Frame / Assembly help

Anonymous — Thu, 07 Oct 2021 09:08:17 GMT

Hi All,

New to the forums so apologies if anything is incorrect.

Started working for a new company 9 months ago, who predominantly used only 2D drawings (AutoCAD). My previous experience was CREO and we used the 3D models to produce the 2D drawings and analysis etc.

I've done some tutorials around assembly + the frame toolbox, and I'm wanting to know if I can create a "door" with a box section, that if I changed the height / width of the door that the box section would still have the "standardised gap" of lets say 5mm?

Above is the frame I've produced from the skeletal frame tool box. I've used the parameter tool so that I can increase/decrease lengths and it would change other lengths etc.

So I wanted to have a box section above this door, and be able to increase the height of the door whilst still having the box section above.

Thanks in advance!

Perry

Hi Perry,

I don't know if I follow you correctly but you can try to link the door to your parameters in your assembly:

This way you can you use the parameters of the door in the frame assembly.

Tobias

I'll take a look and see if I can figure out what you're suggesting. But I'd basically created a 3D sketch of the dimensions that we needed. I then created sub assemblies of the doors. However we often adjust the size of these doors, and it would obviously be much quicker if the box sections positioning was linked to the size of the door.

Can you Attach your Skeleton file here.

Derive Component will probably be your best friend.

(This process will be easy to do and is really what parametric modeling is all about.)

So I've attached the skeleton file. This is basically just the 3D sketch with the dims of the overall job. Please don't judge me too much as I've never really used alot of these functions prior to this job. And even then it's going off what I've managed to teach myself through youtube etc.

That's why I thought to link the parameters of the doors to the frame.

The dimensions in the frame need to be linked to the door dimensions:

So in your skeleton sketch you link the door parameters.

Then in your frame parameters you say height d1 (for example) = door_height

Now when you modify the height of the door, the parameter in the 3D sketch should change to this new height after update.

And yeh, I'm sure it's super easy! It's just because I haven't really done much Inventor and haven't really produced a component like this - my past experience is CREO with alternators.

I'll attach a door as well - it might help perhaps

Hi Perry,

You did not do anything wrong. Please refrain from apologizing. We are here to learn and help. There are a few ways to link parameters. Derive to the component or link to an Excel spreadsheet. Also, you can use iLogic rule to access the parameters in the members. In the top-level assembly, create a simple rule and then you get access to all parameters in the components at lower levels.

Many thanks!

I was working up an example, but it would help to have the door.

You Attached a *.iam file.

You must also attach the part files (*.ipt) as the *.iam is just a set of instructions on how to put the parts together.

You can create 3D sketch if you like - but I find it much easier to create 2D sketches as shown.

See Attached file below.

Note that there are far fewer dimensions for the same geometry.

Yeh, I did feel the 3D sketch wasn't the greatest.

Hi Perry,

Here is a screencast with parameter links. Before the screencast I first renamed the parameters.

You should definitly follow JDMather's advice on the sketch.

This should be enough info to look at for now. Thanks everyone for your help!
