AutoCAD - Problem with 2d exercise

adamnowaczkiewicz1234 — Tue, 11 Nov 2025 20:31:50 GMT

Hey, I have a problem with a certain exercise 1096 and I'm encountering it again. I don't know what to do about it. I'll try to do r33 as shown in the diagram.
First question: is it possible to connect the blocked circle to this line?
Second question: is there an easier way to do this?
I also have a problem with the previous exercise 1069. On one side of the head, I have the center point for R - 16.5, but I don't have it for R -6.5. How can I do r 6.5?

Hello @adamnowaczkiewicz1234

Could you please share the drawing showing how much you’ve completed and where you’re facing difficulty, so I can help you out?

Hi,

Would you please show us your attempts for both exercises?

In the first diagram, I know that the circles touch each other, but I don't know how to make the circle touch the line.
In the second diagram, my idea was to lock the circle on the horizontal axis and then apply a tangent constraint. I keep finding similar problems and can't finish many exercises.

Draw a circle with radius 16.5 - 6.5 = R10 in the center point of the R16.5 arc.
Draw a vertical line in a distance of 54/2 = 27 beside the vertical center line.
=> The intersection point between both is the center point for the R6.5 arc. (Suggestion: Draw a R6.5 circle and trim as needed)

For the other issue post your dwg please what you have untl now.

Even if you didn't yet post your attempt, here a suggestion.

A well-meant suggestion: Before you use constraints, I would recommend training your geometric visualization skills. Otherwise, applying constraints won't really help you in the future. With the current exercises you are on a good way.

If you try and use all information shown on the exercise sketch, there is a way to draw it.

With the R33 circle, you know where it hits the dia 27.8 circle. There the centre of the R33 circle is 33 from that point. Draw a circle R33 at the end of the line. You also know that the R33 circle is 33 from the R8.5 circle. So offset that circle 33. Where the two intersect is the centre of the R33 circle.

Usually the exercise diagram picture is nicely to scale, so one can insert it into the drawing to check any gross errors. Unfortunately the sketch of the exercise 1096 is not nicely drawn.
