1 矩形阵列矩形阵列 例子 例子 1 新建一个新建一个 LED 光源或者其他 作为待阵列元件光源或者其他 作为待阵列元件 2 先定好视图 选择阵列平面先定好视图 选择阵列平面 3 根据图中步骤 做矩形阵列 根据图中步骤 做矩形阵列 4 参考软件参考软件 help 帮助文件 帮助文件 输入命令输入命令 rectArray xyz 空格空格 0 0 0 5 xyz 空格空格 5 0 0 4 xyz 空格空格 0 10 0 即 即 rectArray xyz 基点坐标值基点坐标值 x 方向阵列个数方向阵列个数 xyz X 方向阵列距离 方向阵列距离 0 0 Y 方向阵列个数方向阵列个数 xyz 0 Y 方向阵列距离 方向阵列距离 0 回车即可得到矩形阵列 回车即可得到矩形阵列 将原来的元件删除 即为最终结果 将原来的元件删除 即为最终结果 1 圆形阵列圆形阵列 1 选中元件 要选定好视图选中元件 要选定好视图 X Y 平面 再点击平面 再点击 阵列 不然出错 如倾斜 阵列 不然出错 如倾斜 出错的阵列 出错的阵列 2 输入命令输入命令 CircArray xyz 0 0 0 5 xyz 20 0 0 3 得到如下结果得到如下结果 注意 注意 LT 自带的自带的 LED 库的库的 LED 模型坐标原点和模型坐标原点和 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 标不匹配的问题 RectArray XYZ 0 25 50 30 XYZ 8 0 50 1 xyz 0 25 50 LightTools User Group Meetings Submit Your Topic Ideas You have an opportunity to help determine the topics during the annual LightTools User 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 support or join ourLightTools Group on LinkedIn to submit your ideas there We look forward to hearing them LightTools Tip Selecting Objects by Type LightTools 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 complex object 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 sphere b Select the LED group multi select using CTRL or SHIFT Command CircArray XYZ 0 0 0 1 XYZ 100 0 0 36 In 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 LED b You can use Tools Utility Library Miscellaneous Data Access Helper utility Enter 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
