￼If you set up your elevations using section viewports or a viewport from the front you will get this heavy red border. It means that the viewport needs to be updated. ￼To update the viewport, click on the update button on the Object Info Palette. What if your elevation looks like this, but you don’t want it sketchy?
￼On the Object Info Palette click on the button for the Render settingS.
This will open the Hidden Line Render Settings.
If there is a tick on the Sketch Hidden Line results then click on it to turn it off.
If the tick is not on, but your elevation is still rendered you will have to go back the 3D Model layer and check the Document Default sketch style…
Click on the OK Button.
￼Update your elevation viewport by clicking on the update button on the Object Info Palette.
Now you have hard line elevations.
