# how to use mates in slope part solid work

Okay, let's go!
Maybe someone will find it useful, but it's a simple design.. ))

1. ### Step 1:

That what we need for modeling - 2 "i-beams" and "angle-beam"

2. ### Step 2:

Measure distance between planes of i-beams

3. ### Step 3:

and between holes of angle-beam

4. ### Step 4:

The distance of the hole welded lug you choose 75 mm, let's do so

5. ### Step 5:

Make 3D-sketch
Look at mates
The distances I made the way I liked, you can make like yours, because it not my project

2 lines 75 mm Along Z-axle

6. ### Step 6:

Point situated on plane surface of i-beam

7. ### Step 7:

2nd line point - on surface of i-beam #2
The distance of 150 mm got from my mind to the circle line =)

8. ### Step 8:

Now we must make PLANE for new sketch
Choose 75 mm lines for that

9. ### Step 9:

Make sketch on this PLANE
I made 2 lines of 200 mm

10. ### Step 10:

Mates look at screenshot

11. ### Step 11:

Now you must edit i-beam, and using Convert Entities - convert the 200 mm line to plane of i-beam

12. ### Step 12:

Extrude thin and make hole
Make the same with the 2nd 200 mm line

13. ### Step 13:

But by the reasons you make patterns wrong way and not made configurations, you'll have the lug at all beams
Not problem, but can be done more perfect...

14. ### Step 14:

And now we are ready to do the mates
1) Coincident

15. ### Step 15:

2) Concentric

16. ### Step 16:

And this is how it looks now

Enjoy!
