Constrain angle of one sketch line to another

[nkloski]

Hopefully an easily solved problem...I am modeling something with a defined shape....I draw a line across the X axis in Sketch mode....great, it worked.  I draw another line of specific length, and then set the angle to 30 degrees...great worked.  Now I draw a third line from that second line, and want that new line to be at 35 degrees from that second line.

Problem!

The third line's angle is set to that of the global coordinate system, and I want that angle to be 37 degrees off of the second angled line.  Is there a way to tell that third line to base its angle off of the second line's angle, and NOT off of the global X-axis?

Thanks!

If you place the sketch line without specify (typing in) the angle of the line. You may go back after the line has been created and add an angular sketch dimension between the two lines. The sketch dimension too will allow you to specify the angle after select both of the lines.

See that attached image  below for reference, and let me know if you have any questions.

Awesome, thanks!

If I could ask one followon question.....In the attached screenshot, I was able to put in the angle, but I had to subtract it from 180....in fact I had to do that for all of the angles...how do I get the angle I desire without having to do the math every time?

FIX:  i answered my own question!  That angle is correctly described as 150 degrees, I am just asking for referencial angles, which would make a mess of things (blah blah line deviates from the previous line by 30 degrees would get hard to track very quickly).  So, I see that in that angle field you can put in mathematical equations!  So I just put in (every time)  180-whatever my angle is, and I get what I am looking for...thanks!

Hi there, 

Happy that's it could be done, but :

"You may go back after the line has been created and add an angular sketch dimension between the two lines. "

?.... How? What's the manipulation?

thanks

Have you watched any of the introductory tutorials in the Support and Learning section of this forum ?

The sketch menu has a dimensioning tool in it. You mich the two lines you want the define the angle between, enter the value for degrees into the UI filed and accept with OK. Done.

Hi Peter,

Thanks for the info. I haven't seek in the sketch menu, I focused my search througout the constrain tools.

And no, I don't have any sound device on my computer so I don't watch videos... but I can read btw!
