Drawing Vectors for Slots

Post by Robert Nichols »

I'm trying to design a baseplate for an assembly fixture and utilize slots instead of mounting holes.
Everytime I use the Draw Rectangle tool to design a slot 5/16" x approx. 6" long, and specify Radiused External Corners, I end up with square corners! Yet when I design slots which are 1/8", 1/4", 3/8", 1/2" wide, I get the rounded ends I am looking for. And just as I end up with square corners on the 5/16" slots, so too do I end up with square corners when I draw 3/16" and 7/16" slots. Hopefully, the attached screen capture will better describe the situation.
I'm only about 4 to 5 months into my journey with VCarve Desktop, but so far I have been able to get the results I'm looking for, but this has me stumped!!! Just wondering if anyone can tell me what may be going on or where I'm going wrong.

I'm not sure what you're trying to show me. I have been selecting the "Radiused External Corners" option each time I draw the vector.

Drop the Radius value down to .156

or...

Draw two 0.3125" diameter circles that are 6" apart (at the outer edges). Snap/Draw a rectangle that aligns within the center of both circles, then Weld the circles and rectangle into one closed vector...

or...

Draw a 0.3125" x 6" rectangle, then use the Fillet Tool with a 0.15625" radius setting and Normal Fillet selected, then click on all four corners

- three methods...and there is another (4th) method, too!

Or go into node edit, put the node arrow over the straight vector at each end and press "A".

That darn cat :lol: :lol: :lol:

Wow!!! Thanks everyone!!!

I hadn't considered the "rounding" issue when I entered 0.15625 as the radius value for 5/32"

As well, the alternative methods offered are filed away in the knowledge bank.

Ha! Was drinking my coffee, minding my own business, and a fifth method popped into my head! It’s kind of a “stupid method” that takes maybe two seconds longer to do, but thought it was funny that I thought of it without even trying.

Maybe someone else can guess the “fifth method” and post it to prove they figured it out (if you have nothing else better to do with your time). :D

Oh Oh!!! We're getting in "Stupid Methods".

OK, here's one:

Create a circle .3125"
Node edit the circle to create two half circles using Node Cut on top and bottom nodes
Move the right half circle Relative X 6"
Select both half circles
Click Join / Close - Vectors with a straight line (twice).

How did I do? :lol: :lol: :lol:

You’re too good, John! That’s exactly right!

I think the cat is now a skeleton.
