I can't obtain tan/tan in two ends of a line. I want to tangent a line to 2 circles. I saw Michael demonstration but I obtain one tan/tan not 2. What to do? Excuse my english.

The way I do it is to drag out a construction line from the first circle to the second circle. If you try and do it by eye from the first circle when you drag over the second circle you should get a "tan/tan" point to snap the construction line to. Release the mouse then go back and draw the line using the construction line snapping points. I find sometimes after getting the "tan" snap on the second circle you sometimes have to drag the mouse ever so slightly to get the "tan/tan" snap.

Hope this helps.

Update: The way the other's describes works as well. There is no need to create a construction line. The trick is to roughly guess where the first tangent will be.

Hi Big Sister,

Place the cursor above the object/snap button and click on the white arrow button.
Check if all snapping options are activated.
If not then place the cursor on one of the options and rightclick,to activate them all.
At least the on-option and the tan/tan-option must be active.

Hi Big sister - could you possibly post a file that has the circles in it that you want to construct a tan/tan line between? Then I could show you exactly where to click to do it.

The main part that can be tricky is that the first point that you place on the first circle must be somewhere in the general area (like with 100 pixels or so) of where the final tan/tan line is going to be, if the first point is too far away the tan/tan snap will not engage. It does this because the tan/tan snap unlike other snaps modifies that previous picked point and if it moved it a really far distance that could be strange in some cases where you were not wanting to get that particular snap.

But if you can post your particular circles I can do a demo for your particular case to show you where to click.

- Michael
