point for selection. By selecting the dummy reference first, and then selecting the complexobject(s),we can use our reference object as the selection point for commands like Copy, Move, Rectangular/Circular Array, etc. One undesirable 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 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.We 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 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 commands. 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 t
