The main purpose of this tutorial is to show some basic use of datum plane feature in Creo Elements pro formally Pro Engineer. IN my upcoming tutorial I might use them.
Start your creo element and make a new solid part. After getting into main window click at the datum plane icon. This will open a new box asking you to select the reference. So click at front plane. To position our datum plane we need to make some offset distance so set the translation value to 70 and prefer the new plane lie behind the front plane and click ok.
Now select the front plane again and click at sketch button. in sketching window make a section as shown in fig using line and arc tool. First make a line of length 100 that is symmetrical about vertical-axis.now in arc tool menu select the center and end arc. First you have to specify the center of arc, for this just click at the middle of line than click at either end then click at other end. This will make the section like in fig. after this click at done button.
In sketching window use line tool and concentric arc tool to make the sketch as shown in fig below. First draw a line at specified distance from above reference and then select the co-centric arc tool. Click at one end of line you sketched and then click at other end keeping the arc section above.
Now we are going to draw a datum plane inclined to front plan. Click at datum plan icon and then click at top plane, for reference, make it offset up to 50. Now press and hold ctrl key and select the lower outer edge of the solid part. In following fig the mouse curser is highlighting the edge that have to be selected. it will make a plane that will be at some angle w.r.t front plane. Now just rotate the plane to make it according to fig and click ok.
