Editing extrusion

[baliasM74U3]

Hi All

What is the rigt approach to reduce the leght of the attached model by 894 from front (as in pic) ?

I can simply extrude cut that portion, but its not the right approach it seems 

Thanks

Basil

Hello Basil,
Do you want to cut the model 894mm from front?
If so, please see the video here.
Thanks,

Sorry mate, this is what i Knew. But I was searching for an alternate method which could be done by editing the "extrude feature". If some experts can help

I do not quite understand the task from the attached picture.

But ff you want to adjust the length from the final model. I think the quickest way is direct edit.

Hi,
You can change a start plane of Extrusion in R2020. But you will need additional repair for features after extrusion in most of cases you use this option.
Thanks,

Ireckon solidworks has got this option.

Can you Attach your SolidWorks *.sldprt "solution"?

The techniques used to model this geometry in Inventor was very very poorly done.

I have been using both Inventor and SolidWorks for more than 15 years.
I would model the geometry with identical techniques in both softwares.

My techniques would certainly look different than this example.

Sorry, I don't have any Solidwork Model. What is the perfect approach to make this model? By the way, this model was done by the previous modeller in my office. I will go for Sheet Metal>Countour Flange>cut features to make this in Inventor.

Thanks

While I take a look at this file - I recommend that you install the latest updates for your version of 2018.

See Attached file for efficient modeling technique.

I could have simply edited the existing file - but it was rubbish.

Hi Friend

I reduced the "840" mm from side A (see image) by editing "base flange direction 1" from 1500 to 660 (1500-840). I meant some steps like this rather than extruding cutting the 840 mm-- Done in SOLIDWORKS

How can I do the same in Inventor? Please find both the parts

Thanks 

Basil

Nope, that is not what you did in SolidWorks.

You added 660 to 1500 = 2160

I think you are getting closer to true problem  description, but subtraction is not what you did in this example.

Now I can understand more of what you want to ask, it's about design method in Inventor for quick changing.

You can use Edit feature to change the length like the picture.

Or if you want to become a more advanced user. I would recommend you focus on parameter design. Go to Manage/Parameters and update dimension d10 from 1000 to any number you like. You should name this parameter when you input it in the distance box e.g length=1000. So you can find it easier in the Parameters table.

Parameter design means you can control the part that you have designed using a defined parameter table. So you can update the dimension quick and easy.

Hi! I think you are looking for "Asymmetric" Extrude. Edit the Extrusion and select "Asymmetric" option (a shorter arrow with an opposite longer arrow).

Many thanks!

[baliasM74U3]

Heaps of thanks for detailed explanation and suggestion about parameters. Will do that

Can i Do that assymetric extrusion in Sheet Metal module > countour flange ? I couldnt find one .Please help

[baliasM74U3]

Yes, now I want to remove "500"mm from the end as shown in the image. Shall i do it by extrude cutting the "sketch 3" in the attached model ? or is their any other way i can do this in "edit features" of "Contour flange 1" ? 

Thanks

Basil

You've set up all the applicable parameters as, for example, "d17 - Change_Request".  To make the part 500 mm shorter from the front end, simply open your parameter table and change the User Parameter Change_Request from 894 mm to 1394 mm.

Finally, this is what I was looking for. Thanks everyone.

Thanks all who were patiently teaching me and introduced me to parameters. @SBix26 @johnsonshiue @marshall @JDMather @TheCADWhisperer 

I will make sure now onwards the sketches I make will be done using parameters.

Heaps of thanks....

Would like to start learning an FEA software as well. Please suggest which I can learn like this.

Thanks

Basil
