Drawing dimensioning questions from Newbie

GabiWearing — Tue, 25 May 2021 07:41:33 GMT

Hi everyone,

I am new to Inventor but have worked with Solidworks before.

There are some things in dimensioning drawings that I just can't find with searching and/or trying.

I appreciate some help if anyone knows how to do this here.

Thank you all for any tips!

Not sure how to do 3 other than double clicking and adding the text

For better or worth - the dimension 20, or the one you have sketched in red is totally wrong from the manufacturing point of view. You should have indicated the depth of the keyway instead. Should you cut a keyway once yourself on a milling machine - you would never made an attempt to put dimension for a keyway the way you show.

Cheers,

Igor.

What IgorMir says is completely correct from the point of view of the machinist but, if the cylindrical surface is removed along the length of the part, the way the OP dimensioned it will be the only way to inspect it.

In my copy of Machinery's Handbook,

ANSI Metric Keyways are dimensioned and specified from the near cylindrical surface, like @IgorMir

ANSI US Customary Keyways are dimensioned and specified from the far cylindrical surface, like the OP.

swalton, I'm working in the UK, we make it up as we go along.😊

@NigelHay Don't tell my boss, but so do I 😉

Very true. But I was commenting on the picture offered by OP. 🙂

Thanks it worked when I took the centreline out 😉

Thank you! Works like a treat!

Thanks, I was hoping for a setting or so 😉

In Regards to 1. This is how I learnt it long time ago... and we still do this now.

But I can understand that from the point of the machinist it is not how they set it up.

Thanks for the solution though now I know how to do it!

Q 1 and 2 are solved thanks to your comments.

For 3. do I really have to type the x45 deg every time?

For 1
I don't think you will get much love from the machinists.
For 3.
No, you don't have to. Please see the attached.

Inventor has a Chamfer Note tool which will do what you want (see image below). It is not as capable as it should be, and there have been many requests for it to be improved, but for most purposes, it will do the job.

All it does is allow you to pick an edge representing the chamfer, and a reference edge for measuring the angle, and gives the info in a leader note. The contents of the note are configurable via Styles. What it doesn't do is actually reference the information used to create the chamfer in the first place, and has no options for displaying the chamfer note as anything other than a leader.

Thanks for your answer.
It works the same way on my PC but only as a leader...
I was hoping for a horizontal or vertical solution. Will have to stick with the leader.
Anyway Thank you all for sharing your knowledge.

Sorry, I should read instead of just looking at pictures...

It is possible to get the result you want, but it is not quick. You can insert the actual parameter as text in a normal dimension, so it will be fully associative if the chamfer changes. This will be pretty quick if you have thought ahead and named your chamfer angle parameters for easy access in the drawing. Otherwise, you have to go back to the model to find out which parameter is the right one.

But if it's just 45° and will remain so, it's much quicker to just type it in as you have done.

Thanks for your answer!
I will check this out. Need to learn how to enter the variables anyway at some stage. 😉
