Datum levels missing in one view

Anonymous — Fri, 21 Apr 2017 16:33:53 GMT

I have three datum levels not showing in one view. The top of foundation, bottom of foundation, and basement levels do not show on the east elevation view. They do show on the three section views I have and on the other 3 elevations.

I checked VG, toggled levels on/off still did not display

Verified they are inside crop region in all other views, and all at set to 3D in all other views

Tried propagating from west elevation to east elevation, still did not display

out of ideas, I'm missing something obvious

Their 3d extent may not pass those views. Go to an overall plan view, turn off view crop region, draw a big Scope Box cover the entire the model, set its Height to be higher then the model. Go to a section or an elevation view where you see all Levels, select all of them and set them to be associated to the Scope Box above.

Hi @Anonymous

Congratulations on earning the rank of an Explorer in the Autodesk Community!

Levels/grids and sections are referred to as datums and have 2D as well as 3D extents.

If you right click on a datum in a view, select maximize 3D extents from the menu. This will expand the extents to the full boundaries of your model and should make your datum to appear in your appropriate views.
If the datum does not intersect a view’s plane (or does not intersect the plane in the correct way), then it will not be visible in that view.
If you have cropped an exterior elevation and the Level 3D extents do not cross the boundary of the elevation, you cannot see the level in that view.

If it is still not shown in any view, create a scope box for datums.

Scope boxes control the visibility of datum elements in views whose cutting plane intersects the scope box. Scope boxes are particularly useful to control the visibility of datums that are not parallel or orthogonal to a view.
Under your drafting tab, select scope box, use it to draw a 3D box completely around the extents of your model.
Now in elevation add another level (this will be temporary), right click and choose “select all instances” go to the properties and there is a category called extents.
Where it says none, click and choose your scope box for the drop down menu. Then click okay and your levels should now appear as there extents have been adjusted to that of the scope box.

Good morning Viveka,

Sorry for the delayed response, I decided not to slow my progress in the project and live with the missing Datum. Today I opened a new project Residential-Default Template and realized the missing datum are part of the template, rather than something I did in my previous project. I did follow your suggestions by drawing a dummy wall system, drawing a scope box around it in the first floor floor plan switching to the west elevation view , adding the datum (temp) and selecting all in view, and changing the extents to scope box 1. Oddly all the datum disappeared. Not sure what happened????

In the end I simply deleted the three datum that don't appear in the east elevation view, and then redrew them. This solved the problem, now all datum appear in all elevation views. The root problem seems to be in the Residential-Default Template (2017 Version), and the quickest solution seems to be delete/redraw.

Thanks for your help.

Regards,

Keith

Good morning ToanDN,

Sorry for not getting back to you sooner, I appreciate your assistance. I also had a suggestion from Viveka who suggested the same approach. I'm hoping you can see my response to her to avoid typing the same response twice. If you can't see my reply to her let me know and I will provide you more details.

Thanks for your help.

Regards,

Keith

Thanks for the update.

I will look at the Residential template when I have a chance, just for my own curiosity.
