Surface creation

- [Instructor] So, I parsed out the data that I want…and by activating that little region off of the STL,…I now can go into a tool called Basic Surface Recognition…and I'm going to pick the surface and hit Apply.…What I want you to notice…is it's currently set to Automatic…and with that, it wants to create this big, giant cylinder.…The reason why it wants to create that big, giant cylinder…is it's picking up some potential defects…from the manufactured part.…

Remember, I scanned this in…and it's a plastic part.…It's been through manufacturing,…it may have been used,…so as the part is aged,…it's going to create some deformation in the part…and with age, plastic tends to bend and twist.…So, the system is picking that up…and what I want to do is I want to tell it that it's planar.…Select Apply, let me go down to the bottom…of the tree, you'll see it hasn't created anything yet.…So, it puts out this surface…and it allows me to increase the size,…grabbing those handles, I can decrease as well…and once I have that surface…
