What is the 2d Sketch Constrain Or Geometry Constrain In AutoDesk Inventor & How To Use Them ……
Working with AutoDesk Inventor, Users need to know the first step of AutoDesk Inventor. 3d part always created by the 2d sketch in AutoDesk Inventor. So users need to create the 2d sketch first. For creating the 2d sketch, there is Constrain toolbar in the inventor which allows to users to make the 2D sketch easier. Constraints play a big role to make the 2D sketch or geometry easier in the AutoDesk Inventor. Constrain also stop unwanted changes of the feature if dimensions are changed or referenced geometry is moved. Users can also add or edit constrain and dimensions for control the sketch shape and size.
Type of 2d sketch constraints in AutoDesk Inventor.
There are 12 2D constraints in AutoDesk Inventor as shown in pic-1.
pic-1
1. Coincident Constraint
Coincident constraint allows us to constrains point to other geometry in the 2d sketch.
Select the first point or curve of the first geometry and then select the second point or curve of the other geometry as shown in pic-2.
pic-2
2. Collieaner Constraint
Collieaner constraint allows us to constrain line on the same geometry.
Select the first geometry and then select the second geometry as shown in pic-3.
pic-3
3. Concentric Constraint
Concentric constraint we use to keep the center of the two circle, arc or ellipses.
Take the cursor on the first circle & click on it and then select the second circle as shown in pic-4.
pic-4
4. Fix Constraint
Fix constraint allow us to fix the geometry at the same position. There is no need to give dimensions from the axis to fix the geometry.
After giving fix constrain, geometry will look in fully constrain color as shown in pic-5.
pic-5
5. Parallel Constraint
Parallel constraint we use to make the geometry parallel to the other geometry.
Select the first geometry which needs to make the parallel to the other geometry and then select the second reference geometry as shown in pic-6.
pic-6
6. Perpendicular Constraint
Perpendicular constraint allows us to make the line perpendicular or 90 Degree to the other geometry.
Select the first line and then select the second reference line where to make the perpendicular as shown in pic-7.
pic-7
7. Horizontal Constraint
Horizontal constraint allows us to make the line horizontal to the horizontal axis.
Select the line which is at an angle to make the horizontal to the horizontal axis as shown in pic-8.
pic-8
8. Vertical Constraint
Vertical constraint allows us to make the line Vertical to the vertical axis.
Select the line which is at an angle to make the vertical to the vertical axis as shown in pic-9.
pic-9
9. Tangent Constraint
Tangent constraint allows us to make the line or circle tangent to the circle or line as shown in pic-10.
pic-10
10. Smooth Constraint
Smooth constraint allows us to make the Spline or curve to smooth as shown in pic-11.
For example, two curves or spline connected at a point. Use smooth constraint to make the connection point smooth.
pic-11
11. Symmetric Constraint
Symmetric constraint allows us to make the two line symmetric from the reference line.
First, select the two line and then select the reference line where to about symmetric the two line as shown in pic-12.
pic-12
12. Equal Constraint
Equal constraint allows us to make the Equal the circle, line, radius, arc etc.
For example, there is three or more circle drawn & want them to equal radius or diameter of all. Use equal constraint to make the same radius as shown in pic-13.
