How to "exactly" place a point

Hi all, I have a question on how to place a point eaxatly on a corner or edge so that when I extrude cut it, it will no leave "left over" material.

The first pic is what my screen looks like when I am making a sketch on the face of this piece.

However, when I "extrude cut" it, this happens.

Now clearly I know that I "missed the mark" on that, and when I zoom in, here is the problem.

This happens often enough and has become "annoying" to say the least.

Is there a technique to avoid this?

Or possibly some setting that I have missed?
 
Make sure you have projected geometry and selected " Create reference figure" And "Maintain association"
 
Thanks guys, that did the trick.

Now is there a way that I can see the lines between them? like some sort of setting that will show the lines? I have looked trough the properties section but didn't see anything.

Here it is after I constrained them, and then extruded them.

but as you can see here @HaroldL made it so that it looks more like a board.

Harold's image is of an ASSEMBLY of parts, so far you've just got a single part - nothing for there to be lines between. Only Edges of the part will show up.
 
As you were gentlemen.

Filleting them works

Edit: @DavidJ we were typing and posting at the same time. But I do see what your saying.

If someone knows a faster/better solution than "filleting", I am all ears;)

If you want to have the edges visible, then don't make the sketch edges co-linear, keep them slightly apart from each other, so that they are in effect separate entities, 0.0005" will be ample. (this also applies to the board end edges, in the upright rebate edges, if you also want the board to show in it's entirety).
In the attached file, I patterned the "board" distance, by an extra 0.0005" to show this (if you try editing the pattern and make the distance 1.000" the two will merge and the line disappears).
Really though, you should be making this as an assembly, rather than trying to do it all in sketch mode.
Hope this makes sense.

Thanks for that.

The part in red is something I am trying to understand.

My current plan is to make "one big sketch", then label each of the individual sketch's with their corresponding dimensions.

Like below.

Once I have the sketch done, I will then go back and make a file for each board.

From those files, I will try to make my assembly and be able to generate a BoM.

At this point, it has more or less, become an exercise in working with Alibre,
 
I now understand your intentions, however this is about Design Methodologies and what you are doing would be a Top Down design, as explained in the attached old video.
Although you think this may be beyond you at this time, it would be worthwhile having a play with Top Down design in the assembly workspace and see how you get on.

It's funny you found that video, cause I just found it too, and came here to post questions.

Yes, that is exactly what I want to do, a "Top-Down" design.

I have been trying to do one, but I am getting stuck.

In that video at about 1:24'ish he clicks on a "new part" tab, and for the life of me, I can't find anything like that.

Also my top ribbon does not look like that either.

Any ideas?


Edit: BTW, What I think is beyond me is the "Bottom-Up" methodology. I still have no idea of how you make a part for an assembly that has never existed before?

However I fully understand the concept of the "Top-Down" method, and that is exactly how I would like to build my deck, and how I visualize how to build something.

@Runs With Scissors, I was going to record a video of how I modeled my table saw stand, but now that you've posted a screen shot of the "layout sketch" of your deck I thought I'd use that to create the video. This will be specific to your deck using a Bottom Up method, Top Down will not work since it uses the default part templates.
So, I hope you find this helpful; post any questions that may come up in using the template and the workflow that I illustrate using.
The uploaded template should work for you at your current version of Alibre.

I'll post another video to show how to create a drawing and BoM with the deck showing the BF in the BoM table.
Note that I will not be posting these videos on my YT channel.

@Runs With Scissors, And here is the second video showing adding the deck to a custom drawing format and a BoM set up to add custom columns by editing the BoM Table.

The process that I've shown in the videos has worked for me without too much hassle. I did update the drawing template lately to include the Mass for Drawing parameter based on a video by @Joseph_L and the video he has on the Alibre YT channel.

Here is my drawing template, put this into your custom folder location so it doesn't get lost or over written. I am also adding the script that was used to calc the Mass for Drawing that I got from Joseph's video, put that in your Scripts folder.

That video is quite dated now and is from an earlier version, hence the Legacy Interface, in the title.

Just be sure that you are in ASSEMBLY mode/workspace and you should see the Icons below (The New Part tab has the same Icon, but is now simply named Part):-

Wow sir, that was "above and beyond"!!!!

I really do appreciate it. I especially like when you tell me "how" to do things (for instance when you say "control, right click". For a noob such as myself, that helps immensely.)

It will take me a few days to go back through and digest all the new information, but I will post my results.

Thank you again.

I will look for it today, thanks.
