這個軟件那里有下載的，請幫幫小弟，謝謝。

小弟是新手，請問相對于ASAP，在設(shè)計導光板方面，LT有什么優(yōu)和缺，能比較下嗎？？？謝了

請問auto-cad的網(wǎng)點怎么導入啊，還有那個autolist是一個什么樣的插件哦？

把網(wǎng)點參數(shù)寫成.TXT格式,在導光板的TEXTURE中導入就可以在LT 中得到網(wǎng)點,只是中間要有個坐標轉(zhuǎn)換,計算要精解. 5qx$=6PT  
多試幾次就可以了.

能詳細說明嗎？謝謝！

lighttools有一個插件叫DXF Tool，可以把autocad的圖檔先轉(zhuǎn)成DXF檔，然後再吃進去lighttools，也可以把lighttools的網(wǎng)點轉(zhuǎn)出成dxf檔，讓autocad讀。

Parameterize the Bumps 6

The Backlight Utility was helpful to build the backlight system quickly. However, (ug^2WG Yq  
the bumps must be parameterized in order to get the desired output distribution. 8P#jC$<  
You can do this easily using the LightTools Properties dialog box. atA:v3"  
1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, Q7-d]xJ^  
BottomSurface, and Zones. Then, select Texture, as shown in the following C_JDQByfL  
figure. 0=^A{V!m  
2.Right-click and select Properties on the shortcut menu. yxt`

The default number of bumps is 100 (10 X 10). You need to change these C=z7Gk=  
parameters to match your design. Note that LightTools allows many other oL2 a:\7  
placement options, but you will use the Bezier placement option for this +%hA6n  
example. DfNX@gbo  
5.On both the X Placement tab and Y Placement tab, change the Number of .jfkOt?2  
Bumps parameter to 300, as shown in the following figure. Click Apply after mz~aSbb|  
each change. vQ/&iAyut  
6.Click OK to close the dialog box. -8]M ,,?  
Note that the number of bumps is 300 X 300, which results in about 90,000 `f9I#B  
bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a _m+64qG_8'  
manner defined by the Bezier parameterization option. Please see Chapter 5 of G/*0*&fW  
the LightTools Core Module User’s Guide for more information. With the dsh S+d  
current parameter values, the Bezier option varies the bump spacing along the E9L)dMZSpj  
length of the light guide. The spacing in the orthogonal direction is constant. `2M`;$~ 5
