Join a circle to two lines
Join a circle to two lines
All,
New to VCarve Pro and I'm not quite sure what I'm messing up in the simple file attached. I've drawn a circle tangent to two parallel lines but I can't get the vectors to join. I've double checked my dimension and it looks okay to me. Any tips as to why I can't join the vectors and then trim away to lower part of the circle to leave a radius at the top?

You can't join a closed vector, the circle, to another vector.
What should the end vector look like?

Re: Join a circle to two lines
Not sure exactly what you want to join, but if it is to create a rectangle with a round end then the scissor tool to snip off the bottom of the circle and the overhanging line ends.

That's exactly what I'm trying to do but the trim tool does nothing for me. You created that from the file I attached?4DThinker wrote:Not sure exactly what you want to join, but if it is to create a rectangle with a round end then the scissor tool to snip off the bottom of the circle and the overhanging line ends.

Yes. The scissor tool is all I used.acs_user wrote:That's exactly what I'm trying to do but the trim tool does nothing for me.

Re: Join a circle to two lines
I was having issues with a similar shape but with lines angled @ 30 degrees. I could draw the shapes but couldn't join the vectors. I ended up using the join / close vectors by moving end points tool. I'm still not sure why I needed to do that. Thanks for the responses4DThinker wrote:Yes.

Re: Join a circle to two lines
Darn, I can't remember it, but maybe this will trigger someone else's memory. At the last user conf in Vegas, they presented a way to ensure you had perfect tangent lines to a circle. A nice shortcut. Its likely in the presentations some where. Once there then using the scissors to cut should work fine. But I remember trying to make the lines manually then using the shortcut taught, and was amazed that it was a) easy b) much better than I could do manually.
Anyone have those presentations and want to post the basic steps to do that?

Re: Join a circle to two lines
Thanks for posting this. Any idea why the arcs and lines aren't tangent when drawn with proper technique? I don't have this issue in other CAD programs.highpockets wrote:

Thank you John,
Figures it would be something as simple as press "T".....

Re: Join a circle to two lines
For what it is worth, the scissor tool won't work if the vectors are (G)rouped.

Re: Join a circle to two lines
Here's an example where I'm trying to draw an arc tangent to a circle and another arc. I tried the "T" shortcut but I can't get it to work for me here. When I use the clipping tool, it clips back to my construction line indicating the 10mm circle isn't tangent to the 45mm or 390mm circles. Also, I tried to use the fillet tool to add a 5mm radius between the two but it's squaring off the arcs. I'm obviously missing something.highpockets wrote:What are you calling "proper technique"?

Thanks John,highpockets wrote:See if this helps.

adding the trimming lines (in red on the attached drawing) was what I was missing. Once I added those, I was able to trim the fillet. I mistakenly thought they were already touching at those points and I should be able to trim them. You saved me some hair on my head.
