Drawing in BobCad

[Todd Price]

I have access to Sorin's site. So far from what I've looked at, there's nothing really there for us newbie's. It's pretty much advanced stuff. I'm sure I'll get the hang of it one day.

Hi Todd, try this, I think is the easiest way to do it.
First make coordinate center on x,y=o R1.25, click continue and then go x=2.5, x=5, x=7 with their radius. Then make a point coordinate on y=1.25 and y=1.75, join them, and the point at y=1.75 translated by increment x=0.5 on the change tab. then just make the arc the by snaping. make a line tangent on that arc of 1.00, make a point at the end of that line and translated by increment to x=1.00, snap the arc and the rest is triming and tangen. then just mirror the part on x in the change tab and good to go. this took me about 4 minutes or less

Regards, Andres.

Todd I started using the lone method. I sketched a line and set it to x o.oo then offset that line using line parallel by 2.5", repeated and then did the last one by 2". I then put a point in the middle of each of the two end lines and connected those with a line. All the intersections gave me the centers for all the radi that falls on the centerline. I then use arc point center to create circles of the given radius for each position. I could have selected the beginning and end degrees but I was in a hurry and used this method instead. I then trimmed the right side radius to the last right end line at 90 and 270 degrees. I copied the centerline to the 90 degree end of the radius and trimmed it to the second line from the left. This gave me the length for the upper part. I put the smaller radius at the left end of that line put the short section of line at the upped end of that radius then filleted that line with the far left end line with the .5" rad. I selected the upper half and mirrored using the centerline. Finally I trimmed the far left circle and end line to complete it.

You know it's funny. Typing all this takes me longer than to actually do the part.

I hope this helps.

The rectangle feature is the fastest but drawing a continuos line and coming back afterwards with fillets would be easy as well.

Sorin does have a video on how to make rectangle. (the one called Keyhole-part draw steps you through a drawing)

There are a few videos on Sorin's download page that are really basic beginner stuff while others do get more advanced.

If you need something specific just ask Sorin and he can help.

This is mostly the way I did it. I like to do 1/2 then mirror copy rotate.
