Fit view issue

[CNSZU]

Hello,

It seems the command "Fit“ to fit the contents of a view to the screen works differently for different features. For example, if the part consists of an extrude feature, the Fit command works perfectly. However, if the part contains a Through Curves feature (with Preserve Shape unchecked), the Fit command will zoom out more (include more blank space in the view), even if the Through Curves and Extrude feature look EXACTLY the same. This is preventing me from creating a layout with several views and using the Fit All command to fit all the contents. The part in the views is too small with too much blank space.

The attached image shows what the test feature looks like. The top image shows the Extrude feature with the Fit command. The bottom image shows the Through Curves feature and the Fit command. Both top and bottom image has the fit percentage at 100%. As you can see, the model in the bottom view is much smaller (and clearly smaller than 100%). What should be done to rectify this?

I am pretty sure that the reason a through curves will be smaller when "Fit View" is used is due to the Pole Structure of the face. - Which the Extrude doesn't have. Try display the poles of that face and the poles will be on the screen.

What is it you try to accomplish with the layout ?
Can't you zoom in on the lower example ?

I'm not sure if the Fit view problem is due to the pole structure. Sure, the Through Curves feature has poles, whereas the Extrude doesn't. However, there are two settings for the Through Curves feature that affect the Fit view command: Preserve Shape and Body Type. The ONLY combination which causes a failed Fit view is with body type SOLID and Preserve Shape OFF. But if you create the Through Curves feature as a Sheet, then create Bounded Plane features and the Sew command to finally create a solid, the Fit view command again fails. So this is really puzzling.

The reason this is causing a headache is because I need to create a 9-view layout. With so many views on the screen it's vital that each view is zoomed in as much as possible. That's why I do a Fit All with the Fit Percentage set to 100%. But because the Fit view command fails if the model contains a Through Curves feature, the views of the model are zoomed too far out.

Just a guess, but have you toggled the Z Clipping Plane option in the same menu that the Fit Percentage is, to see if that helps your problem.

The Auto Z clipping plane options don't make any difference.

If you use the 'Preserve Shape' option, then topologically there is NO difference whatsoever between the 'Extruded' or the 'Thru Curves' models. That being said, why can't you simply use the 'Preserve Shape' option for your models?

John, the "test model" I posted an image of is a very simple example. For Through Curves features that use more complex curves as sections, the Fit view results are different. In these cases, even when checking on Preserve Shape the Fit view does not work properly. Also, in many cases I cannot use Preserve Shape because I need to set the Alignment to Spine Curve to create an optimal surface.

Then you're just going to have to live with manually edting the view scales of your layout, aren't you...

OK, no problem. Anyway, thank you for looking into the issue.

BTW, I've created some example files similar to the ones you created and show the images of, and I've gotten them to behave the same way that you've described and I'm going to take this up with our display people and if I learn anything I'll pass it along.

Excellent, thanks.

I'm still curious why you want a 9-view layout... ?
Do you run on a 70-Inch monitor ?

[CNSZU]

The reason is simple, after finishing a part I use a 9-view custom-made layout to quickly present 9 different custom-made views of the model with Advanced Studio Display on the screen. Then I take a screenshot and give it to a client for review. So, with so many views on a single page it's important that each view has as little "margin" as possible in order to clearly see the model.

I guess what you're creating what could be called, for us old film camera types (I used to do freelance photo work while in engineering school) a digital 'proof sheet'.

OK, I've found a workaround, but first a couple of questions: You say that you're creating a nine-view layout which means that the different parts must all be in the same file, correct? If so, how was that done, are they Components in an Assembly or different solid bodies in the same part file? If they are Components in an Assembly, simply make sure that they are all loaded as lightweight representations (NOT exact) and then the 'fit' should be more consistent irrespective of the fact that some of the models will have B-surfaces and some will not.

Yes, the part is an assembly with components. Opening the part as lightweight solves the Fit view problem IF the shading type is Shaded With Edges or Shaded (but the faceting quality is very low). Anyway, this is not the real issue, because I need to use the Studio Shaded View (Advanced Studio Display) for a realistic presentation of the model. In this shading type the facet quality is higher but the Fit view problem reoccurs (for more complex surfaces).
