Constraint endpoint of one line to some point of other line

[Anonymous]

To start with I use Autocad 2016

I also use Inventor 2016.

In inventor working with constraints is pretty straight forward.

In Autocad I encounter an issue.

I simply want to constraint the endpoint of one line to a different line.

Not to the end- or midpoint of that line, but just on that line!!!

And that is the problem, Autocad wants to snap to the end or midpoint when using Coincindent Constraint, and I don't want that.

Using Dimconstraint and put the vallue to zero seems not the right way.

Please tell me the simple solution

Try This :

1. COINCIDENT
2. Select AUTO CONSTRAIN from Commandline
3. Select the Rectangle and Line (The Rectangle and endpoint of Line should be intersecting)

Did it work?

Hi,

after the first line was created I would:

• activate CONSTRAINTINFER
• start command _LINE
• using <SHIFT><mouse-right-click> to get the object snap menu ==> select "Nearest"
• pick the start point of the line on your first line
• pick the end-point of the line

Now you have a second line which has a start point on the first line, but not fixed to the endpoint or midpoint.

@S.Faris: Nope, doesn't work, 0 coincident constraint(s) applied it mentiones

[S.Faris]

Did you move your line and coincide it with Rectangle before doing the COINCIDE Command? Because it works for me.

@Alfred.NESWADBA : This works but seems much work to achieve this, is the no easier way?

Maybe I got used to Inventor too much....

In inventor you use coincident constraint, pick the endpoint of line 1, and some point on line 2, and ready.

But Inventor and Autocad are not exactly the same.....

Hi,

>> is the no easier way?

Not that I know of any to use the NEAREST point as constraint info.

>> But Inventor and Autocad are not exactly the same.....

They are completely different, and one of the differences is: constraints is one of the basics of Inventor, but for AutoCAD it was built in much later more like an add-on.

[S.Faris · Accepted solution]

if you can't get the first method try this:

1. Select COINCIDE
2. Pick the ENDPOINT of the line
3. Press Enter to choose Object
4. Select Rectangle

Hope this gets the job done

Hi,

@S.Faris 

That is the easier solution @Anonymous was asking me ... I did not know that ... thx!

     @S.Faris  : This works, I just don't understand why I have to enter in between ?

[S.Faris]

Command Sequence Below

Command: _GcCoincident
Select first point or [Object/Autoconstrain] <Object>: 
Select second point or [Object] <Object>:
Select object:

Reason

That is to change the command from Select second point to Select object

Thanks, now I understand, I also could have typed "O'' and than enter, for the same result (but 1 more strike on the keyboard)

[S.Faris]

Can you Accept that as the Solution Inorder for future user to  find it Easily

[Anonymous]

Yes I can and will

Thanks a lot guys!

You can also draw another line on the first line and set them to colinear, then contain the second line to whatever length you want and use coincident at the end of that line
