When one draws a slab or solid (in illustration or monochrome Visual Style) with the help of MicroStation solids, it gets displayed with transparency and then tries to turn off the Transparency from View Attributes, the solid’s opacity doesn’t get changed. To turn off the transparency and to avoid this issue, follow the steps below.
1. In the Search ribbon type Material Editor and click to open Material Editor dialogue box.2. In the Material editor tab, under the level which you are working, go to transparency tab and increase the opacity to 100 as shown in the image below. 3. We can see that solid becomes fully non transparent. In this way, we can adjust the opacity/transparency of solids from the Material Editor tab.
