I owe you a bugreport but at the moment i have no time ..... sorry.

I look forward to it. I've just about worn out the last test file you gave me.

Hi,
First of all I'd like to thank you all for a great work! It looks really good.

I don't know if it has been reported before but I think I've found a bug. Dimensions of an isometric view are not correct. Screenshot attached.

Dimensioning isometric views is a whole different ball game. I don't think wandererfan has implemented this yet.

It sure can be handy though. Back in 2007 I evaluated three mid-range parametric CAD modelers for the company I worked with. Dimensioning iso views was a feature we needed. Out of the three programs, only one had this feature IIRC. Things may have changed since though.

Until/if it is supported by TechDraw, maybe it would be best to disable dimensioning iso views? If that is possible.

We tried to do this automatically, and it was a shambles. But you can certainly do it manually.

The link dimension tool allows you to assign an edge from the 3D view to a Dimension in the 2D view. Once linked, the actual (True) value will be used instead of the 2D (Projected) value.

Thanks @wanderfan. It looks like a workaround.

One has to be careful since the lack of topological naming is showing its face again. After adding a fillet.

What is strange is that the dimension value has not been updated.

Thanks, but how do I use it?

After selecting an edge then creating a dimension on an ortho view, I tried to

• Select the dimension then the corresponding edge on the iso view
• Select the corresponding edge on the iso view, then the dimension
• Select the dimension then the corresponding edge's vertices on the iso view
• Select the corresponding edge's vertices on the iso view, then the dimension

Everything I do results in this error message

Can't link a dimension to this selection

A couple of bugs which appeared lately (not sure which commit):

• In the Insert Projection Group utility, Automatic scaling doen't work anymore
• Neither does Custom scale, at least there is no more live preview. Scale is only applied once OK is clicked
• After ticking the secondary projection checkboxes in that order: top, right, front top right, the secondary projections are all displayed like the first selection:

  It is only once OK is clicked that the views are properly displayed.
• What exactly is "Document" scale? When selecting it, the projection group is scaled very small on the default A4 page.

  (I just now noticed that the dimension on the right view somehow got switched, it was linked to the bottom edge.)

Would you prefer I make proper bug reports on Mantis?

[f3nix]

Thanks, but how do I use it?

Hi @NormandC.

You have to select an edge in 3D view then switch to drawing and use the link function.

HTH.

Oh! Thanks! I thought that by "3D view", wandererfan meant the iso view in the page.

EDIT: well it doesn't work for me. The linked dimension sees its value changed to 0.00mm.

I'm starting to wonder if there's something wrong with the Ubuntu Daily Builds package!

There is a small bug in the creation of a projection group. The rear view is wrong at setting of the checkmark as can be seen in the projection of a Part wegde. The view gets right after changing force and back of the view direction.

Edit: I see Normand was faster than me!
