How do you define a sketch Onshape?

What are some reasons that a sketch may not be fully defined?

Missing constraints to the origin. Centers of arcs aligned vertically to origin, mid-point to vertical centerline or driven dimension from origin to one side. This could also use a few mirror/symmetric constraints to cut down the number of dims as well.

How do you dimension a sketch?

To start, click on the Dimension icon on the sketch toolbar.

…

Dimension

1. Click or press the D key.
2. Select the entity (or entities between which) to dimension and the location of the dimension. The dialog opens on the placement of the dimension.
3. Enter a value and press Enter to accept the value.

How do you constrain sketches on Onshape?

With Onshape, you have many different constraints to choose from to help define your design intent. You will find the constraints in Onshape on the far right of the sketch toolbar: To add a constraint, simply select the entities you want to constrain and the constraint type.

Why is my sketch under defined?

In this tech tip we’ll answer the common question: Why is my SOLIDWORKS Sketch Pattern Under Defined? The reason is because the sketch instances can rotate. You could previously Fully Define the instances by adding a Horizontal or Vertical relation on one of the construction lines tied to the instances.

How do you make black Onshape sketches?

Best Answer. @john_smith077 , You have to give dimension for conversion from under-defined line (Blue) to fully- defined line (Black). If you do not want to give dimension then apply fix constrain to line then it will convert into black color. Currently in Onshape user can not change property of line.

How do you tell if a sketch is fully constrained?

A sketch is fully constrained when the size and position of all sketch geometry is completely defined. This is achieved using a combination of constraints and dimensions. You don’t always need to fully constrain sketches, but it is often good practice to do so.

Why are my lines Blue in Onshape?

Blue means under-constrained. Black means fully constrained.

How do you move a sketch Onshape?

To do so, first select the transform tool on the sketch toolbar.

…

StepsCopy link

1. Click .
2. Select the sketch entities you want to move.
3. Use the manipulator to drag and orient the sketch.
4. Click in space when the sketch is placed and oriented as desired.

Can you scale a sketch in Onshape?

You can scale a sketch by having only 1 dimension. That one dimension drives the scale. As soon as you add a second dim it will begin changing only the geometry affected by that dim. If you have a small sketch, i would delete the dims except 1.

What advantages do CAD sketches have over freehand sketches?

What advantages do CAD sketches have over freehand sketches? CAD sketches are easily fixed and allow for an isometric view and a multi-view perspective.
