Hi,

I have done a 2D drawing to use as a template for an instrument panel, I have a number of "holes" that I would drill out on the actual job, how do I mark the centre of a circle so I know where to punch for drilling

Many thanks for your assistance

You can offset the circle , use a offsetdistance = R+1-R and you will have a small mark there, or Select line tool and move the cursor over the edge of a circle, press C on you keybord and you start to Draw a line from center of the circle

For marking centre of circles.  I use a Cross (from the 'points' tools),  and either, As Torfinn says use the Seke keyboard C,  or using centre snap.  After selecting the cross but before placing it, I go into its properties and change the size to what I need for the drawing.

There is also spot to select weather you want the center marks to show up when you dimension it, under Dimensions, Diameter, Advance format, Center marks, when I do a drawing for layout work I find it helpful to have some dimensions on the stencil just to verifie every thing is the right size.

Always leave the back door open, you never know when you might need to run out it.

Use SNAPS >> Quadrant Point >> Looks like a Circle with cross lines in it.

Select "Quadrant Point" >> Then draw the 2 cross lines in the circle >> Presto, Center marked.

TurboCAD 2017 introduced a "Center Mark" tool and a "Center Line" tool. They were available in all editions.

In TurboCAD 2018, they removed these tools from Expert, Deluxe and Designer; is now Platinum only.

What clever people we have preparing the User Guides.!!????
I attach the screen dump that appears when I ask the on-line "oracle" for help.   Please note that it says that it is available in ALL VARIANTS.
If I sound peeved then I have successfully communicated my feelings of frustration.   I hope someone in IMSI can fix it.
I have used the "C" system successfully even though an error message came up and said that I was able to do it because I had SNAPS on.

As an aside, my infrequent use of the Forum has been absolutely marvellous and helpful.  Thank you all!!

I have my AutoCAD Point tool set to "35" (in TurboCAD Explorer, "Drawing_Defaults) and use that when I want a center point object. I have to pick a regular Point first, then switch to AutoCAD in the Selection  Info palette or Properties. Once the change is made in TCExplorer, it will show up in "New from Scratch" drawings and can't be changed in those drawings. You can switch it to one of the TurboCAD points. There's a choice of 20 different points.
