Create Line Endpoint Tangent

[TFCO]

Hello

I am very new to Mastercam X3 I'm following the milllevel 1 courseware book. And for some reason can not get the tangent fuction in create line endpoint to work. It's not blending the line to any arc's. Any help would be great!!!

Thanks

make sure you hit the tangent button and then just get close enough to highlight the arc.the tangent line moves around the circle depending on where you get close to it at.then enter disired angle

Also make sure it does not snap to the midpoint, endpoint, quadrant, or center of the arc when you pick it.

review this on how to use the option.

Thanks for the replys! But I tryed follwing the steps as requested in the video and when I apply the cursor near the arc at any point it does not highlight the arc. If I try to select any point all it does is creates a line.

Thanks

In the line creation toolbar there is a tangent button that looks like a diagonal line and an arc. It needs to be toggled 'on'. It will allow selection of arcs and spline to create geometry tangent to. It will stay on once it is selected so may need to be turned back off occasionaly, I leave mine on nearly all the time. Also look for this button in other geometry creation toolbars, it can make all kinds of things possible or be frustrating if it is turned on and you don't remember.

Thanks! But this icon is on and we can not get this function to work at all. Plus we tryed the new update and still no good.

Do you have autohighlight turned on or off?

 

~settings ~configuration -screen

Autohighlight is turned on. Also my line will pick up in 1/4" increments anywhere on the screen in stead of allowing me to place anywhere I want. It does this with any feature ex: create a rectangle.

Thanks

In version 9 (I believe) you could create a line tangent to an end point by selection the arc and then the end point of the arc. A line would be created tangent to the arc from the end point.

 

In version X (2, 3) you get a warning-zero length line error.

do you have grid turned on??

 

see System Config/Screen/Grid Settings..

I think you have "Snap always" enabled.

 

If so ,turn it off.

 

right click in the graphics area

select Autocursor cursor and turn everything off but endpoints and arcs C/L

 

draw 2 circles

select line endpoints

make sure the horizontal and vetical buttons are

off and the tangent button is on.

 

If you hover over the first circle it should highlight.. then click to set the first endpoint

do the same with the seconf circle

Smit,

You can do what you want with "create line tangent through point". It is not a default in the sketcher/line toolbar menu.

THANK YOU!!!!! That was the problem.
