TechDraw and Drawing Dimensioning construction angles

Postby steveKimpton » Thu Jan 24, 2019 4:45 pm

If I create an object where the holes line up along a construction line set at a particular angle, I can't see a way to convey this information in the tech draw or drawing dimensioning workbenches - see attached test object.

Of course I could use the x and y dimensions but the purpose of the tech draw workbench is to give helpful information to the person who has to make the object.

Any ideas?

Hi,

I'm sorry I'm not gonna give you a solution. But tell this way of locating seems dangerous to me.
First X/Y dimensioning is simpler (better ?) both for making the part and for controling it.
But also defining angle between hole center line and edge line is not enough : it doesn't correctly locate the holes. ;)
All in all, IMHO you should use a standard X/Y dimensioning reatively to reference faces. :)

You can create another sketch which gets the angle via external geometry. You can add this sketch to your TechDraw document.

Hi
My solution (home made)
Do a new sketch containing the 2 sides of the angle,
place it on the page
mark this angle in his page

Edit
My mouse has been faster than my shadow, there is indeed a tool "angle by 3 points
Sorry :oops:

Thanks meme2704. Sorry for the delay in getting back to this. Where is the angle by 3 points tool? I've failed to find it in either Tech Draw or Drawing Dimensioning.

It is available in 0.18 only.
