constraining sketch

in making a square using a sketch can be done by three methods, 1) using 2 points, 2) using three dots, three) from the center and then determine the next two points, in the following example I use two point method.

 after making a square give constraints on both, constraint serves to maintain the logic of a model according to the type of constraint is chosen, there are various types of constraint that can be selected, to launch a constraint, click the icon on the toolbar of the available constraints

then, select the appropriate constraints, in this example I use the parallel constraint, constraint-click way to make two parallel lines, then select the type of parallel constraint on the dialog box that is available, so the two lines that have been selected to apply the logic that the two lines are always parallel.many choices of constraints, ranging from fixed, all fixed, center, etc. use the appropriate type in accordance with the desired type of constraint, if still confused what kind of constraints that are suitable for use, UGS-NX5 provides automatic constraint, just click the icon automatic constraint, then the shape that has your design will be given an appropriate constraint by itself,

as evidence that the two lines you have chosen already in the constraint, I put value on one line, dimension by selecting the icon, then select create a dimension with a click of the tips of two lines, value listed not fix yet, click on the value and change dimensions, in example become 70, you will see another line that has been in parallel constraint will be changed to 70.

Make Shaft using Sketch and Revolve

by using revolve we can make simple and complex 3D model from 2D model that have cylinder shape, like shaft, bolt, drum, pulley, fly wheel and other cylinder product.
now our project at this post is make shaft like picture below



Step to make shaft are
1. open sketch
2. make a half 2D shaft using profile
3. finish sketch , revolve the half 2D sketch model.

to begin using revolve, click in the feature toolbar, like picture below



to learn step by step of this tutorial, please refer to video below to learn make shaft using revolve feature, here i try to upload in veoh, because i think veoh video quality is better than youtube, although same times any advertisement added in video

Begining Sketch Operation, Extrude

last month i post how to make block easier using Form Feature Operation, now let's learn make more attractive block using sketch in unigraphics NX5, sketch is basic feature in UGS that we can make block, cylinder, pipe and other 3D model from 2D model. so let's try make 3D model from 2D model.
Begin Sketch using Icon
to begin sketch click the sketch icon like picture below, it usually located at feature tool bar.


to see how to use sketch, to make block, try to play this video


after clicking the icon, next step is define the plane of sketch, default plane are X -Y plane, if we clicking OK to the default value, we will make sketch plane on X - Y Plane. as see on picture below, we can choose sketch plane. direction of plane, plane option and reference. at this tutorial we use X-Y default plane.



after click OK, Sketch plane will available, at those plane we can drawing using 2D model type like line, arc, profile, circle. try using profile to make like continues line connection.

we can choose preferred snap point option, when we choose profile we also can choose basic shape, line or arc.

begin to sketch with 0,0 coordinate, click the 0,0 then bring it horizontal click other position and the closed line connection like picture below.












then after make closed connection line, right click your mouse choose OK.













EXTRUDE OPERATION
we can make 3D model using extrude operation from 2D model like sketch or line, to begin extrude operation click the extrude icon








dialog box will appear, fill the end distance value 25, then click to 2D sketch line, click OK.





3D model from extrude and sketch will appear like picture below
