Edit Mesh Fill & Solid

I am selecting vertices and using the Fill feature to build my architecture etc. but these faces are allowing me to move through them. When using the Mesh / Fill in Edit mode, is there a way I can make the newly created faces solid?



You must check in Face select mode ( F key) if the face have the Collision button
enabled in the Texture face panel
Or when the object is finnished select the desired faces, pess the collision button
and the Copy Draw button to assign collision to all the selected faces.
