I need help with multi-curved obtjects, such as a bonnet/ tailgate

[Anonymous]

I've been using Inventor now for a while and I get my way around in it. For my hobby and work, I don't have very complex shapes and basically everything can be done using the normal sketch and extrude methods.

However, for my hobby, I want to design a new tailgate for my 1:8 Porsche 911. And there I run struck, I do not posses the capability to get it. I tried loft, I tried using freeforms, but I just don't seem to get there.

This is an example of what I am trying to do:

It is probably not even difficult, but I am clueless in what to do and how to get there, I have been reading through internet, bought a expensive Inventor book and I spent now a full evening and day trying to get it to work in Inventor, I am at the point of throwing the PC out of the window :-).

But before I do so, is there someone who can point me in the right direction? Preferably a somewhat step by step?

Hi! Actually, I would not use Freeform or Loft in this case. If you remove the rounds, the spoiler has well-defined geometry like plane and cylinder. Please attach the file what you have here so forum experts can comment further.

Many thanks!

sorry but if you have no experience with such a thing, it will not be possible to use words to describe the solution
or a post with 100 .... posts

Also this - which is more up to date - but based on Fusion

@PaulMunford and other members her:

Can the Zip with F360 files be downloaded by anyone? I'm only seeing an XML entry.

Thanks @WHolzwarth, I'll report it to AU Support.

I've attached a copy of the Data set for your reference.

Many thanks, Paul.

I'll take a look now.

Here's a possible way of starting.

Hi @Anonymous,

For this part I would need 30 hours with sketches and freeform surfaces (here the result of 1 hour) 😞

Hello Everybody,

I am sorry that I am responding late, but I have been struck with the flu and had no interest of getting out of bed, there was no energy left.  Tonight is the first time I get back on the computer and start trying to draw this soon again.

I see some great ideas and will look at them closer somewhere this week, I mean; It can't be impossible right?  I will also keep this thread updated with my progress for future use!

For the record; I am not a noob with Inventor. I use it daily at work, but since the company I work for only uses machinable parts, there is no practice for me in it with fluent forms, it is an area I am just not familiar with (yet).

Thanks again and I will be back shortly!

That is serious skilled, very nice!

I worked a bit on the front bumper, basically to regain confidence again and that is succesful, soon I'll pick up the engine cover again, probably this weekend.
