# Solid Combine
Using the Solid Blend function, you can quickly create intersecting sections of two cross-sectional stretches.
1. How to use:
- Click to enable the Entity Blending command.
Pick up Outline 1 and Outline 2
Check the Outline 1 direction and Outline 2 direction as needed
Click Apply/OK to finish creating.
2. Outline directions
The contour direction is not required. If it is not checked, the direction is the normal of the contour line by default. After being checked, the direction pickup box appears, and the contour projection direction can be picked up.
When the selected profile does not have a default normal, this box should be checked automatically, and unchecking it is prohibited.
