Beam is becoming skewed/distorted in assembly

Hi I'm Alex and I am new to Inventor. We just switched to Invetor From CAD and have been learning as i go mostly. I have been experiencing problems that are leading to major setbacks due to requireing me to redraw multiple items.  With my job we have to use wide flange beams and square columns etc... I'm able to draw the indidviual parts and at times have no problem with anything being offset, crooked, skewed or anything. But I find that I'm duing something in the assembly process that is causiing my parts to become skewed/distorted in the assembly and thus also on my view layouts for prints. 

 

If anybody can help me with this problem i would greatly appreciate it!!!

 

Thanks again guys.

 

 

Alex

Your first part in an assembly should be grounded.

If you unground it and move it around your views will become skewed.

This can be fixed, but let's see what you really have.

Thanks for the response. I would love to attatch a file but we have an elevated confidentiallity contract and i cannot post any business work on here. Believe me i wanted to be able to show exactly what is happening but instead have to talk my way through it.  When you say ground it what do you mean and how do you do that?

Constrain the part to the pricipal work planes, axes, and origin point in the assembly file until it has zero degrees of freedom (can't move it by dragging).  When you start with a blank iam file and insert a part, the first part is (always?) automatically constrained.  You then constrain the subsequently inserted parts to the first part (or the assembly origins if you wish).

always automatically grounded.. (not constrained)

Do you have a home computer?

Can you download a 30-day trial and make something up that exhibits the same behavior that you are seeing in your proprietary work.  It is much easier to communicate with actual geometry files.
