This is an enhancement request regarding dimensioning isometric views in Creo elements direct modelling.
The problem is that you are not able to smart draw dimensions that relate to the drawing on an Isometric view. When you dimension an edge on the isometric view it shows the actual length of the line on the view and not the dimension relative to the part. Below is a screen shot example:
When creating drawings it would be more flexible to have the option of showing a dimension in the isometric view. It can help isolate an idea or put a new perspective into the drawing.
Currently because there is no option to have the true length of the part displayed. The dimension has to be manually inserted which does take longer.
Creo Parametric does not also include this feature. I can understand because traditionally engineering drawings are best presented in a 2D format where dimensions are easier to read. The idea of having this feature enhancement has arisen from a number of our clients asking why this is not possible. The point had been raised in 2010 as an SPR but recently it has been advised to log as an enhancement request.
This feature could introduce a new level of engineering drawings where you can freely express dimensions on any orientation.
