Cutout areas on built sub-assemblies
Some models have areas, sometimes spanning numerous parts, that need to be cut out after the parts are combined to form one sub-assembly.
What I do is to cut small slits in strategic areas of the cutout with the part(s) still on the page. The various parts are then attached to each other to form the sub-assembly. This allows the tip of the hobby knife to be inserted in the pre-cut slits and the blade is then carefully moved along the cutout boundary to remove the area that needs to be cut out. In the past I have assembled the parts without pre-cutting the slits. It was a struggle to insert the blade into the area to be cut out without mangling the piece. Anywho, that is how I do it. Does anyone else have a tip on making those cutouts?

From what I have encountered if the cutout area is removed prior to assembly the sub-assembly would not be able to be formed correctly. The cutout area provides support for the forming of the sub-assembly, then the cutout area is removed so the sub-assembly can be attached to another sub-assembly or the main body of the model.

I do something similar to your method, at least a small cut to then introduce the blade. Another solution for certain parts is to cut the area, then on the inside return the area to be discarded after assembling fastened with low paper tape adherence, which is used by painters, this prevents the piece from deforming and then easily removes the area to be discarded. For certain parts it works, the tape does not have to cover much more than the area to be discarded, a slight pressure takes it off and If not, a sharp knife cuts it easily and the piece is not damaged.

There are many models where cutting something out after assembly
helps with the initial assembly by leaving strengthening material in place. (as stated) Or...you just forgot to cut something out and have to do it afterwards. I have cut openings in unsupported sections of fuselages and wings with no problem. I just sharpen a Hobby Knife blade tip to supersharp. I keep a block covered with 2000 Emery handy on my workbench. And I dip the knifeblade into water every time I sharpen. Then lightly draw the knife tip over the area to be cutout. Multiple passes...keep sharpening the blade...don't apply any extra pressure. Don't push on the structure at all. Within a few passes, it easily slices through the card. I will leave corners or a few strategic spots until the very end, then slide the knife in and slice those spots to free the part. Sometimes you only need to make one or two slices in the surface. Enough to get fine pointed scissors in.

Great idea Doug.
I never thought of doing that. Thanks for passing it on. Paul

I used to use a new scalpel blade - nowadays I just resharpen a blade, taking extra care when I resharpen.
A few light stokes then to open a starting slit in the card....
