Advanced mates (angle, width, path) in Solidworks - Dashboard Guide

Dashboard Mode - Advanced mates (angle, width, path)

Business Question

How can we use advanced mates like angle, width, and path mates in SolidWorks to control assembly movement and alignment precisely?

Sample Data: Assembly Components and Mates

Component	Mate Type	Parameters	Result
Bracket	Angle Mate	30 degrees between Bracket and Base	Bracket fixed at 30° angle
Slider	Width Mate	Slider fits between two Guide Rails	Slider centered between rails
Arm	Path Mate	Arm moves along curved path	Arm follows path smoothly
Pin	Angle Mate	Pin at 90 degrees to Plate	Pin perpendicular to Plate
Cover	Width Mate	Cover fits between two Walls	Cover aligned and constrained

Dashboard Components

  Formula: Count of mates with type Angle, Width, or Path = 5
• Bar Chart: Count of Each Mate Type
  Data: Angle=2, Width=2, Path=1
• Table: Detailed Mate Parameters and Results
  Shows Component, Mate Type, Parameters, Result columns from sample data

Interactivity

Filter by Mate Type (Angle, Width, Path) updates Bar Chart, Table, and Pie Chart to show only selected mate types. KPI Card updates total count accordingly.

Clicking a component name in the Table highlights that mate type in charts.

Self Check

Add a filter for Mate Type = 'Path'. Which components update?

• KPI Card updates to show 1 mate.
• Bar Chart shows only Path mate count.
• Table filters to show only Path mates.
• Pie Chart shows 100% Path mate.

Key Result

Dashboard shows counts and details of advanced mates (angle, width, path) used in a SolidWorks assembly.

Practice

1.

What is the main purpose of using angle mates in SolidWorks assemblies?

easy

A. To create a path for a part to follow

B. To control the rotational angle between two components

C. To lock the position of a part in all directions

D. To fix the distance between two parts

Solution

1. Step 1: Understand the function of angle mates

   Angle mates specifically control the rotational angle between two parts, allowing precise angular positioning.

2. Step 2: Compare with other mate types

   Distance mates control linear spacing, fixed mates lock all movement, and path mates guide movement along a path.

3. Final Answer:

   To control the rotational angle between two components -> Option B

4. Quick Check:

   Angle mates = control rotation [OK]

Hint: Angle mates set rotation, not distance or fixed position [OK]

Common Mistakes:

• Confusing angle mates with distance mates
• Thinking angle mates fix all movement
• Mixing path mates with angle mates

2.

Which of the following is the correct syntax to create a width mate between two faces in SolidWorks?

1. Select both faces
2. Choose Width Mate
3. Select the center plane
4. Confirm

easy

A. Select one face and one edge, then apply width mate directly

B. Select two edges, then select a reference axis to define the width mate

C. Select two faces, then select a center plane to define the width mate

D. Select two faces only, width mate applies automatically

Solution

1. Step 1: Identify the correct selection for width mate

   Width mates require selecting two faces and a center plane or axis to define the width constraint.

2. Step 2: Eliminate incorrect options

   Edges alone or one face and one edge do not define width mates properly; automatic application without center reference is incorrect.

3. Final Answer:

   Select two faces, then select a center plane to define the width mate -> Option C

4. Quick Check:

   Width mate = two faces + center plane [OK]

Hint: Width mates need two faces plus a center reference [OK]

Common Mistakes:

• Selecting edges instead of faces
• Skipping the center plane selection
• Assuming width mate applies automatically

3.

Given an assembly where a path mate is applied to a slider component along a curved edge, what will happen if the path is a closed loop?

medium

A. The slider will move continuously around the loop without stopping

B. The slider will stop at the start point and cannot move further

C. The slider will move back and forth along the path

D. The slider will detach from the path and float freely

Solution

1. Step 1: Understand path mate behavior on closed loops

   Path mates constrain movement along a defined path. If the path is closed, the component can move continuously around it.

2. Step 2: Analyze other options

   Stopping or detaching does not occur unless additional mates or limits are applied; back and forth motion requires limits or motors.

3. Final Answer:

   The slider will move continuously around the loop without stopping -> Option A

4. Quick Check:

   Closed path mate = continuous motion [OK]

Hint: Closed path means endless movement along it [OK]

Common Mistakes:

• Assuming slider stops at start point
• Thinking path mate causes back and forth by default
• Believing slider detaches without extra mates

4.

In an assembly, a user tries to apply an angle mate between two faces but receives an error. What is the most likely cause?

medium

A. The angle mate requires a reference axis which is missing

B. The faces are coincident and angle mate is redundant

C. The two faces are parallel and angle mate cannot be applied

D. The faces belong to the same part and mates require different parts

Solution

1. Step 1: Check mate requirements

   Mates in SolidWorks connect different parts; applying mates between faces of the same part is invalid.

2. Step 2: Evaluate other options

   Angle mates can be applied to parallel faces; coincident faces do not cause errors; reference axis is not always required.

3. Final Answer:

   The faces belong to the same part and mates require different parts -> Option D

4. Quick Check:

   Mates connect parts, not faces on same part [OK]

Hint: Mates only work between different parts [OK]

Common Mistakes:

• Trying to mate faces on the same part
• Assuming parallel faces block angle mates
• Thinking reference axis is always needed

5.

You need to assemble a robotic arm where the forearm must rotate exactly 45 degrees relative to the upper arm and slide along a curved track. Which combination of advanced mates should you use?

hard

A. Angle mate for rotation and path mate for sliding along the track

B. Width mate for rotation and angle mate for sliding

C. Path mate for rotation and width mate for sliding

D. Distance mate for rotation and path mate for sliding

Solution

1. Step 1: Identify mate for rotation control

   Angle mates precisely control rotation between parts, perfect for setting 45 degrees between forearm and upper arm.

2. Step 2: Identify mate for sliding along curved track

   Path mates constrain movement along a curve, ideal for sliding motion along the track.

3. Step 3: Eliminate incorrect options

   Width mates control width, not rotation or sliding; distance mates control linear spacing, not rotation.

4. Final Answer:

   Angle mate for rotation and path mate for sliding along the track -> Option A

5. Quick Check:

   Rotation = angle mate, sliding = path mate [OK]

Hint: Use angle for rotation, path for curved sliding [OK]

Common Mistakes:

• Using width mate for rotation
• Confusing distance mate with angle mate
• Applying path mate for rotation
