Exact positioning of objects with construction planes
1.) Drawing in the orthogonal views
2.) Revolve surfaces
3.) Extrude surfaces
4.) Planar surfaces
1.) To explain the function of construction planes
2.) Positioning of construction planes on objects
3.) Positioning of objects using absolute coordinates
2.) Rotation of the middle object
3.) Create construction plane
4.) Confirm set construction plane - create a circle
In the information window you can change the size of the circle - diameter: 5mm.
With construction planes you can choose other planes, with the toggle function you can switch between the main coordinate system and the plane. A plane can be picked and deleted. If you delete the object on which the plane is referenced, the plane will also be deleted.
5.) Extrude a circle along a rail curve
6.) Rebuild the railcurve
7.) Positioning of construction planes
A second way to position a construction plane is to snap it on a plane. You create at the end of the extrude a surface with planar surface. To position the construction plane in the center of the surface, you have to increase the patch precision to 4 patches. Press the CMD button and snap at the intersection point.
So the construction plane is in the same area as the surface.
